Detroit Locker Truetrac Limited Slip Differential GM

The Detroit Locker Truetrac is a helical gear limited slip differential (LSD) built for GM applications. It replaces an open differential to send torque to the wheel with more traction. This gives you better grip in daily driving, towing, performance driving, off-road use and wet or slippery conditions.

Key Features:

• Gear-driven design: Helical gears split torque between the wheels. The Truetrac does not rely on clutch packs or cones that wear out.
• Smooth, quiet operation: It is a fully automatic unit. It engages and releases progressively, so there is no clutch chatter or harsh lock-up in turns.
• Maintenance free: There are no clutch plates or springs to adjust or replace. It also does not need friction-modifier additives in the gear oil.
• Improved traction: It helps reduce inside-wheel spin when accelerating out of corners or on loose or uneven surfaces.
• Durable construction: Detroit Locker (Eaton) builds it with precision-machined gears and a strong housing for long service life.
• Bolt-in installation: It replaces the factory differential carrier assembly. Proper gear setup is still important during installation.

Detroit Locker is a respected name in traction products, and Eaton has engineered its differentials for decades. The Truetrac is a popular upgrade for street, strip, towing and trail vehicles. Also known as a Torsen-style helical gear limited slip or posi differential, it is available in multiple configurations to suit different GM axle applications.
