Available for both front and rear axles, the locker allows the differential to operate normally during everyday driving and mechanically locks the axle when additional traction is needed.\n\u003c\/p\u003e\n\n\u003cp\u003e\nDesigned to fit all Grenadier model variants, including vehicles equipped with OE locking or non-locking differentials, the Air Locker adds proven off-road capability without compromising normal on-road drivability.\n\u003c\/p\u003e\n\n\u003ch3\u003eLong Product Intro\u003c\/h3\u003e\n\n\u003cp\u003e\nThe ARB Air Locker is a proven selectable locking differential designed to give the driver complete control over when additional traction is needed.\n\u003c\/p\u003e\n\n\u003cp\u003e\nAt the push of a switch, compressed air engages the locking mechanism and mechanically locks the differential, allowing both wheels on the axle to work together. This reduces the need to rely on speed or momentum when crossing rocks, mud, sand, ruts, steep inclines, and other low-traction terrain.\n\u003c\/p\u003e\n\n\u003cp\u003e\nBy allowing difficult obstacles to be approached at slower, more controlled speeds, an Air Locker can help improve passenger comfort and control while reducing unnecessary drivetrain wear, vehicle damage, and trail impact. ARB also notes that Air Lockers can provide additional control when maneuvering heavy loads such as trailers, caravans, or boats on inclines and declines.\n\u003c\/p\u003e\n\n\u003cp\u003e\nARB Air Lockers have been tested and used in more than 100 countries and feature a simple, durable design with minimal moving parts for long-term reliability.\n\u003c\/p\u003e\n\n\u003cp\u003e\nARB currently lists October 2026 as the expected availability date for the INEOS Grenadier Air Locker.\n\u003c\/p\u003e\n\n\u003ch3\u003eBenefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProvides 100% traction on demand when additional grip is needed\u003c\/li\u003e\n  \u003cli\u003eMaintains normal differential operation and on-road drivability when disengaged\u003c\/li\u003e\n  \u003cli\u003eAllows difficult terrain to be approached with less reliance on speed and momentum\u003c\/li\u003e\n  \u003cli\u003eHelps improve control when climbing, descending, or maneuvering heavy loads\u003c\/li\u003e\n  \u003cli\u003eAvailable for front, rear, or dual-locker Grenadier setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% Selectable Locking:\u003c\/strong\u003e Mechanically locks the differential when engaged while remaining open during normal driving\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFront \u0026amp; Rear Compatibility:\u003c\/strong\u003e RD278 fits both front and rear Grenadier differentials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAll-Model Fitment:\u003c\/strong\u003e Compatible with OE locked and non-locked INEOS Grenadier variants\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFast, Proven Engagement:\u003c\/strong\u003e Patented timed locking mechanism provides rapid locking and unlocking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFactory-Style Switch Integration:\u003c\/strong\u003e Can be configured to operate through the Grenadier’s existing roof-console auxiliary switches\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e100% Traction When You Need It\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eLock it when conditions demand it\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e\nThe Air Locker remains disengaged during normal driving and can be activated when additional traction is required, providing full locking capability without permanently changing everyday differential behavior.\n\u003c\/p\u003e\n\n\u003ch3\u003eMore Control.
