Old Man Emu BP-51 Driver-Side Front Remote-Reservoir Coilover for 5th-Gen 4Runner (2010–2024)

The BP-51 front coilover delivers precise suspension control across the full range of wheel travel. Patented design improves low- and high-speed damping while maintaining comfort at ride height. Increased bore and oil volume enhance force generation, making it ideal for off-road and on-road performance.

Constructed entirely in-house by Old Man Emu, the coilover features X5K steel springs and high-strength components. Twin-tube and bypass engineering ensure consistent damping while reducing wear under heavy loads.

This system uses position-sensitive, internal bypass damping to tailor force based on suspension compression. Damping progressively increases toward end-travel zones, offering maximum control and stability.

Optimized for coilover-equipped 5th-Gen 4Runners, the BP-51 front coilover provides ride comfort, enhanced steering response, and controlled handling. On-car adjustability allows fine-tuning for specific terrain, load, and driving style.

High-quality materials and precision engineering ensure the BP-51 coilover withstands repeated off-road impacts and road hazards. Oil volume, bore size, and construction design combine to maintain long-term performance and reliability.
