Thanks Chris,

I just bought 2 !!!!

I don't think those are the Powertrax units that you want. They are the Lock Right units for, mainly, 4x4 and mud use. The "Performance Locker" is the one for HiPo use in cars.

They make two versions, one is designed for "off road" (the one called "Lock Right") and is noisy on the street. The other is quiet (no loud clicks when turning) is called the "No Slip" can be seen here. http://www.powertrax.com/noslip.htm

The Performance Locker is the same as the Lock Right name. Marketed as "Performance" in auto applications and Lock Right for off road applications.

Just in case, I just sent an E-mail to Richmond (they bought out Powertrax) requesting the Part Numbers for the "Performance Locker" for both a 12-bolt and the 8.5" 10 bolt...the two that I bought were #1910 and #1920.

Powertrax used to claim 600 HP capability in the "Performance Locker" and did not recommend the No-Slip in anything more than a warmed over small block for racing. It was on their website 3 about years ago. I can't find this written anywhere anymore.

The one in my Monte has endured 5 years of abuse so far.

Chris, thanks for the heads-up. Chris, Tom, my '65 has a 12 bolt and will be getting a fairly mild 496 within the next couple of weeks. Do you think #1910 would work OK in my '65 Chevelle, given that it will be driven regularly, (including by my girl friend in her 40 mile round trip commute)?

I can live with minor clunking and such during turns, but will it last a few years at 5-10K miles per year? Also, would you run synthetic gear oil with this? Are any additives needed? TIA

Wes,

You should have no problem at all. I have about 8,000 street miles on mine. I love mine. Watch getting on the gas on long turns like a highway ramp, it will try to straight because it will try to lock the axles.

as for the oil, Do Not Use Synthethic. I tried it twice and drained it out immediately.

At that price in Jegs, I bought a spare for a 12-bolt and one for my Buick.

Wes,I put 10K miles on mine,and I bought it used!

Would these work well in a bracket car, I'll be runnuing a 9 inch and for 175.00 bucks that would be sweet.

I did read his response and he didn't mention bracket racing, that's why I ask.

Chris, Tom, thanks for the reply. I just ordered one for the Malibu.

I came across an unused set of Powertrax springs the other day in my tool box. :confused:
I believe they are yours...

I installed the Lock Right unit in my 64 SS, last year, into the original 8.2" 10 bolt. The performance is outstanding. Here is a quote from the Powertrax site on what this unit is used for - "An excellent choice for off-road vehicle applications, performance enthusiasts also began using the Lock-Right Locker to satisfy their extreme traction requirements for racing, hot-rods and muscle cars." It is called the "Original" Locker because it is an older design and noisier than the No Slip unit, but with a warmed over 355 and Flowmasters who's hears it anyway?

Are they on sale right now or something? If they are I'd better get one now... Usually I see them for like $350 and around there...

KS64SS,

Is the orginal a 28 spline or 30 spline for 64? I would like to order one and with my exhaust, I won't notice the difference. Thanks

- John

I just searched Jegs for Powertrax and the other lock unit is over two hundred dollars more. These are the same thing but different part numbers? Mark

I read the description on the web site. I am confused by it. Does this unit lock both wheels together? Similiar to a spool/posi unit? The discription made it sound like it didn't, that it gave power to the wheel with the most traction.

It's not like a spool, a spool keeps both locked all the time... Not good for parts...

A posi has some slip. then lockes, right? So then how close to like a posi is it. Does a posi have both wheels locked when driving down the road?
I am saying a posi, mine has clutches in it, that is a posi correct.

