Filthy Motorsports 2.5 Ton Rockwell Axle ARB Locker Installation Photos





















ARB Air Lockers use a pneumatically controlled locking mechanism to switch between an open carrier and a fully locked differential. Once installed, all it takes is the simple flip of a switch to go from an open differential that works well on the street to a spool that provides 100% traction to both wheels off-road.

Installation:
ARB lockers require no special tools or skills to install, apart from those necessary for fitting a standard differential. An ARB air compressor is the only additional thing you will need as each ARB locker comes complete with switches, solenoids, fittings, nylon air line, and even shims and bearings (if applicable).

Durability:
ARB Air Lockers are sold in over 80 countries and there are over 150,000 units currently in use worldwide in both military and civilian applications. The secret to their success and reliability is that each ARB locker is designed and tested beyond the breaking point of standard and aftermarket axles such that your axles will break before causing any damage to the air locker.

The ARB Air Locker uses an air controlled locking mechanism to engage and disengage the unit.

Design:
Each locker is machined from a solid piece of nodular iron and encases 4 pinion gears (twice as many as most OEM differentials) with unique geometry that make them up to 30% stronger than OEM gears. The side gears that transfer force to the axle shafts are made from the highest grade nickel alloy steel and are finished with an aerospace grade surface treatment. ARB's proprietary timed locking system prevents gear grinding during engagement and extends the life of the unit.



Compressors:
ARB Air Lockers require a pressurized air source to engage and disengage their locking mechanism and Filthy Motorsports has you covered with five ARB compressor options ranging from the small and compact ARB CKSA12 all the way up to the powerful and portable high capacity twin compressor ARB CKMPT12 kit.
