Improves Vehicle Traction for Tough Off-Road Trails When tackling aggressive and uneven off-road trails, sometimes you need that extra boost of traction to push you over tough landscapes. ARB's Rear Air Locker is deigned to do just that as it provides 100% traction on demand without affecting on-road drivability or driveline wear. It works by locking the gears along the axle to improve your vehicle's traction even on wet or slick roads. Moreover, the patented timed locking mechanism offers high strength and ultra fast un-locking, so you can keep moving along the trail without compromise. This incredibly simple yet effective design employs minimal moving parts in order to provide consistent performance and maximum reliability. High-Quality Construction & Warranty Info Constructed from high-strength steel, the ARB Rear M220 32 Spline Air Locker was built for maximum strength and long-lasting functionality. To endure the harshness of forgiving terrain, this air locker differential also sports a 2-piece design with expertly forged gears that will provide consistent performance over any application. Moreover, the steel reinforced, elastomer bonded annular seal was designed to handle the most extreme temperatures on earth. This entire unit was also torture-tested to ensure this differential won't let you down. Professional installation is recommended for this unit, but if you do plan to complete this at home, all if the necessary hardware and mounting instructions are included. Best of all, this kit is backed by a 5-Year Limited Warranty to help protect your investment.
