ARBRD234
The ARB Selectable Air Locker for the GM 14-Bolt 10.5" Full-Float Axle is a selectable locking differential that delivers maximum traction on demand. With the flip of a switch, compressed air activates the locking mechanism, mechanically coupling both axle shafts together so each wheel receives equal torque regardless of available traction. When unlocked, it functions as a conventional open differential for predictable street manners and easier steering.
Designed for heavy-duty off-road applications including rock crawling, Ultra4 racing, trail rigs, and overland builds, the ARB Air Locker combines forged steel construction with ARB's proven pneumatic locking technology for exceptional strength and reliability. Unlike automatic lockers, it only engages when needed, giving you complete control over traction while reducing drivetrain stress during normal driving.

Important Fitment Notes:
A selectable air locker gives you the best of both worlds by allowing the differential to operate normally during everyday driving while instantly providing a fully locked axle when maximum traction is required. Locking both axle shafts together eliminates differential action, ensuring torque is delivered equally to both wheels regardless of available traction.
ARB's patented air-actuated locking mechanism is engineered for exceptional durability using a forged steel locking gear, precision-machined components, and a reinforced annular air seal designed to withstand extreme temperatures and repeated engagement cycles. This makes the Air Locker an excellent choice for rock crawlers, Ultra4 race vehicles, overland rigs, and heavy-duty trail builds where predictable traction and driver control are critical.
