Detroit Locker - GM 10.5 14-Bolt

The Detroit Locker for GM 10.5 14-Bolt differentials is purpose-built for serious off-road and performance driving where maximum traction and wheel speed control matter. Designed for GM's venerable 14-bolt full-float axle housings, this locker transforms an open differential into a true locking differential capable of automatically engaging both wheels when one loses grip.

Whether you're hauling heavy loads across uneven terrain, navigating rocky trails, or maximizing acceleration on the street, the Detroit Locker delivers predictable, mechanical traction without electronics or driver intervention. This locker operates on a spring-loaded, cam-and-pawl mechanism that engages clutch plates when the rotational speed differential between wheels exceeds design limits. Unlike viscous or electronic alternatives, the Detroit Locker provides immediate, consistent lock-up without fade—critical when sustained traction is non-negotiable.

Truck owners, off-road enthusiasts, and performance builders running GM 10.5 14-bolt rear or transfer case differentials benefit most from this locker's no-compromise engagement. It excels in various driving conditions, ensuring that both wheels maintain traction for improved performance. Installation requires removing the factory differential carrier and replacing it with the locker assembly, making it compatible with existing ring and pinion gears in your current setup.
