AMC 20 ARB® #RD60
Air Locker Features

The ARB AMC 20 air locker RD186 for your 29 spline axle for 3.08 & up gear ratios, can instantly lock differentials and allow you to tackle the toughest off-road terrain. The world's best traction aid, ARB Air Lockers keep you moving in all conditions.

Air Lockers from ARB are currently available in over 100 configurations to suit a wide range of off-road and 4x4 vehicles from around the world. Because the AMC 20 ARB® #RD186 air locker is only engaged when needed, it can be installed in BOTH the front and rear axles, with separate switches independently controlling the RD60 air locker from within the off-road truck or vehicle.

ARB® Air Locking Differentials For Competition/Off-Road/Rock Climbing »

Installation of the ARB RD60 air locker should be performed by a qualified differential technician, although no special tools or skills are required apart from those necessary for fitting a standard differential. When installed with an ARB air compressor (high putput or mini), the ARB #RD186 - AMC 20 locker system is supplied as a complete kit which contains all of the parts necessary for proper installation, including industrial grade control switches, air lines and fittings. ARB offers two compressor models suitable for RD60 air locker operation (high output air compressor or mini air compressor). A dedicated air activation system is available which is extremely durable and compact. Alternatively a larger compressor can be specified, which is also perfect for inflating tires, air mattresses and a host of other applications where compressed air is required.
