Yukon Gear & Axle Dura Grip Limited Slip Differential Positraction, 30 Spline, 3.73-Up Ratios, 12 Bolt GM Axle, YDGGM12T-4-30-1

Can’t beat the price and the quality highly recommended

Great deal and saved over $200 working like a champ.

Great posi, out of the box it looked great and had good looking parts. assembly went great. Gear pattern very close to stock carrier with stock shim thickness. Spider gears wear good but leave some to be desired in terms of pattern worn on them.This is a different posi compred to the stock chevy/GMC versions, clutches only used vs the original G80 with centrifugal weight system + clutches. The drive feel is a bit different but not too annoying. Get an extra set of clutches yukon (composite) or eaton (carbon fiber), youll need them within 6 months of light wheeling. Eaton set bites harder and last wayyy longer.

Whines going down the road and grinds turning, don’t even bother with customer service it took me four days to get in contact and then they just told me to change the fluid even though I used exactly what they recommended.

I got a great deal on this Yukon posi, it came down to 606. bucks black Friday, for my 1971 Chevy K10,it's a shame Yukon company wouldn't include the Yukon posi-track additive that is required, some guys might cheap out on the additive and burn up the clutches, SHAME ON YOU YUKON.I'll be installing it soon.

Carrier showed up in a yukon box. Missing factory packaging. Carrier is filthy dirty with cardboard dust. I am not impressed.
