Description
The ARB RD132 Air Locker Differential is engineered to provide maximum traction for Toyota trucks and SUVs equipped with the rugged 8-inch live axle. Compatible with both front and rear axles, this air-actuated locker is designed for 30 spline axle shafts measuring 1.31 inches in diameter and fits 50mm bearing setups.
With the flick of a switch, the ARB Air Locker locks the axle shafts solidly together, ensuring both wheels turn simultaneously for unmatched grip in challenging off-road conditions such as mud, rocks, or snow. When unlocked, the differential functions as a standard open unit, preserving smooth and safe on-road drivability.
The pneumatic locking system enables activation at any speed without driveline damage, giving you control and confidence over your terrain. Its two-piece steel construction offers durability and reliability, backed by a 5-year warranty.
