Overview

The ARB RD261 Air Locker Differential Kit is a premium traction aid for off-road driving, featuring a two-piece design, forged gears for strength, and a five-year, unlimited mileage warranty. It provides maximum traction to both wheels, overcoming the limitations of standard or limited-slip differentials in challenging terrains (rock, clay, snow, sand, mud). The kit includes installation hardware and instructions, is compatible with ARB Air Compressors, and requires drilling for the air line. Differential setup is necessary, though existing ring and pinion parts are typically reused. Manufactured in Australia, it offers race-proven technology and global support.
