Truck Differentials and Differential Carriers

The Detroit Truetrac is a helical-gear limited-slip differential that delivers consistent power distribution to both wheels without the maintenance demands of clutch-style units. If you're running a Dana 44 and want predictable traction during cornering...

If you're running a Ford 10.25-inch rear axle and need consistent power delivery to both wheels without the slip of an open differential, the Grizzly Locker delivers mechanical lock-up exactly when you need it. This 35-spline unit engages under load to...

Limited-slip differentials are essential for serious track work and high-performance street applications—they keep power flowing to both wheels even when one loses traction, eliminating the dead-wheel spin that costs you seconds and consistency. The...

A quality limited-slip differential is the foundation of predictable, controllable power delivery—especially when you're pushing your GM 12-bolt to its limits. The Duragrip Posi design locks and unlocks seamlessly to maintain traction during acceleration...

If you're running a Ford 9-inch differential in a high-performance or racing application, you need a locking mechanism that delivers consistent traction without compromising drivability. The Duragrip Trac-Loc positraction differential combines aggressive...

The Ford 8.8 differential is the backbone of any serious rear-end setup, but a factory open differential will kill your acceleration off the line and compromise cornering grip. The Duragrip Differential locks power to both wheels when you need it most,...

When you're pushing serious power through a GM 12-bolt, wheel hop and axle wind-up will kill your 60-foot times and compromise traction off the line. The GRIP LS delivers the locking authority you need to transfer peak horsepower to the pavement without...

If you're running a GM 10-bolt rear axle, this 30-spline GRIP LS axle shaft delivers the strength and reliability you need for consistent power delivery under load. Built from high-grade steel and engineered to precise OEM specifications, it's the direct...

A quality differential is the foundation of reliable power transfer and traction control in any performance build. The GRIP LS delivers superior strength and precision fitment for GM 10-bolt applications, giving you the durability and consistency needed...

A bulletproof axle shaft is the foundation of reliable rear-end performance, and the GRIP LS Ford 9in 31 Spline delivers the strength you need for high-powered applications. Built from quality steel with precision spline engagement, this shaft handles...

A solid axle shaft is fundamental to reliable power delivery, and this GRIP LS 28-spline unit delivers the strength needed for high-torque applications without compromise. Whether you're building a dedicated track car or upgrading a street machine, a...

A limited-slip differential is essential for serious track work and high-performance driving, where wheel spin during cornering costs you lap time and consistency. The GRIP PRO Posi Unit delivers progressive locking action that keeps both rear wheels...

A limited-slip differential is essential for serious track work and high-performance street driving, transforming how your Ford 8-inch rear end handles cornering and acceleration. The GRIP PRO Posi Unit eliminates wheel spin through mechanical advantage,...

If you're running a GM 12-bolt rear end and want to eliminate wheel spin off the line, this 30-spline traction system delivers the mechanical advantage you need for consistent power transfer. Built with no-slip functionality, it maximizes grip during...

The Detroit Truetrac is a helical limited-slip differential that delivers superior traction and corner exit acceleration without the maintenance demands of locking differentials. If you're running a Dana 44 and need predictable power delivery on both...

The Detroit Truetrac is a helical limited-slip differential engineered to maintain traction without the maintenance burden of traditional clutch-type designs. By distributing torque intelligently across both wheels during acceleration and cornering, it...

The Detroit Truetrac is a helical limited-slip differential engineered to deliver seamless power distribution without the maintenance headaches of clutch-type designs. By maintaining traction during hard cornering and acceleration, it eliminates...

The Detroit Truetrac is a helical-gear limited-slip differential that delivers aggressive locking action without the maintenance headaches of clutch-based designs. For Dana 30 equipped vehicles—whether you're hitting the track or tackling technical...

The Detroit Truetrac is a helical limited-slip differential engineered to deliver maximum traction without the maintenance demands of traditional clutch-type designs. If you're running a GM 8.5-inch rear axle and need predictable power delivery under...

If you're running a Ford 8.8 rear axle in a performance application, an open differential will leave power on the table under acceleration and cornering. The Eaton Posi limited-slip differential locks up to 80% during hard turns, sending power to both...
