Detroit Locker - Dana 35 27-Spline

The Detroit Locker - Dana 35 27-Spline is a mechanical locking differential designed for serious off-road enthusiasts and daily drivers who demand maximum traction in challenging terrain. Built for Dana 35 axle housings with 27-spline axle shafts, this locker automatically engages both wheels on an axle simultaneously, eliminating wheel spin and delivering power to whichever tire maintains grip. Whether you're navigating rocky mountain passes, muddy trails, or sand dunes, the Detroit Locker transforms how your vehicle handles low-traction situations.

This locker operates via an automatic clutch mechanism that locks when torque is applied and unlocks during turns to allow normal differential action—essential for street driving and highway travel. The 27-spline configuration matches factory Dana 35 applications, ensuring proper fit without modifications to your existing axle assembly. Detroit Locker's stamped-steel construction and precision-engineered internals provide reliability in extreme conditions, with minimal maintenance required after installation. Unlike welded differentials, this unit delivers lock-up performance without sacrificing on-pavement manners or requiring driver input.

Mechanics and off-road builders favor the Detroit Locker for Jeep Wranglers, Ford Broncos, Dodge Dakotas, and other light trucks equipped with Dana 35 rear axles. It's the ideal upgrade for vehicles that see both highway commuting and weekend trail work, where a full-time locker would compromise steering response and tire wear. Installation requires axle removal and carrier replacement—a straightforward job for experienced technicians but best performed by a qualified shop to ensure proper bearing preload and backlash settings. At 17.25 lbs, this unit integrates seamlessly into your existing Dana 35 housing without additional weight penalties.
