Hellwig's Pro-Touring rear sway bar P/n 55868 is now available for 68-72 GM A-body applications. This kit relocates the sway bar from the lower control arms to the rear axle, which improves handling by allowing the suspension to freely articulate. The sway bar is made from 1-1/8” diameter alloy tubing to reduce weight and incorporates 3 holes to adjust roll stiffness so that the suspension can be tuned to match your suspension upgrades and/or track conditions. The sway bar is connected to the frame with adjustable end links that accommodate stock or lowered ride heights and incorporate hourglass bushings to allow 5X more articulation than a straight cut bushing. The end links are connected to the frame with our integral clevis/tailpipe hanger (pat pending) that allows factory exhaust hangers to be used with the kit. The kit includes polyurethane bushings and all hardware required for installation.

p/n 55864 for 64-67 GM A-Body applications will be available later this month. This will mount the same, but incorporate a 1-1/8" diameter tubular sway bar engineered for the 64-67 A-body frame.

Got a price for the 64-67 bar?

Dave,

Do you have any other pics illustrating how far this bar will hang down below the differential cover?

THe sway bar should be even with the bottom of the cover. The end links are adjustable to allow the bar to be oriented correctly. http://pic40.picturetrail.com/VOL280/10740363/22704483/378846619.jpg

The 64-67 Bar will be the same price as the 68-72 bar. It will be available in 2 weeks. SC&C has promo pricing on the 68-72 bar p/n 55868 at $210 for the month of December.

More pictures of our integral clevis/exhaust hanger attachment that allows the OEM muffler hangers to be used.

I`m really excited about this bad boy! It basically yields the same performance as our Spohn ProTouring adj. bar but with a MUCH cleaner installation, lighter weight, less NVH and at much lower price point. You gotta love it. :D
Those who preordered these with us expect a call today. :yes: Those who didn`t...what`re you waiting for? :p The intro price only lasts for the month of December. Mark SC&C

Canīt wait :-) Merry Christmas to me hehe
Looks great !

Where are they made? I couldn't find anything on your website saying if they are made in USA, or elsewhere...

100% made in the USA in Visalia, CA.

Dave or Mark (Mark, waiting for PM reply)

Do you guys have the 64-67 units ready?

Im in, calling today Mark for my order and a short "brain pick"

100% made in the USA in Visalia, CA.
Awesome, I'll be ordering mine soon... you should really put that up on your website somewhere, that's a huge selling point for me. :)

x2

Everything on my car at this point is made in the US and verified as such. I am doing my damndest to keep it that way. VERY happy to continue the theme with these bars. Needs a tag somewhere on the hardware. I like showing that stuff off. Tempted to paint the "made in the USA" marks on my other suspension pieces with different color paint just so it stands out more....but im lazy so probably will just point to it instead. :D

Left a msg at SC&C just now. Quick Q's about my cobbled set up and soon as I get in touch will be buying front and rear. Cool stuff.

RYU- We are finishing up the 64-67 bars. Probably one more week and we'll be ready to go live.

Placed my order with Mark last night. front 1 1/4 hollow and the new rear adjustable.

I am anxious. Only thing that sucked was actually hearing in person, from a voice like Marks on the phone....the B Body (what did ya do that for?) spiel. Thats rougher to listen to than to read. lmao

Now I gots more saving and spending to do cause I cant listen to that spiel if I ever have to explain my suspension. Thanks Mark.....:D lol

Our tubular bars are CNC formed but you might also like to see our hot forming process. This is all done here in Visalia, CA

Hellwig Hot Formed Sway Bars

Thanks for the orders. We sold out our first batch but will have more done tomorrow afternoon. For those in CA - you should have them by the end of the week.

:hurray::thumbsup:

Are the 64 to67 bars out yet???

Ordered mine through SC&C yesterday :thumbsup:

Received mine about 5 days ago.

Very happy. Have to relocate / bend / move brake line on the rear crossmember for the mount but no biggy and is stated you mad need to do so.

Have to check fitment more, looks to be a bit close to the truck arms on my chassis and dont know how close it can be and not interfere (or if it will at all) with lower arm articulation.

D - do you know? I dont know if it matters with how the rear end moves, etc. how close it can be to the lower arms when mounted up. I dont know if there would be any movement there that might cause an issue if the sway is only an inch or two away from the lower arms or if the movement is the same and it doesnt matter. Appears when mounted it will be very close, dont know if it even plays a role in normal suspension articulation and this bar being mounted rear end / rear cross member.

kind of tight with the truckarm / panhard bar and since I cannot fully mount it until the body is back on the frame with weight on the wheels I can only do the brackets on the rear crossmember right now.

Sorry to put this here, just a shot in the dark.

Well, just thinking about the different arcs the arms and swaybar would swing in, they should be tightest at full droop. If you have clearance with the rear hanging, you should be fine. :)

Perfect. Thank you, as always, Obi-Wan Kenobi. :D

The 64-67 bars are out now. Part # for the 64-67 is 55864.

just got off work and tried to order with Mark @ SC&C but i'm sure he's closed early for NYE. hope he gets my vm!

