Look up the username 69boo307
I'm pretty sure he did this swap and made a feedback/results post somewhere on here.
I did a search but couldnt find it.

The only issue I have with the "truck arm" is exhaust routing. Kinda tough to get them out the back.

Thanks guys :D . It may actually go as fast as it looks one day, if I ever get my new motor done. :cool:

mister_n20, it's been discussed at length here, but if you have some specific questions just shoot me an email.
Yes exhaust routing is an issue, forget 'over the axle'. I don't mind exiting in front of the axle though. I have a cheap exhaust on at the moment, I plan on a much nicer setup when the new motor is done, exiting further back at the rear wheels.

Brian,

Have you driven the car much with the Truck Arms??? But you went from "stock" OLD suspension straight to the Truckarms, right???

I have never heard any "Real" testing or data about if the setup really is significantly better than a Modified A-body setup...

Only info I have heard was mostly from the company or employees... Nothing ever "really" compares the two...

I would like to see a magazine do an actual test... Maybe start with a stock Chevelle and baseline it, Then rebuild it with stiffer bushings (but not too stiff on those upper rear arms), springs, tires, etc... And then take the same car and add the Truck Arm and test again...

An Apples-to-Apples test, one setup to another with NO other changes (no front geometry changes, same tires, same driver,etc)...

I've put about 5,000 miles on mine so far. I went from the original stock suspension to the truckarm kit, yes.

I think one of the mag's did do a 'before/after' test, there are some videos on the HTH site from it. They put the kit on a chevelle and tested 1/4 mile times and I think a slalom course with before/after results, keeping everything else the same including some crappy tires.

I wish I could just give you a ride in my car, it's a completely different car than it used to be. The truckarm has an advantage in some circumstances such as bumpy/rough pavement, and would probably do better in a really tight course than a car with stock style suspension. It launches really smooth and straight at the drag strip. It has a different ride quality than the 4-link too, but ride quality is a subjective matter. Part of the 'feel' of the truckarm setup is due to the fact that you don't need to run a rear sway bar and can use the small factory front sway bar. This lets the springs/shocks do more of the work, and you get a smoother ride with better response on rough surfaces. With a stock style suspension you're probably going to need some beefy swaybars to keep body roll in check.

I'm sure one could build an A-body with a stock style suspension that would perform as well, the truckarm car would probably get it done a little more 'comfortably' if that makes sense.

I can tell you this, I've pretty much beaten the crap out of my car, as best i could with the little 307 under the hood, and I have yet to make the car 'push' or oversteer, even deliberately trying to do so in an empty parking lot. I also have yet to induce any sideways slide, again even trying to find the limits of the tires. Thus far I'm limited by my stock steering ratio and my lack of harnesses to keep myself seated in the car, the car's grip exceed both. Keep in mind though, I'm running high performance 275/40/ZR17 tires, I have a tubular front setup with an aggressive alignment, at leats for the street
(-.7 camber), and every bushing and suspension piece on the car is brand new. The HTH kits come with a very sweet spring/shock combo, which probably has as much to do with the improvement as the truckarms themselves do. My point is I did alot more than just add a truckarm kit, so it's hard to say what improvement that alone has made.


Another anecdote, I have a friend with a '99 camaro that loves to road race and has done many track days and road race events. He runs Yoko A032 road race tires on the street. I followed him to the dragstrip, and there are a couple of good turns and a cloverleaf exit where we always like to to test each other's 'balls'. To both our extreme surprise, Big Green hung right there with him through a cloverleaf and a 90 degree right turn.

Anyway, I'm not really giving you any concrete or quantitative information there...suffice it to say I'm happy with my car and it gets the job done, but I don't make any claim that what I have is the best possible setup. Everyone that rides in it is very impressed at the ride quality. I'm really more proud of my brake setup than my suspension setup, the C5/hydroboost brake setup is AWSOME. It will literally lift you out of the seat and make you nauseated under a full-on panic stop.
