Product Details

The ARB RD189 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 axle shafts together, forcing both wheels to turn at the same speed and delivering 100% of available torque to both wheels. This ensures you maintain forward momentum even when one wheel loses traction completely.

Complete Air Locker Kit Includes:

  • Replacement locking differential assembly
  • Dash-mounted activation switch for on-demand control
  • Air compressor solenoid valve
  • Air line for pneumatic activation
  • Bulkhead fittings for secure installation

ARB Air Lockers are renowned as the world's premier differential locking system, trusted by serious off-road enthusiasts and professional expedition vehicles worldwide. Unlike limited-slip differentials or automatic lockers, the Air Locker gives you complete control—engage it when you need maximum traction, and drive normally when you don't. The pneumatic activation system is durable, reliable, and provides smooth engagement without the harsh clunking associated with mechanical lockers.

Ideal for rock crawling, mud bogging, sand driving, and any terrain where wheel slip is a concern. The RD189 Air Locker transforms your vehicle's capability, allowing you to tackle obstacles that would stop an open differential in its tracks.

Seems pretty legit. Low prices.

Fast shipping, packaged with care. Product was exactly what I expected.<br>Overall great experience!

Like that it hooked up with Amazon so I didn't have to re type info

Very pleased with the service and quick shipping. Checked out through Amazon payments without any issues. Item ordred was the Hella Supertone Horns. Arrived in original box and packaging. Will not hesitate to order from Autoplicity in the future

Super Easy Find what I NEEDED Plus at a Very Low Price AND ORDERING WAS EASY AND QUICK HOPE DELIVERY IS AS FAST AS ORDERING

We will see.

Shipped and received in quick fashion. Item arrived as expected. Would definitely buy from again!

Exceeded my expectations searching and ordering

Very easy to navigate web site. Received my order in excellent condition in a timely manner. Recommend Autoplicity as a company with which to conduct business.

Easy!!! Fast.... the items were fine but the packing suffered horribly in transit. The box was tattered and sagging but the contents had not gotten out.....yet. Other than that everything was swell.

fast transaction

Autoplicity is Awesome!!!!! I ordered a Aeromotive Stealth 340hp fuel pump for my 89 Supra Turbo. Not only did they have the best price on the part I ordered, the shipping was the fastest I've seen in a long time from any company. I ordered it on Wednesday, had it shipped to a freinds house where my car is and the part was there Friday morning. I was like DAMN!!!! That was fast I wasn't expecting it till Saturday or even Monday. Luckly my friend was off work that day so he could sign for it. With service like that I will definitely order from them again, even if the part cost a little more, cause I know I will get it ASAP!!!! On top of getting the awesome price, shipping, and customer service, now they are offering another $5.00 off my order. The only thing that could have been better is if they offer Military Discount which I forgot to ask about. Well kids the moral of the story is, that if you don't order from Autoplicity you are just plain DUMB!!!!!!

Awesome website with a wide selection of performance upgrades.

Great business to deal with! Notifies location an status of orders timely and efficiently
