4Runner 2010-2024 Toyota 4WD Rear BP-51 Shock by Old Man Emu

Old Man Emu brings cutting-edge racing technology to everyday adventures with the BP5160025 BP-51 (Bypass 51mm bore) shock absorbers for the Toyota 4Runner. These revolutionary, patent-pending shocks are engineered to deliver unmatched performance on and off the road. Extensively tested in Australia’s harshest conditions, these position-sensitive bypass shock absorbers with remote reservoirs are designed to bolt directly onto your vehicle without any modifications.

The BP-51 shocks, with external on-vehicle adjustable damping for rebound and compression, allow you to fine-tune your ride to suit various terrains and setups. Around town, you can enjoy exceptional ride comfort, and off-road, you can experience superior chassis control and handling. Built from 6061 T6 aluminum with Type 3 40-micron hard anodizing, these shocks offer excellent heat dissipation, corrosion resistance, and protection against stone damage.

Bypass technology in BP-51 coilovers provides an additional fluid flow path around the piston, allowing the shock to adapt to different driving conditions. This design offers a smoother, more comfortable ride during normal driving, while increasing control on rough terrain by generating more damping at the ends of the stroke to absorb larger impacts and prevent harsh bottoming out.
