Yukon Gear Dura Grip Limited Slip Positraction Unit For gm 8.5"/8.6" Differential With 30 Spline AXLe, 2.73-And-Up Ratio, Ydggm8.5-3-30-1

Well built. Works great. Installed in my truck for towing and in-the-woods hauling capabilities, replacing a stock open carrier. No issues, and I have put about 200 miles on it since the install (don't drive that truck much). No abnormal noises.

Muy satisfecho, calidad, precio y todo en tiempo

Used on a custom build called the creamsicle .. it’s a truck.. worked great!

I use this unit on a 1968 Camaro 12 bolt rear end. It came complete well-made machine surfaces everything fit as designed. I used the factory Yukon additive. I have 6000 miles under the rear end with a 327 manual transmission and both tires spin when power applied no slippage. Going forward I would not look for a used GM unit and just use a Yukon much simpler. It is well built and works well. I did buy the wrong unit because they have three models for different gearing and it was an easy exchange. Great customer service.

Better traction and no noticeable noise. Big difference over and open diff.
