ARB RD103 Air Locker Locking Differential

The ARB RD103 Air Locker is a selectable locking differential designed to provide maximum traction in challenging off-road conditions. Unlike limited-slip differentials that partially transfer power, the ARB Air Locker mechanically locks both axle shafts together on demand, ensuring equal power distribution to both wheels regardless of traction conditions.

Key Features:

• 100% lockable differential activated by compressed air for on-demand traction control
• Seamless engagement and disengagement via dash-mounted switch
• Complete kit includes replacement differential carrier, air compressor activation switch, solenoid valve, air line, and bulkhead fittings
• Proven durability in extreme conditions from rock crawling to desert racing
• Functions as an open differential during normal driving for smooth handling and tire wear
• Pneumatic activation provides reliable operation without electrical components in the differential housing

The ARB Air Locker represents decades of engineering refinement as the world's most widely used aftermarket locking differential. When traction is lost on one wheel, simply activate the locker to mechanically couple both wheels and maintain forward momentum through mud, sand, snow, or over obstacles. When the trail smooths out, disengage the locker for normal driving characteristics.
