Detroit Locker & NoSPIN Assemblies — Traction Solutions

Trucks with open (conventional) differentials lose drive when a single wheel breaks traction. The Detroit Locker / Eaton Detroit NoSPIN® fixes that by automatically locking both axle shafts under load so engine torque reaches both wheels—then unlocking as needed to let the truck corner smoothly. No air lines, no switches, just proven mechanical traction.

Why Run a Detroit/NoSPIN

• Maximum traction: Both wheels drive on low-μ surfaces (mud, snow, gravel, job sites).
• Automatic operation: Locks on throttle, differentiates when coasting/turning.
• Heavy-duty build: Full-case, mechanical locker designed for commercial loads.
• Less downtime: Fewer external parts vs. air lockers; simple, reliable mechanism.

Common Applications

Line-haul tractors needing yard/site traction, vocational dump and mixer, municipal plow/salt, utility and forestry trucks, oilfield/service, and off-highway support vehicles.

Axle Coverage (Typical)

• Dana / Spicer: S135, S150, S110/S130; DS/RS404, 405, 454; 170/190 series
