vince Posted February 24, 2015 Share Posted February 24, 2015 I'm a little unsure if this will work. Only because Im not sure what axel splines I have.The rear end is a 12 bolt and I already picked up some 3:31 gears.The add states Eaton Style maybe it's not an Eaton, the guy has 100% feed back so that a good thing. What do you think? http://www.ebay.com/itm/GM-12-Bolt-CAR-3-Series-Posi-30-Spline-8-875-Limited-Slip-Rearend-NEW-/391042885490?pt=Motors_Car_Truck_Parts_Accessories&hash=item5b0bf8e772&vxp=mtr Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted February 24, 2015 Share Posted February 24, 2015 30 spline should be stock axles, call and talk to them Quote Link to comment Share on other sites More sharing options...
Vinniepooh Posted February 24, 2015 Share Posted February 24, 2015 $100 Cheaper than an actual Eaton from Jegs. Quote Link to comment Share on other sites More sharing options...

vince Posted February 24, 2015 Author Share Posted February 24, 2015 30 Spline is what I was looking for, I'll give them a call and ask a few questions. Quote Link to comment Share on other sites More sharing options...
Murphy Posted February 24, 2015 Share Posted February 24, 2015 Hey Vince, That's a Yukon posi unit, yes it will work. I'm talking with a guy here who rebuilds differentials for a living and he really likes them! I'm going with the same unit and probably a 3.42 gear if I can't find the 3.31 at a reasonable price.......... Quote Link to comment Share on other sites More sharing options...
