Product Details

The ARB RD139 Air Locker is a pneumatically-activated locking differential designed to deliver maximum traction in challenging off-road conditions. When engaged, the Air Locker locks both wheels on an axle together, forcing them to rotate at the same speed regardless of available traction. This ensures power is distributed evenly to both wheels, allowing you to maintain momentum through mud, sand, snow, and over obstacles where open differentials would leave you stranded.

Key Features:

  • On-demand activation via dashboard-mounted switch for seamless transition between locked and unlocked operation
  • Pneumatic locking mechanism provides 100% power distribution to both wheels when engaged
  • Functions as a standard open differential during normal driving for smooth handling and tire wear
  • Engineered and manufactured to OEM specifications for reliable performance
  • Complete kit includes replacement differential carrier, electronic activation switch, air solenoid valve, air line, and bulkhead fittings

The ARB Air Locker gives you the versatility to drive normally on pavement and highways, then instantly engage full traction when the terrain demands it. Simply flip the switch to activate the locker and flip it again to return to open differential operation. This makes the Air Locker ideal for daily drivers that see weekend trail use, as well as dedicated off-road vehicles.

Quick and Easy, Just like it should be.

Highly recommend

I ordered an Alternator, it arrived on Saturday via Federal Express. It fit and works perfectly! Very happy with my purchase!! Best prices and well worth the short wait. I'd have paid twice as much locally, for a far more inferior product.

Excellant

Don't know yet till I receive product

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.

Quick and efficient

Superb in every aspect, product, price, and shipping!!!!

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.

Easy and fast. Order arrived very fast. Thanks.
