Description

The Zumbrota Drivetrain YG T8-488-29 is a high-performance ring and pinion gear set engineered by Yukon Gear and Axle for Toyota 8" differentials. Yukon's commitment to quality is evident in their use of advanced design and heat-treating techniques, coupled with leading-edge quality testing. This meticulous process ensures that the structure and surface finish of each gear set meet the highest standards. The 4.88 ratio is ideal for optimizing traction performance, whether you've upgraded to larger tires or increased horsepower. This specific gear set is designed for Toyota 8" differentials and features a 29-spline pinion. It is crucial to verify your pinion spline count before purchase. The installation requires the use of pinion nut part number YSPPN-024. The Zumbrota Drivetrain YG T8-488-29 is compatible with 1979-1985 Toyota Pickup and 4Runner models, as well as 1975-1990 Landcruiser vehicles. Yukon offers an optional Y.E.S. Plan warranty, a lifetime, no-questions-asked protection plan for your gear set.
