The ARB Air Locker RD244 adds true selectable locking to the front Dana M200 (29-spline) axle in the non-Rubicon Jeep Wrangler JL. Sport, Sport S and Sahara models leave the factory with open front differentials — this Air Locker gives them on-demand 100% lock for climbing and off-camber terrain, then unlocks to drive like stock on the road.
Designed for 3.45 and numerically lower ring-and-pinion ratios, ARB's forged four-pinion centre is built to take the added stress of bigger tyres. Air-operated engagement is instant and repeatable, and the differential behaves as fully open whenever the locker is switched off.
