ARB Old Man Emu BP-51 Rear Bypass Shock Absorber for Toyota 4Runner/FJ Cruiser 2010-2023 - Single (BP5160025)

Fits select 2010-2023 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser. This Old Man Emu BP-51 (Bypass 51mm diameter bore) shock absorber brings internal bypass technology to daily-driven adventure vehicles, providing position-sensitive damping that is fully adjustable on the vehicle.

The BP-51 series is engineered to solve the trade-off between daily ride comfort and off-road control. By utilizing internal bypass passages, the shock offers a plush ride during normal travel while increasing damping force at the ends of the stroke (end-zone damping) to prevent bottoming out during aggressive off-road use. Both rebound and compression are independently adjustable, allowing you to tune the suspension for varying loads or terrain without removing the shock from the vehicle.

Construction features high-grade 6061 T6 aluminum for the body and reservoir, providing superior heat dissipation compared to traditional steel shocks. The components are finished with a Type 3, 40-micron hard-anodized coating to ensure maximum corrosion resistance and durability against stone peppering in harsh environments.
