The RD132 adds selectable locking to the matching 30-spline Toyota 8-inch live-axle differential. It helps both wheels contribute on loose or uneven ground, giving you a useful traction upgrade for your Hilux, Prado, Land Cruiser or FJ Cruiser when fitted with this axle.
SKU: XADLRD132
On uneven ground, an open differential can let one wheel spin while the other has grip available. Engaging the Air Locker makes both wheels on that axle turn at the same speed, helping you tackle the section with controlled progress. Tyres and terrain still determine the grip available; the locker helps you use it.
This is the adjuster-nut-preloaded Toyota 8-inch live-axle carrier with a 10-bolt ring gear. Shim-adjusted rear axles use RD133; Toyota 8-inch IFS front differentials use separate codes. Older 45 mm bearing applications require the specified replacement bearings. For FJ Cruiser rear fitment, this is the 2006-2009 non-factory-locker axle; later rear axles differ.
Disengaged, it operates as an open differential so the wheels can turn at different speeds in a corner. Engage it before a difficult low-traction section, with the wheels turning at the same speed. Switch it off when normal differential action is needed, particularly on firm surfaces or tight turns.
The ARB CKMA12 single onboard compressor can operate one or two correctly installed Air Lockers. Add the ARB pump-up hose kit if you also want to inflate your tyres with it. The compressor and inflation kit are separate purchases.
If you regularly air down for trails, the ARB CKMTA12 twin onboard compressor offers more airflow for tyre inflation. Its Air Locker connection uses the separate 171503 manifold kit. Choose the twin for the extra inflation capability; the CKMA12 already has capacity for two lockers.
A differential specialist sets the bearing preload, gear backlash and air sealing together, so your locker and existing gearset run correctly. Carrier bearings are selected separately for the installation. The air line is routed clear of heat and moving parts, then the locking operation is checked before the vehicle returns to use.

When one wheel would otherwise spin, engaging the locker lets both wheels on that axle turn together. That helps the wheel with grip contribute to your progress on loose climbs, ruts and uneven tracks.
Switched off, it works as an open differential for normal cornering. Keep it disengaged on firm surfaces where the tyres cannot slip.
Toyota 8-inch live axle, adjuster-nut preload with 30-spline shafts. Match the full axle and ring-gear specification above, including any bearing or shaft-retention requirements.
No. The CKMA12 single onboard compressor can operate one or two correctly installed Air Lockers. The CKMTA12 twin is a useful upgrade if you also want more airflow for tyre inflation; use its separate 171503 manifold for locker connections.
One RD132 Air Locker differential assembly. The compressor is separate. Carrier bearings are selected separately for the installation.
The installation includes bearing preload, gear backlash, air sealing and engagement checks. We recommend a differential specialist so the locker and your gearset are set up together.
