This engagement ring is a critical internal component located inside the ARB Air Locker differential assembly. It is the part that physically slides across to engage with the side gear, effectively 'locking' the differential and forcing both axles to turn at the same speed.
You may need to replace this part if your ARB Air Locker is failing to engage, disengage, or is making grinding noises during operation. This is often due to wear and tear from extensive use, damage from engaging the locker while a wheel is spinning, or internal contamination causing premature wear on the moving parts. Kit also includes the wave style spring washer.
If a worn or damaged engagement ring is not replaced, your differential lock will become unreliable or completely inoperable. This leaves you without the crucial traction advantage needed in difficult off-road terrain, potentially getting you stranded. In a worst-case scenario, a broken ring could disintegrate, sending metal fragments throughout the differential and causing catastrophic damage to expensive gears and bearings.
