Whether narrowing a rear axle housing for bigger tires or just building a new housing for your street car, you will need housing ends to complete the project. You could re-use the old housing ends but most of the time they are either too rusty or damaged from the removal process. Competition Engineering's Forged Rear Housing Ends are offered in five popular styles, each CAD designed to ensure a proper fit. They are forged from mild steel to allow for ease of welding and then fully machined on CNC equipment. A black oxide coating protects them from rust and allows them to be welded without major grinding.

The locker sensor in Wrangler JL and Gladiator Rubicons have started to become problematic. When they fail, it usually starts out as a blinking locker indicator on the dash, which then ends up in a "service axle locker" message and the lockers will no longer engage. The repair would normally be to replace the sensor or the locker assembly, but they are not available, so the entire axle assembly needs replaced. Developed in a partnership with Americas Most Wanted 4X4, Z Automotive Jeep JL/JT Z-Locker OEM controller harnesses provide a simple fix for faulty OEM axle locker. Each harness will bypass the problematic sensor, allowing the locker to operate without the position sensor and provide the proper feedback to the Jeep's computers to keep the system operational without any errors or warnings. You get fully functioning lockers with no side effects. Installation is simple and they will not harm the Jeep's computers as they use the same signaling that it expects from the sensor. The connectors are the same ones used by Jeep and are watertight.

When off-road, encountering obstacles and hazards that could inflict expensive damage to your differential is inevitable. ARB differential covers are made from high-tensile strength nodular iron (tougher and harder than carbon steel); they are engineered to protect the differential and ring and pinion from off-road hazards. Available for a select line of differentials, they are offered in red or black powdercoated finishes. Features of ARB differential covers include: * Computer-optimized, cross brace design increases the structural rigidity of the entire axle * Helps keep the ring and pinion gears meshing on the flat faces of the teeth--greatly increasing ring and pinion life and overall strength * Top-quality, rare earth magnets on both the drain plug and dipstick collect metallic particles * Dipstick magnet allows the oil to be checked for tell-tale signs of internal damage * Prolonged carrier bearing life (especially on high-output vehicles) from improved support of bearing alignment * Approach/departure angles optimized by angled exterior surfaces that minimize hang-ups * Unique dipstick/filler cap design allows differential oil level to be adjusted for rotated differential housings * Low-profile drain plug resists damage from obstacles * High-strength cap screws (included) are recessed into the cover for impact protection
