Built for the ARB RD90 Air Locker Differential for Toyota 7.5-inch IFS Axles, this ARB component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.
The ARB RD90 Air Locker Differential is a high-performance traction solution designed to enhance off-road capability for Toyota trucks and SUVs. Built with durable steel construction, this differential provides reliable, instant lock functionality at the flick of a switch, allowing drivers to tackle challenging terrains with confidence. Its pneumatically operated locking system prevents internal gears from rotating independently, ensuring both wheels turn together for maximum traction. When disengaged, it operates as a conventional open differential, maintaining smooth on-road driving and reducing driveline wear. This feature makes the ARB RD90 ideal for both off-road adventures and everyday driving, as it enhances vehicle control and safety without compromising drivability.

- Instant lock activation: Provides 100% traction on demand with a simple switch.
