Old Man Emu BP-51 Suspension Kit with 2.5 in Front Lift, 2 in Rear Lift, 0-330 lb Front Load Rating, and 440 lb Rear Load Rating for 5th-Gen 4Runner with Kinetic Dynamic Suspension System (2010–2024)

The Old Man Emu BP-51 Suspension Kit is designed for drivers seeking balanced front and rear lift with precise damping control. Internal bypass shocks provide position-sensitive performance for both compression and rebound, while adjustable spring seats and remote reservoirs allow tuning for vehicle weight, terrain, and driving preference. The kit enhances articulation, stability, and ride quality for both off-road adventures and daily driving.

Each BP-51 shock features a 6061-grade aluminum body with a Type III hard anodized finish for improved heat dissipation, corrosion resistance, and durability. Remote-mounted oil reservoirs increase fluid capacity, optimizing cooling during extended off-road use.

Constructed to withstand demanding on-road and off-road use, the BP-51 system resists wear, corrosion, and deformation. Protective finishes and robust materials maintain long-term reliability even under challenging payload and terrain conditions.

Independent compression and rebound tuning, along with adjustable spring seats and remote reservoirs, enables fine-tuning of suspension performance for both front and rear, allowing drivers to optimize ride height, handling, and damping characteristics for specific loads and terrain.

The BP-51 Suspension Kit is a direct replacement for OE or compatible aftermarket suspension components. All included hardware and remote reservoirs allow secure installation and proper alignment, ensuring full integration with KDSS functionality.
