ARB Rear Adjustable Shock for Toyota Land Cruiser 300 Series Provides Direct Bolt-In Replacement With Real-Time Damping Control for Towing and Trail Running

• Monotube damper core utilizes a thick-walled chrome-moly piston rod and a fixed high-pressure nitrogen charge to maintain consistent resistance under heavy braking or sudden drops without hydraulic sponging.
• External multi-click adjustment dial lets you tune compression response in the field, shifting between firm setups for loaded cargo and softer settings for unloaded daily commuting.
• OEM bracket alignment mounts directly to existing Land Cruiser 300 Series chassis points, requiring no cutting, drilling, or secondary alignment procedures after installation.
• High-flow valve stack and enlarged body diameter accelerate piston movement to vent heat quickly, preventing performance loss during repeated wheel bumps or steep fire-road descents.
• Triple-lip sealing system with rubber dust shield blocks fine silica dust, water spray, and trail salt from entering the damping circuit, preserving internal tolerances and extending service intervals.
• Vehicle-tuned valving matches the 300 Series rear axle mass, correcting excessive rear squat under payload while keeping tire contact patches planted for predictable steering response.

Each shock expands to 35 inches in overall length with a 7 × 4 inch packed cross section and weighs 13 pounds per unit. The sealed chamber ships with pre-set gas pressure charges that install without line bleeding or fluid topping. Built exclusively for the upgraded frame rails and revised rear suspension geometry of the Land Cruiser 300 Series, these dampers slot into factory positions to restore track-ready stability without altering mounting hardware or introducing unwanted body roll.
