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 (2010–2024)

The Old Man Emu BP-51 Suspension Kit is a performance-tuned system that maintains handling, comfort, and stability for 4Runners carrying moderate rear weight. Adjustable internal bypass shocks allow drivers to dial in compression and rebound independently, while remote reservoirs extend oil capacity for sustained off-road performance. This kit combines lift, load handling, and ride control in a reliable, engineered package for both trail and street applications.

BP-51 shocks feature anodized 6061-grade aluminum bodies for heat dissipation and corrosion resistance, paired with heavy-duty steel mounting hardware. Reservoirs expand fluid capacity to maintain consistent damping under extended suspension travel.

The internal bypass design delivers position-sensitive damping that adapts to changes in terrain and load. Ten compression and rebound levels allow precise suspension tuning, improving handling, traction, and ride quality on and off the trail.

Shock bodies, mounts, and reservoirs are engineered to resist wear, corrosion, and deformation in harsh environments. The kit maintains performance and structural integrity during prolonged off-road use and heavy-load operation.

This BP-51 Suspension Kit installs as a direct replacement for factory or compatible aftermarket suspension systems. All included hardware ensures proper alignment and secure mounting without modifications.
