Product Details

The ARB RD100 Air Locker is a premium selectable locking differential designed to provide maximum traction when you need it most. As the world's leading traction aid, ARB Air Lockers give you the confidence to tackle challenging terrain while maintaining normal driving characteristics on the street.

How It Works:

Unlike traditional limited-slip differentials, the ARB Air Locker allows you to engage 100% positive traction on demand with the flip of a switch. Compressed air activates the locking mechanism, forcing both wheels to turn together for maximum grip in mud, sand, snow, and rock. When unlocked, the differential operates as an open carrier for smooth, quiet on-road performance.

Complete Kit Includes:

  • Replacement differential carrier assembly with pneumatic locking mechanism
  • In-cab activation switch for driver control
  • Air compressor solenoid valve for precise engagement
  • Air line kit with bulkhead fittings for clean installation
  • All necessary hardware and installation instructions

ARB Air Lockers are engineered for durability and reliability in the most demanding off-road conditions. The proven design has made ARB the preferred choice for serious four-wheel drive enthusiasts, professional off-roaders, and expedition vehicles worldwide.

Finally found the part I was looking for at a reasonable price! Also, I called the customer support line to ask a question about the part, and they told me exactly what I needed to know!

Im satisfied with your assistant

Wonderful and fast

.

Very simple and easy

Fast shipping. Good price.

was exactly the part advertised and worked perfectly.

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

The delivery service was total mess the boxes were damaged and one of the nuts was missing .

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.
