Don’t be fooled with cheap gear sets: Avoid expensive repairs by building your rig right the first time. Marlin has stood behind the quality of the Yukon name for over a decade. Do it right the first time with high quality Yukon Gears from Marlin Crawler. Yukon Gears are produced with state-of-the-art equipment and manufacturing techniques. They produce gear sets with a smooth finish that runs cooler and quieter than other aftermarket gears. Due to this excellent quality control, Yukon gears provide easy and consistent setups. We recommend using new bearings when setting up a R&P. 1986-1995 4cyl differentials require a new setup kit for installation.

Includes one ring & pinion set for 4cyl 8″ differential.

Note: V6 and High Pinion differentials are available and are an easy conversion. Converting to a 1986-1995 Turbo/V6 differential will provide larger bearings and a stronger 3rd member housing. But like the 4cyl 3rd member, it is limited by the standard rotation of the ring and pinion. Converting to a 1991-1997 FJ80 Land Cruiser front High Pinion 3rd member will provide larger bearings, a stronger housing and a reverse cut ring and pinion gear set. The high pinion provides increased front flange clearance, reduced front drive shaft angle, and it’s gear set is substantially stronger in the forward direction. Please follow these links for pricing and info: Turbo/V6 & High Pinion.

Includes one Yukon ring & pinion with larger 29-spline pinion diameter for increased strength. Please Note: 8″ Pinion Gears prior to 1996 were 27-spline. This product upgrades this smaller 27-spline to the stronger 29-spline, requiring a new 29-spline flange sold separately here.
