Description
The ARB RD151 Air Locker transforms the off-road capabilities of your Toyota Tundra or Land Cruiser by offering full control over front axle traction. Designed for the 8-inch IFS (Independent Front Suspension) front differential, this air-actuated locker features 34 spline axle compatibility and a robust two-piece steel design.
When engaged, the RD151 forces both front wheels to rotate at the same speed, maximizing forward motion in mud, snow, rocks, or sand. Disengage it for smooth and safe handling on pavement—just like a stock open differential. The internal pneumatically controlled locking mechanism ensures near-instant activation with the flip of a switch.
Perfect for overlanding, rock crawling, or working in tough terrain, this locker delivers the traction you need while minimizing vehicle wear and environmental damage.
Note: ARB air compressor required for operation (sold separately).
