BP-51 Front Passenger-Side Remote-Reservoir Coilover with 3 in Lift and 0–330 lb Load Rating for 6th-Gen 4Runner (2025–Present)

The Old Man Emu BP-51 Front Passenger-Side Remote-Reservoir Coilover is engineered to improve suspension response across a broad range of driving conditions. Designed for the 6th-Gen 4Runner, it combines a big-bore coilover platform with position- and velocity-sensitive damping to help balance everyday ride comfort with the chassis control required for off-road travel.

BP-51 damping technology responds to both suspension position and velocity, allowing it to manage changing suspension demands throughout its travel, helping provide a more controlled response as surfaces and conditions vary.

Substantial end-zone damping helps manage suspension movement near the limits of travel. The system delivers comfort around town without overlooking the need for damping when the vehicle encounters larger movement inputs.

Consistent suspension control helps the vehicle respond to changing surfaces. The BP-51 coilover is extensively tested under demanding conditions and engineered for confident handling and chassis control during off-road use.

The remote-reservoir configuration supports the BP-51 for demanding use. Combined with the big-bore damper architecture, it forms part of a system engineered to manage heat and control damping across a variety of conditions.
