ARB Air Locker Differential, Dana 44 Rear, 35 Spline, 3.92 and Up Ratio for Jeep Wrangler (1997-2006)

This is an air-actuated locking differential for the rear Dana 44 axle in 1997-2006 Jeep Wranglers. It suits 35-spline, 1.50 in. shafts with gear ratios of 3.92 and numerically higher. It drives like an open diff on the road and locks on command when the trail gets ugly.

Why it works
Traction on demandLock both rear wheels together when you need it and leave it open the rest of the time, with no change to road manners.
Few moving partsA two-piece design keeps the internals simple, which is the point of a locker you rely on far from the road.
Cab-side controlThe activation switch lets you lock and unlock without leaving the driver's seat.
Built for temperature extremesThe reinforced elastomer-bonded seal is designed to cope with very hot and very cold conditions.
