Powertrax Lock-Right -vs- No-Slip

[My65Stang]

I'm thinking of upgrading my 8" from an open diff. to a locking.

Is anyone out there using a Powertrax unit? I've read that the Lock-Right makes a clicking sound when going around corners. If this is true, how bad is it? I mean, is it worth the extra $200 to buy the No-Slip?

Is the cheaper one more for off-road trucks (who probably don't care about a little noise), and the better one for street use?

I could use some help.


Edit: I found this in the Powertrax Application Guide

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.

They will make a little noise when unlocking when cornering. Can't tell you about the new one. The tried and true Detroit Lockers made noise too, but they were almost bullet proof for a street / strip car. If your car is mainly driven on the street, a clutch style limited slip diff is the way to go. Currie makes a Traction Loc differential for the 8" that works real well.

I used to run a Powertrax unit in my 9" but the same unit was supposed to be able to fit into either 9 or 8.
Anyways, I would not recommend anything powertrax makes. When cornering the two hubs inside disengage and re-engage erratically and caused me to have more than a few spin outs. I took the unit apart and found broken springs that dampen the loading on the pinion shafts. I put it all back together and ran for a hundred or so miles and had the same problem again so I replaced with a posi. Saving to get a Tru trak from Eaton.

lock right lockers tend to wear out pretty fast when used other than off-road only as that is their intended purpose. I have a detroit locker in my bronco and it's tough, but if you accelerate around a corner it will lock the rear end... so in a car this might cause a spin out during hard driving, i'd go the posi route.
