They perform like an open differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant.

So Far Great

Summit RacingSummit Racing Verified Purchase

Put it in 2 weeks ago. I am putting out 465 rwhp and no problems. It has no noise in turns. Locks up tight. Great Price for a posi unit. Lower rating on ease of installation has nothing to do with the unit but the installation into the GM Differential. Will buy again for next project.

Best posi

Replaced auburn cone style cause could only hit 2.1 60 foots. Back in the 1.8s works great but need special bearings for older housings. Did have to reset backlash so doesn't hurt to have a shim kit ready.
