You need the most possible control, performance and traction whenever you take your new Jeep Wrangler onto the trails, and that means turning your open differential into a locked differential that controls both wheels with the flip of a single switch! Your JK's original differential is designed to let each wheel turn independently (4WD) and eliminate binding turning turns. When you go off-road, that feature can be a major dragon your JK's engine, leaving you with little to no traction when you need it most. Your all-new pneumatic locking differential uses air to lock both of the axle shafts. Your Air Locker is crafted from superior aircraft-grade materials to add extra strength and reliability to the mod. Be sure to pick up your Air Locker now from CJ's!
