Detroit Truetrac - GM 7.5 26-Spline

The Detroit Truetrac GM 7.5 26-Spline differential carrier is designed for drivers seeking a balance between stock open differentials and full locking units. This product is particularly suited for light-duty to mid-duty trucks and SUVs equipped with GM's 7.5-inch rear axle platform, making it an excellent choice for off-road enthusiasts and performance-minded owners.

The Truetrac utilizes a clutch-pack bias system that automatically transfers torque to the wheel with better grip when traction is lost, returning to open-differential behavior during normal cornering. This design enhances traction in various conditions such as snow, gravel, and mud without the harshness associated with full-spool lockers. Weighing 21.4 pounds and engineered to OEM tolerances, it is a straightforward bolt-in upgrade requiring only carrier removal and reinstallation.

Off-road builders and mechanics favor the Truetrac for truck builds that target moderate terrain without the need for full lockers. It is compatible with Chevy K5 Blazers, GMC Suburbans, and pickup trucks featuring the GM corporate 7.5 axle, ensuring improved cornering grip and drivability on asphalt.