Enganeer - I believe the 64's had both a 28 spline (8.2" ring gear, 10 bolt cover) and a 30 spline (8.875" ring gear, 12 bolt cover) but most of the ones I have come across were of the 8.2" rear ends. The Lock Right works just as good as a spool when going in a straight line, it occasionally chirps the tires when making a tight turn. It unlocks the axles like a clutch type unit does, but powertrax uses a ratchet style approach, with specially designed teeth that slip over each other when the wheels turn different speeds, thus creating the "clicking noise" everyone hears when turning. Sometimes sounds like you're crunching rocks in your differential and others barely make any noise at all. The metal is supposed to be as strong or stronger than titanium, so wear is not much of a concern. Axles locked by a Posi-type, on the other hand, can become unlocked from each other if one of the tires gets better traction.
Sorry so long smile.gif

bolted in the PowerTrax on friday and raced on Saturday. Bitchin! Ran a best of 12.30 in the 1/4 mile. We used a Lock Right #1910 and it was easy to install.

So this replaces the posi unit?

NO, it does not replace a "posi". It will only fit in an "OPEN" carrier. If you have a posi and wish to change to this, you'll need to also change the carrier.

When you mash the gas both wheels are locked like a spool and there isn't anything but locked axles. when you gas it going around a turn be careful...coast if you can.

It is sometimes funny when backing up to a gas pump, the looks on some faces like the rear is going to fall out is pretty funny.

It can be an uneasy feeling hearing the strange noises, but after about 6 months you get used to it.

The original style or Lock right or Performance Locker is MUCH stronger than the newer and more expensive quiet unit mostly because it is simpler.

My good friend runs a '78 Caprice with 3.73's, a power bench seat, and a ZZ4 motor in the 13.60's and has the newer quiet style. You would never know it was there and has been in for 3 Full once a week every week racing seasons and at least 20,000 miles.

To answer an earlier question, Yes I bracket race with it and my current powertrax unit has approximately 150 12 second 1/4 miles, 160 11 second 1/4 miles and 46 10 second 1/4 miles on it.

My car is set up to run 10.60's to 10.90's. I am not sure of the limitations of the units. As I said earlier, powertrax claimed good to 600 HP. I am somewhere around there.

I would like to know if there is anyone out there on TC using one with more Torque than I am pushing through mine.

I read your post all the time Mr.4 Speed(Chris), why don't you try a different gear, at least the 3:73, and see how your times are, maybe you can get a little more ,at least at the eighth mile.I truly admire what you run with the gears you got !!!

Thanks for the compliments Scott.My "local" track (129 miles away) will be open the 1st week of April,and I intend to and will better that 12.99 best with 2.73's,and depending on what I get out of it,I have 3.31's to put in.Right now,I'm expecting high 12.8X's to low 12.9X's with 2.73's
I'm out to get the most from my ride before I change anything. graemlins/thumbsup.gif

Tom, not trying to argue or anything, just trying to clarify. Are you absolutely certain the Lock Right and the Performance Locker are the same units? I know PowerTrax, on their old web site (gone since the introduction of the newest unit), said the Lock Right was designed for 4 wheeling, and such, and the Performance Locker was designed for HiPo use. They had different part numbers, literature, and boxes. I supose all that could have been hype to get more money for the Performance unit. I know Jegs use to carry both. I dug out the box, the part numbers is VX194A, similiar to the Lock Right number of 1940 for the 8.2 28 spline. I only ask since I'd hate to see people putting a weaker unit in when they thought they were getting a stronger unit, if there is a difference.


KS64SS Said "The metal is supposed to be as strong or stronger than titanium, ...".
I don't know what they are made of but I did a Google search on "Zytanium" (what the box says it is made of) and had hits that only referred to PowerTrax units (and one on a LaCross stick), no metallurgy hits. I suspect it is chrome moly and "Zytanium" is advertising hype.

I found the following info on the Powertrax units, pasted directly form the powertrax site - "What is the difference between the No-Slip Traction System and the Lock-Right Locker?
While both products offer maximum traction, full wheel differentiation, and easy installation, each product has features and benefits that meet the needs of different customers. The No-Slip Traction System uses SynTRAC technology and is the latest design in traction adding differentials. It provides the maximum traction of a locking differential combined with the smooth and quiet operation of a limited-slip device. The Lock-Right Locker is our original product line that offers extreme value in a traction-adding differential. The Lock-Right provides maximum traction, but a light clicking noise can be heard when turning as the Lock-Right gears allow for wheel differentiation. On some vehicles the engine noise will overcome the clicking noise. For additional details on the No-Slip Traction System and the Lock-Right Locker, please see their corresponding web page."

