ARB Rear Diff Cover for Land Rover Series and Defender with Salisbury Rear Axle

Defender – Rear Salisbury axles
High tensile solid nodular iron structure (tougher and harder than solid carbon steel) protects the differential and ring & pinion set from the obstacle impact hazards of competition rock crawling, or extreme off road trails.
Computer optimized cross brace design adds more than 1300 Nm/deg (960ft-lb) of torsional rigidity to the entire axle assembly. This increased flexural strength in the housing helps keep the ring & pinion gears meshing on the flat faces of the teeth, which greatly increases ring & pinion life and overall maximum load strength.
Carrier bearing life is prolonged, especially on high output vehicles, by the improved support given to the bearing alignment.
Low-profile shape of the outside surface helps maximise the running gear clearance around the cover.
Maximized approach/ departure angled exterior surfaces help to minimise rock/ obstacle hang-ups.
High tensile cap screws (supplied with the kit) are recessed into the cover to protect them from contact with obstacles which might damage or loosen them.
Cover is powder coated, CNC machined, then clear coated for a durable, professional, long lasting finish, hardware is zinc plated.
Low profile drain plug design resists damage from obstacles.
Combination of the high filler point and dipstick allows the oil to be checked for water contamination without having to drain the oil.
Magnet location in the end of the dipstick allows the oil to be checked for tell-tale signs of internal damage.
Top quality, high power neodymium magnets are used in both the drain plug and the dipstick to collect metallic wear particles as the vehicle moves.
