Air Locker Differential – GM 14 Bolt 10.5″ Full Floating (RD235) 35-spline – ARB

The ARB Air Locker GM 14 Bolt 10.5″ Full Floating Differential (model RD234) is a high-end solution to drastically improve the traction of your 4x4 or utility vehicle equipped with a GM 14 Bolt 10.5″ full floating axle. Designed by ARB, the world leader in locking differentials, this system offers instant and on-demand lockable traction, directly from the cabin.

🔥 Key Features

100% On-Demand Traction: fully locks both wheels to maximize grip in difficult conditions.

Easy pneumatic activation from inside the vehicle, without leaving your seat.

Ultra-robust two-piece design, with few moving parts for maximum reliability

Functions as an open differential when not locked, for normal road handling.

🚗 COMPATIBILITY

This differential is intended for:

Axle GM 14 Bolt 10.5″ Full Floating

Spline count: 35 teeth (requires installation of matching axle shafts)

For gear ratio: 4.10 and lower (For 4.56 and higher ratios, a "thick" ring and pinion set is required).

💡 HOW IT WORKS

The ARB Air Locker is a pneumatically locking differential. Once activated, it prevents the internal gears from rotating independently, thus linking both axle shafts for maximum traction. When deactivated, it behaves like a standard differential. Activation can be done at any speed, making it a very practical solution for technical off-roading.

🛠️ INSTALLATION AND AIR COMPRESSION

This system requires a 12V air compressor (sold separately) to actuate the lock. The included components allow you to connect the air to the differential with the switch and valve.
