The Yukon Grizzly Locker is the ultimate in mechanical locking differentials for street, off-road, and drag racing. Grizzly Lockers provide 100% power to both tires, while still allowing for disengagement while negotiating turns.
- 8620 internals for added strength
- Assembled in the USA
- Fits GM and Chrysler 11.5″ with 38 spline axles
- Patented internal design reduces common locker failures
Technical Notes: Factory spindles will need to be bored out with tool part number YT H32 in order to accept the 38 spline axles this locker takes.
