Old Man Emu BP-51 Driver-Side Rear Remote-Reservoir Shock for Toyota Tacoma (2005–2023)

Designed, tested, and manufactured entirely by Old Man Emu ride engineers, the BP-51 shock absorber applies racing-derived bypass technology to improve chassis control, heat management, and tunability. Precision-machined components and a remote reservoir work together to deliver consistent damping performance across extended off-road use and daily driving conditions.

Machined from 6061-T6 aluminum, the shock body and remote reservoir are engineered for strength, reduced weight, and effective heat dissipation. Type III hard anodizing improves resistance to corrosion and stone damage, ensuring long-term durability in harsh environments.

An internal bypass system with shim-controlled, position-sensitive valving provides compliant damping at ride height while progressively increasing resistance near full compression and rebound. This design enhances stability, control, and impact management during aggressive off-road driving.

Large-bore architecture and increased oil volume improve damping consistency and responsiveness. End-zone control is significantly enhanced, resulting in improved handling, reduced body movement, and greater confidence across uneven terrain.

Independent compression and rebound adjusters allow precise tuning to match vehicle setup, load, and terrain. Adjustments are made directly on the vehicle, enabling quick refinement without shock removal.
