ARB Air Locker Differential Gear Set Side Pin

ARB Air Locker differential gear sets and side (cross shaft retaining) pins are replacement internal components for ARB Air Locker selectable locking differentials. They help restore the strength and reliability of your locker's internal gear train after wear, service or rebuild work.

Key Features:

• Forged gear design: ARB uses forged gears, the type found in heavy-duty commercial, race and agricultural transmissions, to handle the forces on the side and pinion gears.
• Patented timed locking system: The locking mechanism supports the side gear teeth, which adds torque-handling capability when you lock the differential.
• Hardened cross shaft retaining pin: ARB makes the pin as a one-piece hardened part. It locks into the assembly with a tapered thread junction to hold the cross shafts securely.
• Alloy steel construction: The gears use forged nickel alloy steel with surface treatments, and the spider block is billet-machined alloy steel.
• Four-pinion layout: ARB Air Lockers use four pinion gears, twice as many as some lighter-duty open differentials.

An ARB Air Locker lets your differential run open for normal driving and lock on demand for full traction off-road. Genuine ARB service parts keep the locker working as designed. Check the correct part number for your specific Air Locker model before you order.
