Truck Differentials and Differential Carriers

If you're serious about traction off the line and through corners, a mechanical locker transforms your rear differential from a limiting factor into a performance asset. The Detroit Locker delivers positive lock-to-lock engagement without the delayed...

If you're running a Ford 8.8 rear end and want predictable, aggressive power delivery without electronic complexity, a Detroit Locker is the mechanical solution that separates serious racers from the rest. This 31-spline unit delivers full lock...

A locking differential transforms your Dana 35 rear axle from a power-splitting liability into a torque-vectoring asset, delivering consistent traction to both wheels under acceleration and cornering. If you're serious about drag racing, off-roading, or...

The Detroit Truetrac is a helical-gear limited-slip differential that delivers consistent, predictable power delivery without the noise and maintenance demands of traditional clutch-style units. For street and strip applications alike, it provides...

The Detroit Truetrac is a helical-gear limited-slip differential engineered to maintain traction under acceleration while allowing smooth cornering without bind or chatter. If you're running a GM 10-bolt and need predictable power delivery without the...

A limited-slip differential is essential for consistent traction off the line and through corners, especially if you're running your GM 8.5 on the track or in competitive driving. The Eaton Posi eliminates the power-loss inefficiency of an open...

If you're running a GM 8.5 10-bolt rear end and want predictable traction without the complexity of a full spool, the Eaton Posi limited-slip differential is the straightforward answer. This unit locks both wheels under load to eliminate inside-wheel...

A Detroit Locker transforms your Ford 9-inch differential from a power-splitting liability into a predictable, mechanical advantage on the track or trail. By eliminating wheel slip under acceleration, you'll gain consistent traction and faster corner...

Factory open differentials sacrifice traction for simplicity—costing you consistency on the track and control on the street. The Duragrip Differential transforms your GM 8.5/8.6 rear end into a true limited-slip unit, delivering improved power delivery...

The Detroit Truetrac transforms your Dana 44 differential into a precision traction tool, delivering consistent power delivery without the maintenance demands of traditional limited-slip designs. Whether you're tackling technical off-road terrain or...

The Detroit Locker is engineered for drivers who demand maximum traction and predictable handling under acceleration. Unlike passive differentials that allow wheel slip and power loss, this mechanical locker keeps both rear wheels turning together,...
