Description

This Yukon Muscle Car Limited Slip & Re-Gear Kit is engineered to enhance traction and durability for GM 8.2" Buick/Olds/Pontiac differentials. It upgrades your existing differential with a Yukon Dura Grip Limited Slip Differential (LSD) and a new ring and pinion gear set, providing a 3.73 gear ratio and a 27-spline pinion gear. Included components comprise the Dura Grip positraction LSD (specified as 28 spline, though the pinion is 27 spline), a ring and pinion gear set, and all requisite bearings and installation hardware. This kit is compatible with a range of classic GM vehicles, including '64 to '72 Olds 442, '64 to '72 GTO, '67 to '72 Firebird, and '69 to '72 Trans Am models, as well as other hot-rodded vehicles equipped with the GM 8.2" Buick/Olds/Pontiac differential. The differential features a 10-bolt ring gear design.
