Eaton Detroit Truetrac Differential 30 Spline 1.29in Axle Shaft Diameter 3.54-5.29 Ratio

Upgrade your drivetrain with the Eaton Detroit Truetrac Differential 30 Spline 1.29in Axle Shaft Diameter 3.54-5.29 Ratio, a proven traction solution for drivers who want stronger performance without giving up everyday drivability. Built for dependable operation in changing road and trail conditions, this differential is a smart upgrade for off-road builds, tow rigs, work trucks, and daily-driven 4x4s.

The Eaton Detroit Truetrac uses a gear-driven limited-slip design to automatically transfer torque to the wheel with more traction. Unlike a traditional locking differential, it delivers smooth and quiet operation while helping improve control on loose dirt, gravel, mud, wet pavement, and uneven terrain. That makes it a great option for drivers who want added capability without the abrupt engagement of a full locker.

Designed for 30 spline applications with a 1.29-inch axle shaft diameter and 3.54-5.29 gear ratios, this differential is built for durability, strength, and long-term performance. It is an excellent choice for enthusiasts looking to improve traction, stability, and confidence in both on-road and off-road environments.
