Product Details

The ARB RD114 Air Locker is a premium locking differential designed to provide maximum traction in the most challenging off-road conditions. As the world's leading traction aid, ARB Air Lockers deliver on-demand four-wheel drive performance by locking both wheels on an axle together, ensuring power is distributed evenly regardless of available traction.

Complete Air Locker Kit Includes:

  • Replacement locking differential assembly
  • Dash-mounted activation switch for cab control
  • Air compressor solenoid valve
  • High-pressure air line for reliable operation
  • Bulkhead fittings for secure installation

Unlike limited-slip or automatic locking differentials, the ARB Air Locker gives you complete control—engage it when you need maximum traction in mud, sand, rock, or snow, then disengage for normal street driving. The pneumatic activation system ensures smooth, reliable engagement without the harshness or driveline stress associated with mechanical lockers.

Engineered and manufactured to ARB's exacting standards, the RD114 Air Locker delivers the traction advantage that has made ARB the choice of serious off-road enthusiasts, expedition travelers, and competitive rock crawlers worldwide.

Good products, good price!

Got what I needed no issues

Seamless service and fast delivery, even to Hawaii. Shipping costs were very reasonable unlike other sites that charge an arm and a leg.

Great service,received in two days

good

I appreciate getting namebrand parts at a good price.

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.

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 found Autoplicity on a well known online vendor and the experiance was excellent so now I just go straight to autoplicity.com directly my last order (17805) was for some parts for my very modifide Jeep and two things stood out, the price and shipping, both were top shelf and above my expectations. Now when I need parts I check autoplicity.com first. They are my #1 now.<br>

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