Product Installation Instructions
Get your F-250 / F-350 locked and ready to rock with a Yukon Grizzly locker, the ultimate in mechanical locking differentials for off-road and drag racing. Grizzly Lockers provide 100% straight line power to both tires, while still allowing for disengagement while negotiating turns. Patented internal design reduces common locker failures with 8620 internals for added strength. As the name implies, the Grizzly full time auto locker is a beast off road but has compromised manners on the street.
