ARB Old Man Emu BP-51 Bypass Suspension Kit for 2010-2023 Toyota 4Runner (2.5in Front / 0in Rear Lift)

Fits 2010-2023 Toyota 4Runner (SR5, Trail, TRD Off-Road, TRD Pro, Limited, and Venture) models.

The ARB Old Man Emu BP-51 High-Performance Bypass Suspension Kit brings race-inspired internal bypass technology to the Toyota 4Runner. Unlike traditional shocks that rely solely on fluid speed, the BP-51 series offers position-sensitive damping. This allows for a compliant, comfortable ride during normal suspension travel while providing significantly increased damping force as the shock approaches full compression or extension to prevent bottoming out.

Engineered for the 5th Gen 4Runner platform, this kit provides a 2.5-inch front lift to accommodate larger tires and improve approach angles, while maintaining the factory rear height. The system is specifically tuned for vehicles with 0 to 330 lbs of additional front-end weight, making it ideal for stock vehicles or those equipped with lightweight hidden winch mounts or aluminum bumpers. The 6061 T6 aluminum shock bodies offer superior heat dissipation compared to steel, ensuring consistent performance during long stints on corrugated tracks.
