Description

The kit is designed to fit GM 8.2” differentials and features a 25 spline pinion gear with a 4.11 gear ratio. The ring gear is a 10-bolt configuration, and it comes with 2.25" axle bearings (part number AK 1563). This re-gear kit is suitable for a range of classic GM vehicles, including the '64 to '72 Chevelle, '67 to '70 Camaro, and '64 to '72 Nova. It is also compatible with any vehicle that has been "hot-rodded" with a GM 8.2” differential, making it a versatile option for muscle car enthusiasts. Installation of this kit requires specialized knowledge and tools for proper differential setup. It is recommended to consult with a professional mechanic or a drivetrain specialist to ensure correct installation and optimal performance. The kit includes all the components necessary for the gear ratio change, eliminating the need for separate purchases of installation parts.
