Product Details

The ARB RD140 Air Locker is the world's premier traction aid, designed to conquer the most challenging terrain by providing 100% traction on demand. When activated, this locking differential sends equal power to both wheels on an axle, ensuring you keep moving even when one wheel loses traction in mud, snow, sand, or rock crawling conditions.

Key Features:

  • On-demand differential locking—engage and disengage from inside your vehicle
  • Pneumatic activation system provides instant, reliable locking
  • Maintains factory-like performance during normal driving with locker disengaged
  • Forged and CNC-machined components for maximum strength and durability
  • Compatible with ABS and traction control systems

Complete Kit Includes:

  • Air Locker differential carrier assembly
  • In-cab activation switch with indicator light
  • Air compressor solenoid valve
  • Air line and bulkhead fittings for installation
  • All necessary hardware for a complete installation

ARB Air Lockers are the trusted choice of serious off-road enthusiasts, expedition travelers, and professional rock crawlers worldwide. Unlike limited-slip or automatic locking differentials, the Air Locker gives you full control—lock it when you need maximum traction, unlock it for smooth on-road driving and tight turning.

Autoplicity had the best price by far on the item I was looking for. I paid for 2nd day air shipping and my order total was still less expensive than ordering from any other merchant. My item arrived the day after I ordered it. I will definitely buy from them in the future.

Best price fast shipping. will deffinitly order again

Best Price on the Net for K&N System for my 2012 HEMI RAM. My Order 18270 is shipping today and I can't wait to get it installed!

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

Best price on the Internet and quick shipping

Very fast and easy ordering system. My order was shipped the next day.

......

So far so good! Just ordered the parts I needed for my car which I've been trying to find EVERYWHERE without success, until I arrived at autoplicity. Great price, and with a lifetime warranty I'm assuming great quality. I have faith that when the product arrives I will be highly satisfied.
