Detroit Truetrac - GM 8.5/8.6 10-Bolt 30-Splin

The Detroit Truetrac - GM 8.5/8.6 10-Bolt 30-Spline differential carrier is designed to enhance the rear-end performance of GM vehicles. This product is ideal for truck and muscle car enthusiasts looking for improved traction without the noise and complexity associated with locking differentials. It is a perfect upgrade for those who want to maximize their vehicle's performance on both the street and the track.

This differential carrier replaces the factory open differential with a helical-gear limited-slip design, which maintains smooth on-pavement manners while providing aggressive traction during acceleration and cornering. The Truetrac utilizes precision-cut spiral gears that automatically distribute torque to the wheel with better traction as load increases. Its all-gear construction is maintenance-free, eliminating the need for periodic maintenance and fluid additive tuning.

Street enthusiasts, circle-track racers, and daily-driver truck owners will benefit most from the Truetrac's performance enhancements. This carrier is compatible with OEM GM axle shafts and installs directly into existing 8.5 or 8.6-inch housings without modification. With its straightforward installation process, experienced builders can upgrade their differential function in under two hours.
