ARB RD232 Air Locker Differential - 32 Spline for 16-23 Toyota Tacoma
Instant Traction on Demand: The patented Air Locker design allows you to switch from an open differential to a 100% fully locked state instantly via a dash-mounted switch, providing relentless drive to both wheels regardless of surface traction.
Forged Internal Gearing: Built with high-strength forged gears that offer superior tooth support and durability compared to standard cut gears, ensuring the differential can handle high-torque off-road maneuvers without failure.
Patented Two-Piece Design: The structural integrity of the locker is enhanced by a two-piece case machined from a single block of nodular iron, offering maximum support for the ring and pinion gear set under extreme loads.
Reliable Pneumatic Operation: Utilizes a heavy-duty internal seal and a high-temperature resistant Viton O-ring system to ensure leak-free performance and consistent engagement even in the harshest environments.
Superior Spline Strength: Available in both 30-spline (RD132) and heavy-duty 32-spline (RD232) configurations, allowing you to match your locker perfectly to your Tacoma’s axle shafts for a precision, high-strength fit.
The ARB Air Locker Differential is the industry-leading solution for 2016-2023 Toyota Tacoma owners who demand uncompromising off-road performance. While factory limited-slip or open differentials often leave you stranded when one wheel loses contact with the ground, the Air Locker ensures that 100% of available torque is distributed equally to both wheels. This pneumatic locking system allows you to maintain a "street-friendly" open differential for daily driving, then transform your Tacoma into a technical climbing machine at the push of a button. Whether you are navigating deep mud, loose shale, or vertical rock steps, these lockers provide the predictable traction needed to keep moving forward.
Engineered for maximum reliability, these units are available in two specific variations for the 3rd Gen Tacoma. The ARB RD132 is designed for standard 30-spline axle applications, while the ARB RD232 caters to reinforced 32-spline setups. Both models feature ARB’s legendary two-piece case design and forged gears, providing a significant strength upgrade over the factory differential carrier. Requiring an onboard air compressor for operation, these lockers are built to withstand the most punishing conditions on the planet and are backed by a comprehensive five-year warranty for total peace of mind on the trail.
