The OX Locker is built tough for the serious Jeep off-road enthusiast. The precision machined forged differential cover completely eliminates the need for a skid plate. It's unique 4 pin design provides the most strength available in any locker available! The locker engagement system is constructed of billet aluminum and steel components with a sure shift action which allows for easy disengagement for highway driving and tight turns off road, and simple engagement for tough terrain and rockcrawling. Never worry about on-board air to power your lockers again. All this adds up to make OX Lockers the strongest locker on the market, whether you drive a Jeep or not! Each Locker listed below includes: Locker, Cover and Shifter. (Cable not included.)
