ARB RD127 Air Locker Differential for Land Rover 10 Spline 3.54 Ratio

The ARB RD127 Air Locker is a pneumatically-activated locking differential designed specifically for Land Rover vehicles with banjo-style differentials, 10 spline axles, and 3.54 gear ratios. This advanced traction control system provides 100% power to both wheels on demand, ensuring maximum traction in challenging off-road conditions including mud, sand, snow, and rock crawling.

Key Features:

• On-demand locking differential activated by compressed air for instant traction control
• Designed for Land Rover banjo-style differentials with 10 spline configuration
• Engineered for 3.54 axle ratio applications
• Maintains normal open differential operation on-road for optimal handling and tire wear
• Forged steel construction for maximum strength and durability
• Complete kit includes replacement differential center, dash-mounted activation switch, solenoid valve, air line, and bulkhead fittings

Unlike limited-slip differentials that require wheel spin to engage, the ARB Air Locker provides instant, complete lockup before traction is lost. When unlocked, the differential operates as a standard open differential for normal driving conditions. When locked, both wheels rotate at the same speed regardless of traction conditions, dramatically improving vehicle capability in extreme terrain. Professional installation recommended.
