ARB RD111 Air Locker - 30 Spline - 3.91 & Up - Toyota 8" IFS (53mm Bearing) - Select Toyota 2003-2024

Fits select 2003-2024 Toyota 4Runner, Tacoma, FJ Cruiser, Land Cruiser, and Tundra models with the Toyota 8-inch IFS front differential.

The ARB RD111 Air Locker provides 100% traction on demand while maintaining the drivability of a conventional open differential on the street. This pneumatically operated locking differential allows you to tackle technical terrain by ensuring both wheels receive equal power, preventing axle shafts from turning independently. The patented "timed" locking mechanism offers high-strength engagement and ultra-fast unlocking for immediate response on the trail.

Constructed with a two-piece design, this locker is engineered for maximum reliability with minimal moving parts. It features a steel-reinforced, elastomer-bonded annular seal designed to withstand extreme temperature fluctuations. The RD111 is designed for Toyota 8-inch IFS applications with a 53mm bearing and 30-spline axle shafts, specifically for gear ratios of 3.91 and numerically higher.
