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

The BP-51 passenger-side front coilover provides consistent, position-sensitive damping to manage wheel travel precisely. The system increases damping near end zones while maintaining comfort at ride height, delivering confident handling on-road or off-road.

Built in-house by Old Man Emu, this coilover features robust X5K steel springs and high-strength twin-tube construction. The design ensures durable, repeatable performance even under heavy load or rough terrain.

Internal bypass technology progressively adjusts damping based on suspension compression, increasing control through extreme compression zones. Position-sensitive design enhances traction, stability, and comfort across all terrains.

Optimized for 5th-Gen 4Runners with coilover setups, this front passenger-side BP-51 offers responsive handling, improved ride quality, and precise suspension control. On-car adjustability enables customization to match terrain, load, and driving style.

Engineered for longevity, the Old Man Emu BP-51 uses premium materials and an oversized bore design to withstand repeated off-road impacts and maintain high-performance damping over time.
