BP-51 Rear Remote-Reservoir Shock for 0 in Lift and 0 lb Load for 6th-Gen 4Runner (2025–Present)

The Old Man Emu BP-51 Rear Remote-Reservoir Shock is designed to give the 6th-Gen 4Runner's rear suspension a tunable damping solution without changing the specified ride height. Its combination of internal-bypass technology, remote-reservoir construction, and independent adjustments supports a tailored suspension response for varied driving conditions.

BP-51 technology varies damping based on the shock's position, managing movement through different stages of compression and extension, supporting a composed ride on roads and controlled response over uneven terrain.

The shock offers 10 levels of compression and rebound adjustment. Drivers can refine how the suspension responds as it compresses and returns, tuning the ride to their preferences and the conditions the vehicle regularly encounters.

Rear shocks influence body movement over changing surfaces. BP-51 shocks balance comfort and chassis control, providing adjustability for owners who want to refine rear suspension behavior for both daily use and off-road travel.

Alongside increased oil capacity, the remote reservoir supports the system's approach to heat management during repeated suspension movement, helping maintain damping performance across extended drives and trail sessions.
