Specs. This Alloy USA rear kit complete with an ARB air locker allows your Jeep to utilize every ounce of power for off-roading and rock crawling. The shafts are made from 4140 Chromoly, heat treated twice, and then induction hardened for up to 35 percent more strength than your YJ's stock shafts. Alloy USA cold rolls the splines for enhanced durability. The ARB locker is constructed out of aerospace grade steel with forged gears. With this locker, you can worry less about carrying momentum through the trails and instead rely on your Jeep's torque. The shafts have 30 splines and feature a 5 by 4.5 inch lug pattern. Alloy USA protects your investment with a ten year warranty.

Application. This kit is for use with 1987 - 1989 YJs equipped with the non c-clip Dana 35 axle. This kit comes with the seals and wheel studs necessary for installation. The ARB locker requires a 3.54 and up carrier.
