Yukon Grizzly Locker GM & Dodge 11.5" AAM with 38 Spline Axles

The Yukon Grizzly Locker is the ultimate in locking differentials for street, off-road, & drag racing. Grizzly Lockers provide 100% power to both tires, while still allowing for disengagement while negotiating turns. The factory spindles will need to be machined in order to accept the axles this locker uses. The Yukon Grizzly locker is a mechanical locking differential. It features a forged case and 8620 internals for maximum strength. It's patented design reduces common locker failures. All units assembled in the USA! All Grizzly Lockers are backed by the best warranty in the business! Yukon covers the replacement unit and covers any collaterally damaged parts and associated labor, up to $2,000!
