Overview:

The ARB Differential Cover is a rugged, high-quality protective component designed specifically for the rear M200 axle found in Jeep Wrangler models from 2018 to 2023 and Jeep Gladiator models from 2020. Off-road enthusiasts understand the risks posed by rocks, debris, and other trail hazards that can cause costly damage to the differential housing and internal components. This ARB cover offers a robust defense against such impacts, ensuring the longevity and reliability of your vehicle’s drivetrain.

Engineered for serious off-road use, the cover not only shields the differential but also supports the ring and pinion gears, helping to maintain optimal alignment and performance under extreme conditions. Its durable construction and thoughtful design make it an essential upgrade for Jeep owners who demand both protection and peace of mind on challenging terrain.

Key Features:

ARB’s differential cover incorporates advanced engineering and premium materials to deliver superior protection and durability. Key features include:

• Constructed from high tensile nodular iron for exceptional strength and impact resistance
• Recessed tensile cap screws to prevent damage from obstacles encountered off-road
• Low profile drain plug designed to resist damage and facilitate easy fluid changes
• Computer-optimized cross-brace design that enhances housing rigidity and prolongs carrier bearing life
• Integrated magnet location at the end of the dipstick with strong neodymium magnets to capture metal particles
• Powder-coated finish for corrosion resistance and long-lasting appearance
• Optimized approach and departure angles to maintain off-road capability without compromising protection
• Additional housing strength to withstand heavy impacts and rough terrain

Construction & Design:

The ARB differential cover is crafted from high tensile nodular iron, a material known for its excellent toughness and durability under stress. This choice of material ensures the cover can absorb and deflect impacts from rocks and trail debris that would otherwise damage the differential housing. The cover’s design includes a computer-optimized cross-brace that reinforces the structure, reducing flex and extending the life of internal components such as the carrier bearings.

Attention to detail is evident in the recessed cap screws, which minimize the risk of snagging or damage during off-road excursions. The low profile drain plug is strategically placed and protected to allow for convenient maintenance without compromising durability. A powder-coated finish provides resistance against rust and corrosion, ensuring the cover maintains its protective qualities and appearance over time.
