It doesn't matter if you're a fan of the General or the Blue Oval, any motorhead who wants traction goes for the race-proven 4-clutch posi-traction designed by GM back in the days of classic American muscle. There was simply no other model as reliable or rebuildable. Now, you can get this classic design with the Yukon Dura Grip Positraction Unit.
By transferring torque to the tire with the most traction, the Yukon duragrip posi delivers super aggressive, yet smooth, controllable traction. Yukon starts with the classic GM 4-clutch and spring design, then makes it better. Using state-of-the-art equipment and manufacturing techniques, the Yukon dura grip differential uses a nodular case, forged 4320 steel gears and composite clutches for high performance and long life. And, select units feature larger bearing journals and heavy-duty carrier bearings & races for maximum strength.
To make rebuilding easy, Yukon also uses off-the-shelf internals. They offer the Yukon Powr-LOK for all popular GM and Ford rear end designs, with more choices for select vehicles. What's more, Yukon backs your Dura Grip Positraction Unit with a 1-year warranty.