I left a VM and also 2 emails a week or so ago and never heard back from him, guess I wont be getting the special deal before end of yr. :(

Bill

I also left 2 e mails this week,,,no response. Hope he is just closed down for the holiday and the special will be good for a while. After all the month went by and the 64 -67 bars just came out.

I left an email last night with the sales staff. Hope I get the deal, but that's what happens when you wait til the last minute! Duh!

My order just went in,,nice talking to Mark,seems to be real excited about these new bars.

well its been over 10 days and nothing yet ,,,left him an email thursday,no response.Mark,if you see this get back to me and let me know the statis,Thanks,Mark

Call him and if no answer leave a message.

Mark sent in a whole list of orders about a week ago. We sold out our first couple of runs and are waiting for more bushings to come in to ship out the next batch of orders. If you would like to check the status of your order you can call me at 559-734-7451 x36.

Talked to Mark today and he explained the statis the same as Dave posted above. Thanks !

well its been over 10 days and nothing yet ,,,left him an email thursday,no response.Mark,if you see this get back to me and let me know the statis,Thanks,Mark

you must have been one the buyers of those stainless door strikers sold here on team chevelle ;)

Which, BTW, can now be had for about 40 or so bucks from musclerodz. :D I just bought a set and I like them. Also a set of billet hood bumpers / stops from Fesler through them. Cool stuff.

That dude took people for 100+ on those things. He really deserves to have his face caved in with a monkey wrench.

still waiting on my bar for the 66 also but no big rush for me. last Mark said Hellwig was busy making parts for the army. take care of the men first!

I just talked to Hellwig, the parts are in and bars will ship on Monday. :) Thanks for being patient guys. We sold way more of these way faster than we though we would and just got a little behind! :o:yes: Mark SC&C

Sway bars will be shipping out by Monday for all SC&C orders.

Anyone get theirs yet?

mine came in

Mine came home yesterday.

still nothin today.....

I got mine a few days ago. :)

again nothin,,,,,

mino65 - send me a pm of your address and I'll see if we have a tracking # for you.

pm sent.

I'm just curious... what are you guys running as a front bar to pair with this rear bar unit?

I know spring rates and possibly shocks matter in such a setup so if you're so inclined to post those figures as well i'd appreciate it.

Mods: if this is OT please let me know and i'll delete.

If its stock suspension geometry, our 1-5/16" front bar works well. If you have a tall ball joint or tall spindle setup, we reccomend our 1-1/4" front bar. P/n and specs are as follows:

55703 1-5/16 x .25" wall FSB
55706 1-1/4 x .188" wall FSB

I'm going to try out the OEM 15/16th front bar for now...

750lb front, 175lb rear springs. adjustable shocks at all corners w/ the big body varishocks up front.

It's definetly not going to hurt, but I don't want to end up like some of our members with 6pair of springs and a dozen front and rear bars... :p I figure I'll get it good enough until I can get corner weights and do the math.

Hey Mark,

I guess I missed the boat on the intro price. What's the current market price for a '66?

Does anyone have a 64-67 instruction sheet they can email me so i can see how it gets installed?is drilling the frame required?

Thanks

You enlarge two existing holes in the frame and use the frame brackets as a template to drill two additional 13/32" (.406) holes in the frame. This can be done in your driveway with the vehicle on jackstands. I did a few myself in my driveway during development of the kit to make sure it could be done by the average DIY'er.

Does the sway bar get installed with the rear hump under the rear facing up or downwards?



Thanks

Rear hump faces down.

Rear hump faces down.

Cool thanks,should i use the middle hole for stiffer cornering?

Thanks

I reccomend starting with the end hole with the softest setting first. Once you get a feel for the new handling characteristics, you can make it stiffer if you need to.

I would like to add that even the softest setting will yield immediately noticeable difference.

Ok,i installed my bar today on my 67,it was alittle bit of a pain the ass but its in,the only question is how much do i adjust the end links?right now i have them all the way screwed till it stopped.

Thanks

So guys ride height is what the end links set?i have them all the way in is that where you guys set them too?


Thanks

Thanks

I adjusted the endlinks so the rear swaybar was parallel to the ground.

Adjusting so that the arms of the sway bar are parallel with the ground is correct. The rear hump should tilt down and be even with the bottom of the center section of the axle. The end links are adjustable since there are so many different ride heights out there. The kit should work with stock height to a 3 in drop.

ok cool,now you say ride height to 3" drop,i`m assuming screwing them in would drop the height correct?

Thanks

Screwing them together will shorten the end link to allow the bar to be parallel with up to a 3inch drop in ride height.

Dave, kinda simple question, maybe. Have a ProTour rear bar on order through SC&C, looking forward to getting this in the car. Will running the bar at the stiffest setting wear it out faster or make it more prone to stress failure?

Thats definately a good question.

