ARB Differential Cover Heavy Duty Nodular Iron

The ARB heavy duty differential cover (also called a diff cover or axle cover) replaces the thin stamped-steel factory cover with a rugged cast high-tensile nodular iron cover. It is built to shield the differential, ring and pinion gears and carrier from rocks, ledges and other off-road hazards.

Key Features:

• High-tensile nodular iron construction, much stronger than a factory stamped cover
• Computer-optimized cross-brace design adds structural support to the housing. ARB says this also helps extend carrier bearing life.
• Recessed tensile cap screws help protect the hardware from obstacles
• Shape designed to help approach and departure angles
• Low-profile drain plug resists impact damage
• Neodymium magnets in the dipstick and plug collect fine metal particles from the gear oil
• Dipstick/filler cap lets you check and adjust the differential oil level
• Powder-coated and clear-coated finish helps resist rust and corrosion

A damaged factory cover can lose its sealing surface and let gear oil drain out. That can lead to overheating and ring and pinion damage. The ARB cover helps prevent this, so you can keep driving on the trail with more confidence. It is also backed by ARB's 3-year warranty.