Pat K - here is what powertrax claims on the metalurgy - "Only ultra strength material is used which is 67% stronger than titanium." Still doesn't say what the metal is though.

I have a buddy that is running low 10's on slicks, in a 67 Chevelle SS, with nitrous, using the original lock right locker, it's been working great for several years now. I think powertrax just pushes the No-Slip line more now because it is the latest in design, quieter but not stronger.

Actually, I wasn't taking about "No Slip Traction System". I was referring to the differences between the Performance Locker and the Lock Right. Maybe they have dropped the Performance Locker, I don't know. Or, as Tom said, they are the same unit and they no longer sell it as the Performance Locker.

My Performance Locker has held up for many years of drag racing use. I just know than when I was researching at it, the PowerTrax site recommended it over the Lock Right unit for racing and HiPo street use.

67% stronger is a bunch. I'm surprised that no aircraft or other uses (other than the Lacross stick) showed up. Seems like a natural for rods and other highly stressed parts.

OK guys help me out i want order one for my 70 chevelle , can someone list what i need to know when ordering
PART NUMBER and MODEL :confused:
i have a 10 bolt 8.2 28 spline axle rearend /open
this a stock 70 chevelle rear
and price should it be
i have been trying to ID my rearend so far everone has said it should be a 10 bolt 8.2 with a open carrier, 28 spline axles ,but how can i know for sure , i would hate to order parts for the wrong rear thanks

Part #Mor-8300 from summit is what i'm running in mine , sqeals the tires when you make even a very slow turn , but works great!! http://store.summitracing.com/partdetail.asp?part=MOR%2D83000 If thats what ya'll talking about

Pat,

I hear you 100% I have the VX191A in my car too.
Since Richmond purchased Powertrax they use both the Lock Right and Performance Locker names interchangably.

In searching for the positive answer to your (and mine) concern I sent Richmond an E-mail Friday (1/30) morning asking for the part number of the "Performance Locker" for a 12 bolt. In the meantime I ordered a 1910 from Jegs and it should be here this Tuesday or Wed.

The results of inspection and info from Richmond should hopefully totally clarify the question/concern you have brought up.

I found These in Summit

PWT-VX191A LOCK RIGHT GM 12 BOLT OPEN $315.95 Not Available

PWT-1910 DIFFERENTIAL LOCKER $199.50 Not
Available

Now check out this webpage

With all of the discussion, am I right in assuming that the "Lock Right" unit shown in the Jeg's link is the same just a little noisier than the newer "No Slip" ?

OK guys help me out i want order one for my 70 chevelle , can someone list what i need to know when ordering
PART NUMBER and MODEL

Then to answer Robert G's question - is he looking at the p/n 754-1920 ??

I need one too ! :D

Tom

Tom, the newer unit is the "No Slip Traction System".

The big question is whether or not the model sold as the "Lock Right" Locker model 1910 for the 12-bolt is the same as the unit sold as the Performance Locker part number VX191A a few years ago.

Hopefully I will get some info out of Richmond on Monday.

Thanks, Tom, I'm certainly interested in what you find out.

For others, as Tom said above, we are talking about 3 PowerTrax units, the original Lock Right, the Performance Locker, and the No-slip Traction System. The question Tom and I are discussing is whether the Lock Right and the Performance Locker are the same unit. The No-Slip Traction System is the newest unit available. I personally do not know anything about the No-Slip. It appears the Performance Locker is no longer available. So, really, I quess most of this discussion is moot.

I know man $$$$$$$$$, it don't grow on trees. I went with the bigger valves and man what a difference, Suck and Blow, thats all they(our motors) do. Good Luck Man !!

Does anyone use the no slip version? Their site says it is quiet with no ratcheting noise. Is this right?
