Crawling rocks and hitting rough terrain trails, the last thing you want to worry about is if your truck's tires have enough traction to get you in and out. With an ARB Air Locker, you no longer have to worry. They utilize 12-volt air compressors to activate and deactivate a locking mechanism within the differential, so you can get full traction on any terrain with the flip of a switch. It is an on-board system so you can deactivate it without leaving the truck's cab. Many ARB compressors are compatible with the Air Locker system, and some are also able to air tires and other compressor tools. The Air Locker is easy to install, as it does not require any special tools. Kits typically include the necessary parts for installation, including the locking differential, switch, carrier bearings, and air line. For a strong and durable option to gain traction while taking your vehicle off road, an ARB Air Locker from the large inventory available on eBay is a great option for many different 4-wheel-drive vehicles.Shop the large inventory of car and truck parts and other car and truck differentials and parts!
