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.
Technical Notes:This unit is drilled for 1/2" ring gear bolts. This unit is not compatible with 2012 and newer JK's with an automatic transmission.
