Product Description

The ARB 081801SP Air Locker Seal Housing Kit with O-Rings is a genuine ARB differential service part designed for use in Air Locker installations on Dana 30 and Dana 35 axles. This kit provides the precision-fit seal housing and high-quality O-rings that help maintain a reliable seal between the Air Locker's internal components and the differential case, ensuring proper air pressure retention for consistent locker engagement.

Over time and with heavy use, differential components such as Air Lockers may experience wear on seals and O-rings, especially if subjected to harsh off-road conditions. Replacing these seal components with ARB's 081801SP kit helps prevent air and fluid leaks that could compromise differential performance. This kit is also critical for anyone performing a locker rebuild or routine Air Locker service, making maintenance more reliable and helping extend the service life of the locker.

Installation of the seal housing kit typically occurs during a differential disassembly and rebuild, as it replaces worn seals and restores a tight, leak-free interface. This part is suitable for a wide range of ARB locker models that share the same housing design, giving off-road and 4x4 enthusiasts a trusted service solution for maintaining peak differential performance.
