ARB Differential Cover for Jeep Wrangler JL

The ARB Competition Differential Cover (also called a diff cover or differential housing cover) is a heavy-duty replacement cover built to protect your axle's differential and ring and pinion gears from rocks, ledges and other trail hazards. ARB's Air Locker engineers developed the range for hard off-road use and competition use.

Key Features:

• Nodular iron construction: High-tensile nodular iron shields the differential and the ring and pinion set from impacts.
• Cross-brace truss design: A computer-optimized internal cross-brace adds rigidity to the whole axle assembly.
• Corrosion-resistant finish: A durable powder coat finish stands up to harsh conditions.
• Magnetic drain and fill plugs: Strong neodymium magnets collect metallic wear particles from the gear oil. They also let you check for signs of internal wear.
• Adjustable oil level: The dipstick and filler cap design lets you set the differential oil level to suit high driveline angles.
• Improved clearance: The angled, low-profile exterior helps approach and departure angles. Recessed hardware reduces the risk of snagging on obstacles.

This is a bolt-on upgrade for your axle. ARB notes that its covers suit the most common axle applications, and some installations may need minor clearance work. The cover adds strength, supports bearing alignment and helps extend ring and pinion life on trails.
