ARB Differential Covers

ARB Diff Covers

ARB’s nodular iron Differential Covers have been engineered to protect the differential and ring & pinion from off-road hazards.

Features:

  • Computer optimized cross brace design increases the structural rigidity of the whole axle
  • Additional housing strength helps keep the ring & pinion gears meshing on the flat faces of the teeth, greatly increasing ring & pinion life and overall maximum load strength
  • Top quality, high power neodymium magnets are used in both the drain plug and the dipstick to collect metallic wear particles
  • Magnet location in the end of the dipstick allows the oil to be checked for tell-tale signs of internal damage
  • Prolonged carrier bearing life due to extra support to the bearing alignment
  • Approach/departure angle optimized by angled exterior surfaces
  • Unique dipstick/filler cap design allows differential oil level to be adjusted for customized high driveline angles

Available for:

  • Dana 35
  • Dana 44 (except Aluminum)
  • Dana 50/60
  • Chrysler 8.25″
  • Ford 8.8″
  • GM 10-Bolt

ARB’s Diff Cover will protect your differential against the hazards of impact during competition or extreme off road use and are designed to counteract flexing of the axle assembly When off road, it is inevitable that obstacles will be encountered that could potentially inflict expensive damage on your differential. To prevent this, ARB’s Differential Cover is available for a range of vehicle models, and has been specifically engineered to protect the differential and ring & pinion set from any off road hazards.

  • High tensile nodular iron structure protects the differential and ring & pinion set from off road obstacles
  • Computer optimized cross brace design increases the structural rigidity of the whole axle
  • Approach/departure angle optimized by angled exterior surface
  • Prolonged carrier bearing life due to extra support to the bearing alignment.
  • Top quality, high power neodymium magnets are used in both the drain plug and the dipstick to collect any metallic particles in the oil. This makes the dipstick an easy location to be checked for tell-tale signs of internal damage or water contamination without the need to drain the oil.

ARB Air Lockers

ARB Air Locker - Selectable locking differentials

ARB Air Locker – Air Operated Locking Differentials for 100% Traction!

ARB Air Lockers were created to provide 100% traction on demand, without sacrificing any of your vehicle’s highway driving performance, these locking differentials employ a 12 volt air compressor designed to activate (and deactivate) a solid and durable locking mechanism inside the differential. This gives you the traction you need, when you need it, all at the flick of a switch, all within the safety and comfort of the driver’s seat.

When activated, the Air Locker prevents the differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like conventional “open” differentials.

The experts at West Coast Differentials are well qualified and have many years of experience dealing with ARB Air Lockers. We can help you decide if an Air Locker is right for your application and make sure you get the correct unit for your vehicle. Our large inventory means most applications are IN-STOCK and READY TO SHIP same day!

We also stock ARB Air Locker replacement parts, installation components and ARB Air Compressors.

See our ARB Air Compressors & Accessories page for more information about ARB Air Compressors and Accessories .

 Differential Bearing Puller Kit from ARB Air LockerDifferential Bearing Puller

ARB’s new Differential Bearing Puller Kit is a professional tool that no automotive differential installer should be without.

As original equipment differential bearings have become more expensive and often difficult to source, it has been increasingly important to attempt to remove the original bearing without causing any damage to it. This specialty tool offers a unique way of removing a differential carrier bearing without the need to get access under the seating face of the bearing cone. The ARB Differential Bearing Puller Features:- Quickly and easily removes the carrier bearings from most automotive differentials- Removes without the same level of risk of carrier bearing damage and Air Locker seal surface damage damage associated with most commercially available bearing pullers.

– Able to remove many bearings that standard bearing pullers cannot

– Works with most models of ARB Air Locker and OEM differential centers

– Comes in a durable carry case with a dedicated powder coated parts tray for easy storage and transport

Nissan Titan Locking Differentials

Posted by zenxeon on
West Coast Differentials has three different locking differentials available for the Nissan Titan Dana 44 Rear axle (M226-32 Spline). These options include the Dana Spicer original factory electric locking differential, Eaton’s Detroit Truetrac and the ARB Air Locker. Both the factory electric locker and the ARB Air Locker are open differentials that can be fully locked by the flip of a switch. The Detroit Truetrac is a smooth-operating limited slip. Axle modifications may be required to install a Truetrac in models equipped with the factory electric locker. These models have unequal axle lengths due to an offset cross-pin. For more information, check out our Application Guide for Nissan, or call our sales department for assistance.
