Old Man Emu BP-51 Suspension Kit with 2.5 in Front Lift, 2 in Rear Lift, 0-330 lb Front Load Rating, and 880 lb Rear Load Rating for 5th-Gen 4Runner with Kinetic Dynamic Suspension System (2010–2024)

The Old Man Emu BP-51 Suspension Kit is engineered to deliver precise suspension control and ride quality for 5th-Gen 4Runners with KDSS under heavy rear loads. Internal bypass shock technology provides position-sensitive damping, while adjustable spring seats and remote reservoirs allow for tailored performance. The kit enhances front and rear ride height, stability, and articulation, ensuring balanced performance and comfort whether on-road or tackling challenging off-road trails.

BP-51 shocks feature 6061-grade aluminum bodies with Type III hard anodized finish for heat dissipation, corrosion resistance, and durability. Remote oil reservoirs expand fluid capacity, improving cooling and performance during extended off-road use.

Built for extreme off-road and on-road use, the BP-51 system resists deformation, corrosion, and wear. Heavy-duty construction and protective finishes maintain long-term reliability under high load and challenging terrain conditions.

Independent compression and rebound tuning at ten levels, combined with remote oil reservoirs and adjustable spring seats, allows drivers to customize suspension performance for front and rear load, terrain, and personal driving preferences.

The BP-51 Suspension Kit is a direct replacement for stock or compatible aftermarket systems. All hardware and remote reservoirs are included to ensure proper alignment, KDSS integration, and secure installation using standard tools.
