Description:

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.

Yukon Gear & Axle Dura Grip Positraction Titan 08 Finnally

Yes Yukon finally made a positraction for us Titan owners and not cost over a $1000. Bucks And this works great for us that have 2 wheel drive before 09 and have no locker system build in our truck from factory. I have haul 4 hay rolls on my trailer each 800 to 1000 lbs with no spinning just both wheels digging in the dirt roads. When taking the corners I don't hear any clicking sounds like some of the other lockers This is by far the best unit for the money AutoAnything BrucesTitan08

Dura grip review

this is what my 04 Silverado needed, it actually will get a wheel and not just one... cool, did not fool around. had a professional install it who is very familiar with this product. He asked what I paid for it and when I told him, he assured me that I got a great deal.
