Why Choose ARB Air Locker?

• On-Demand Traction: Engage the locker via a switch to lock both wheels together.
• Gear Ratio Specific: Optimized for 3.73 and down gear sets for a perfect fit.
• Reliable Engineering: High-strength materials ensure longevity under stress.
• Street-Friendly: Operates as an open differential when disengaged for smooth cornering.

The ARB Air Locker works by using air pressure to lock the internal gears, ensuring that power is distributed equally to both wheels. This eliminates the common issue of one wheel spinning freely in mud or over obstacles. When you reach the pavement, simply disengage the system to return to open differential operation, preserving your tires and improving handling. This unit is a must-have for any serious off-road enthusiast working on classic GM platforms. Trust in the proven design of the ARB Air Locker to provide the reliability and performance you demand.
