The ARB Air Locker RD235 brings selectable locking to the legendary GM 14-bolt 10.5" full-float axle (35-spline). Popular under 3/4- and 1-ton GM trucks and swapped into countless heavy off-road builds, the 14-bolt is famous for strength — and this Air Locker lets you lock it 100% on demand and unlock instantly for open-diff road manners.
ARB's forged four-pinion centre suits the high torque loads of heavy trucks, large tyres and low gearing. Air-operated engagement is instant and repeatable, giving you full control of traction in any gear without the constant-lock compromises of an automatic locker.
