BP-51 Suspension Kit with 3 in Front Lift, 0 in Rear Lift, 0–330 lb Front Load Rating, and 0 lb Rear Load Rating for 6th-Gen 4Runner (2025–Present)

The Old Man Emu BP-51 Suspension Kit is engineered for 6th-Gen 4Runner owners who want a capable, tunable suspension system with a defined front lift and no rear lift. Developed as a matched package, it combines advanced damping technology, adjustable suspension response, and durable construction to help the vehicle remain composed across everyday driving and off-road trails.

At the core of the system is BP-51's position-sensitive design. Damping characteristics respond to the shock's position throughout suspension travel, managing movement rather than applying the same response at every point.

BP-51 technology provides comfortable road manners while maintaining control and handling when the suspension works harder off pavement. Its adjustable damping gives owners additional flexibility to tailor that damping balance.

Repeated movement generates heat during extended off-road driving. The BP-51 design adds oil capacity to support cooling and performance, helping the dampers manage the thermal demands associated with continued operation.

These BP-51 shocks provide 10 levels each of compression and rebound adjustment. These on-vehicle adjustments let drivers refine the suspension to suit build needs, vehicle equipment, and on-road and off-road driving conditions.