Thanks

The bar will not 'wear out' as it is designed to handle the stresses seen in this application. The bushings may eventually wear but the bar will be fine. Our sway bars have a lifetime warranty if anything should happen.

This bar is awesome,its a huge difference than the Hotchkis that was on it before,i definately recommend it.

Thanks

The bar will actually be stressed more on the softer setting than it would on the stiffer setting.

Actually the softest setting stresses the bar the least as it generates lower forces overall.

to the guys that have the bar installed

Did the bar help with the handling of the corners?

Did the bar help with launching the car at the track?

from 1 to 10 (10 being excellent) how would you rate this bar's over all performance?

And How much does the bar weight?

The sway bar weighs about 8 lb. I developed this bar on my own 68 Chevelle which has had a lot of seat time. Compared to a stock style 1" sway bar that mounts to the control arms the ride quality and handling are much improved, especially on rough surfaces. THe winner of the autocross at this year's chevellabration was running our front and rear sway bars with SC&C's suspension.

Actually the softest setting stresses the bar the least as it generates lower forces overall.

I have to disagree... softest setting has the longest lever-arm, so the car's body will have more leverage over the lateral part of the bar, increasing torsional flex. This increase in the bar's flex, is what makes it softer...

Less stress on the mounting hardware and linkages, but more stress on the bar itself.

For me, I'd give it a "10" for cornering... I autocrossed all last year with no rear bar, so I was band-aiding everything with springs that were too stiff for my dampers, and too much air-pressure to try to get the car to rotate in the corners.

This year, with the Hellwig rear bar on the softest setting, I can run much softer rear springs, and can utilize the whole tire contact patch. :) I also stiffened up the front with a 1-1/8" 2nd Gen F-body front bar.

With the longer lever arm at the softest setting,the stress in the sway bar is reduced because the longer arm reduces the angle of twist for a given deflection and the reaction forces are lower. If the end of the bar is deflected 1" in both the soft (longer arm) and firm(shorter arm) settings, by geometry there will be a greater angle of twist with the shorter arm and higher forces generated.

I think your response above nails it. From an autocross view, it does make a lot sense to build in some articulation. But, from a drag race view, you want as little of this as you can get. I ended up using a Hellwig 1" solid factory mount style bar. Spring rate out back is either 143 rate or 167 rate. I need to try both, in my case, only desire to go around corners at normal street posted speed limits, surprisingly, swapping in the solid 1" bar didn't seem to make the ride any harsher. Guess each style has it's purpose.

any one??

I'm not much of a drag racer, but if I were using this bar for drag racing, I'd set it at the stiffest setting and maybe add some preload by adjusting the right side link longer than the left.

I'm an autocrosser, so I don't have my car set up to hook very well at the drag strip...

It will definitely help, but it's not quite as stiff as the "drag-race" bars on the market.

I might have missed it, but is there a recommended front bar to go with it? General cruising most of the time for now, some auto-x type stuff once the rest of the car comes together.

We have two front bars I reccomend.

55703 1-5/16 Tubular FSB This bar works well with stock front suspension geometry

55706 1-1/4" Tubular FSB This bar works best with tall spindles or tall ball joints.

Okay. Thanks. I'm going to be running tall ATS spindles with shockwaves.

I removed my stock style 1 inch bar and installed this hellwig bar last week. I have 3 inch exhaust all the way out the rear. My mufflers & hangers were far out of the way. I guess I got lucky, so that part was easy.
To make drilling holes easy for the frame mount easier:
I made a small metal plate with two 11/32 holes in it 1-3/4 apart. I bolted it into the existing 5/16 tapped hole and it made drilling the second hole in the right place "a snap".
I first drilled the hole to 11/32 . then I removed my template and opened both holes up to 13/32.
Every bolt & every piece was in the box and everything went together super smooth.
Directions were easy to follow.
Thanks to Dave for a well engineered kit.

Now I just need to work on my autocrossing skills.
Here it is being used at Goodguys Chicagoland on Sunday aug 14:http://www.youtube.com/user/tybotim#p/u/4/XvC0BeSaruM
Here's my "fail" from Friday. (I knew i was done after leaving the course so I was hot-dogging.)

That tempest or whatever it was looked like it was glued to the track. Pretty cool.

55703 1-5/16 Tubular FSB This bar works well with stock front suspension geometry

55706 1-1/4" Tubular FSB This bar works best with tall spindles or tall ball joints.

Dang! Will you please explain this? I JUST installed the 1-5/16 front bar and I have the AFX tall spindles on the way. Why is the smaller bar better for the tall spindles? Do I need to sell my 1-5/16 and order the 1-1/4? Will it really make a noticeable difference?

The tall spindles raise the roll center location and are usually used with aftermarket coil springs that have a higher spring rate than stock. These changes reduce the size of the sway bar required for best handling. You don't need to sell your 1-5/16" bar. I would drive the car and see how it handles. Worst case it will have a slight amount of understeer. You can always firm up your rear bar a little to balance it out.
