Yukon Grizzly Locker for GM & Chrysler 11.5" with 38 spline axles
Yukon Grizzly Locker for GM & Chrysler 11.5" with 38 spline axles
Fitment:
The Yukon Grizzly Locker is a robust and advanced mechanical positive-locking differential designed for rock crawling, serious trail running, off-road racing, and drag racing. Its casing, gears, and advanced gear tooth design significantly enhance traction and performance. The unit provides 100% power to both tires while allowing for disengagement during turns. The patented design includes innovations that make it tougher than competitors, such as larger inner clutch teeth with a greater radius at the base, offering up to 350% more strength compared to back-cut designs. These larger teeth also resist breakage from shock-loading or catastrophic axle failure. It is a serious piece mechanical engineering for demanding driving conditions.
Fits GM and Chrysler 11.5" with 38 spline axles
Patented internal design reduces common locker failures
8620 internals for added strength
Assembled in the USA
Technical Notes
Factory spindles will need to be bored out with tool part number YT H32 to accept the 38 spline axles this locker takes.
