A: The Auburn Gear Max Lock will fit a GM10 bolt 28 spline front end on a 1979 GM ½ ton.

A: No this will not fit.

A: Hello It only works on the 98 and older Sterlings with the single pin carrier. 99 and up they went to a tri-y style pin with 3 spider gears. I Lock-Right had a number but they never did make it. Thanks

A: Hello Rattler In 2006 they changed the inner dimensions of the carrier and side gears on the Dana 30. I don't know of any of this type of locker that fits the 2006 and newer Dana 30 axles. The only way I have seen it done is replacing the carrier with part number D/S706008x and install the locker in this carrier. http://www.4wheelparts.com/Drivetrain-Differential/Dana-30-Open-Differential-Carrier-Case.aspx?t_c=12&t_s=237&t_pt=5589&t_pn=D/S706008X Thanks

A: Hello Matt They work great on the street since they are a limited slip in the unlocked mode. When you flip the switch then it is locked up like spool both wheels locked together. Thanks

A: Hello Joe The 12 bolt axles have 30 splines.

A: Hello To install the locker in the Dana 30 front end it has to be torn down all the way to the carrier coming out. To get the carrier pin out the ring gear needs to come off the carrier. The labor cost would be 400.00 to install plus the price of the locker and fluid.
