Product Details

The ARB RD181 Air Locker is a pneumatically-activated locking differential designed to provide 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 equally to both wheels, allowing you to maintain forward momentum through mud, sand, rock, and other extreme terrain where open differentials would cause wheel spin.

Key Features:

  • Pneumatic activation system for instant on-demand engagement and disengagement
  • 100% lock-up when engaged for maximum traction in extreme conditions
  • Functions as a standard open differential when unlocked for normal on-road driving
  • Proven ARB design used by off-road enthusiasts and professionals worldwide
  • Complete kit includes replacement differential housing, dash-mounted activation switch, solenoid valve, air line, and bulkhead fittings

ARB Air Lockers represent the gold standard in selectable differential technology, offering the perfect balance between everyday drivability and extreme off-road capability. The RD181 provides the mechanical strength and reliability needed for serious four-wheel drive applications while maintaining the versatility to switch between locked and unlocked modes at the flip of a switch.

I don need to comment

Everything has been pretty easy

Great service

so far so good

first time ive order from here and my experience was great! shipping was crazy fast. and they had the best price shipped on the 2jz arp head stud set i could find. also how on their site they actually list if they have the part in stock and how many which is very helpful. ive payed for parts to find out the vender didn't even have them available. which lead to more down time. and we all hate down time :)

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

Best price on the internet. A lot cheaper than amazon, so I was pretty surprised.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.

Excellent customer service. Treated me very well. Issued a refund, no problem. Thank you!!
