The ARB Air Locker for the Nissan H233B rear axle solves that with a driver-selectable, air-operated lock: flip the switch and both wheels drive together for 100% traction, switch it off and you keep quiet, predictable open-diff manners on the highway.\u003c\/p\u003e\u003cp\u003eThis carrier is built for the 31-spline H233B differential used across Nissan's D21 Hardbody, Frontier, Xterra and Pathfinder platforms. Because engagement is on demand, you get a fully locked axle exactly when the terrain calls for it — no permanent handling or tire-wear penalty the rest of the time.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSelectable, air-operated 100% differential lock\u003c\/li\u003e\n\u003cli\u003eForged internals sized for the H233B 31-spline axle\u003c\/li\u003e\n\u003cli\u003eEngages instantly from an ARB air source (compressor or tank)\u003c\/li\u003e\n\u003cli\u003eBolt-in replacement for the factory carrier\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eTrade-off: an Air Locker needs a compressed-air supply, so budget for an ARB compressor if you don't already run one, and have the carrier professionally installed and set up to your ring-and-pinion.\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eSelectable air-operated locking differential\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifferential \/ axle\u003c\/td\u003e\n\u003ctd\u003eNissan H233B (rear)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpline count\u003c\/td\u003e\n\u003ctd\u003e31\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eActuation\u003c\/td\u003e\n\u003ctd\u003eCompressed air — ARB air source required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating pressure\u003c\/td\u003e\n\u003ctd\u003e100 psi (nominal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number (MPN)\u003c\/td\u003e\n\u003ctd\u003eRD136\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGTIN\u003c\/td\u003e\n\u003ctd\u003e881348007308\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eARB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eFit is determined by your differential type and spline count, not model year — confirm your H233B axle before ordering.
