The ARB GM 14 Bolt air locker RD234 for your 40 spline axle for 4.10 & down gear ratios or RD235 for your 35 spline axle for 4.10 & down gear ratios, can instantly lock differentials and allow you to tackle the toughest off-road terrain. The world's best traction aid, ARB Air Lockers keep you moving in all conditions.

Air Lockers from ARB are currently available in over 100 configurations to suit a wide range of off-road and 4x4 vehicles from around the world. Because the GM 14 Bolt ARB® #RD234 and #RD235 air lockers are only engaged when needed, they can be installed in BOTH the front and rear axles, with separate switches independently controlling the air locker from within the off-road truck or vehicle.
