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

The Old Man Emu BP-51 Suspension Kit is designed for 6th-Gen 4Runner owners seeking increased front ride height while retaining the specified factory-height rear configuration. The package pairs BP-51 damping technology with tubular front upper control arms to create a coordinated upgrade that accounts for both suspension performance and front-end geometry.

BP-51 shocks use an internal-bypass design that provides position-sensitive damping. This helps respond to changing terrain and movement, supporting a balance of comfort and control across everyday roads and off-road routes.

The system offers 10 levels of independent compression and rebound adjustment, with tuning performed directly on the vehicle. Separate controls allow drivers to refine how the suspension responds to compression and extension.

The tubular front upper control arms correct front suspension geometry affected by the lift. They complement the raised front suspension by addressing changes in component positioning that can occur when ride height is increased.

The BP-51 shock bodies are constructed from 6061-T6 aluminum, providing strength, heat dissipation, and corrosion resistance, important considerations for dampers exposed to repeated use and changing environmental conditions.
