Description
Dominate off-road terrain with the ARB RD181 Air Locker, purpose-built for Nissan R180A front axles with 27 spline shafts and a 10-bolt ring gear. This high-performance differential locker delivers 100% traction on demand, giving you the power to overcome rocks, ruts, mud, and snow at the flip of a switch.
Engineered with a pneumatically operated locking mechanism, the RD181 eliminates wheel spin by locking both front wheels together, ensuring they turn at the same rate for superior grip. When disengaged, it functions like a standard open differential, preserving factory drivability on pavement.
The RD181’s rugged two-piece steel design ensures maximum durability with minimal moving parts, reducing wear and increasing reliability in extreme off-road conditions. The steel-reinforced annular seal is built to withstand harsh climates, and the patented timed locking mechanism ensures instant engagement and fast release.
This locker is ideal for drivers looking to upgrade their R180A-equipped Nissan vehicles. An ARB air compressor is required for operation (sold separately).
