For Use With Toyota 8″ IFS Clamshell differential with 30 Spline Axles and 3.73 And Down Factory Gears
Usually all models that came with a manual transmission used 3.73- factory gear ratios, but you must check before ordering
Factory R&P may use either RD111 or RD121 depending on ratio. All known aftermarket R&P sets suit RD121.
If you are re-gearing, check with the gear manufacturer for which Air Locker to order
Full vehicle fitment list is further down in the main description, includes 4Runner, Tacoma, FJ Cruiser, GX470, GX460
At the flick of a dash-mounted switch, compressed air is delivered to the seal housing assembly via a nylon air line.
Instantaneously go from an open differential to a fully locked differential at the flick of a switch for maximum traction
Requires an Air Compressor for operation, Sold Separately
Why do they use air? Air is used on every semi truck on the road to reliably operate their brakes through solenoids, and ARB uses the same technology. When installed correctly, it’s ultra-reliable!!
The ARB Air Locker is a pneumatic locking differential that uses air to facilitate the locking of both axles. This action converts your differential from a conventional open to a full spool type axle supplying 100% power to both wheels to keep you going through the worst terrain.
This Air Locker kit includes the full differential, instruction booklet, airline, fittings, switch and cover, and necessary seals. When combined with an Air Compressor and the original differential, you’ll have everything you need as far as parts go.

It’s recommended that a qualified differential mechanic do the installation for proper setup

ARB RD121 Front Air Locker Toyota Lexus 8″ IFS 30 Spline 3.73 and down numerically is made for a wide variety of Toyota and Lexus vehicles that use the 8″ front differential.

The ARB Toyota 8″ IFS air locker RD121 for your 30 spline axle for 3.73 & down 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 4×4 vehicles from around the world. Because the Toyota 8″ IFS ARB RD121 air locker is only engaged when needed, it can be installed in BOTH the front and rear axles, with separate switches independently controlling the RD121 air locker from within the off-road truck or vehicle.

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 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.
