ARB #RD121 - Toyota 8" IFS Air Locker - 30 spline axle - 3.73 & Down gear ratios

Installation of the ARB RD121 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 output or mini), the ARB #RD121 - Toyota 8" IFS 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 RD121 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.
