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 does NOT use the factory thrust washers. Failure to remove the factory thrust washers will cause the unit to act improperly and can cause damage to the unit.
