Hello, I have a 1991 Chevrolet Suburban V2500, I believe the front axle is the GM 10 bolt 8.5" 30 spline. Will this E-Locker work in the front? and will it require the special LM102949 / LM102911 bearings, Also will it handle 37" tires?

Asked by Pannhead from Raleigh NC on

Hello Yes that is the correct unit for the GM 10 bolt with 30 spline axles. It does work front or rear on the 10 bolt. It will need the bearings also since the made the bearing journal larger. I have a large number of customers running 37 and 38's with no problem with the locker. Thanks

Hi, Will this one fit in my 2006 Chevrolet Tahoe Z71 rear axle? The G80 axles break a lot and I'm looking for improvement. Thanks

Asked by Roland from on

Hello Roland Yes this is a great upgrade over the stock G80 differential. It is a direct bolt in replacement in your Z71. Thanks

From what year to what year in a Chevy or GMC truck will this Eaton 19659-1 GM 8.5 / GM 8.6 10 bolt 30 spline E-Locker fit ?

Asked by JR from Weslaco, Texas on

Hello It will work on the 1988 1500's all the way up to the 2013 models. The only difference will be the install kit. There are different carrier bearings for the 98 and older and 99 and newer.
