The Old Man Emu BP-51 Shock Absorber, part number ARBBP5160078, is engineered for 2025-2026 Toyota 4Runner models seeking improved ride comfort, handling, and off-road control. Developed and tested by ARB’s Old Man Emu ride engineers in Australia, this position-sensitive bypass shock absorber combines comfortable on-road performance with increased end-zone damping for demanding trails and uneven terrain. Its bolt-on design installs without vehicle modifications, making it a practical upgrade for drivers who require versatile suspension performance.
The BP-51 uses an internal bypass system with a remote reservoir to increase oil capacity and help manage operating temperatures during extended use. Its 2-inch internal bore supports consistent damping performance, while independently adjustable compression and rebound settings allow the shock to be tuned across a broad range for different terrain, vehicle setups, and driving preferences. This adjustability helps provide greater chassis control without sacrificing everyday drivability.
