ARB Old Man Emu BP-51 Bypass Suspension Kit for 2010-2023 Toyota 4Runner (FR 2.5in/0-330lb - RR 0in/0lb)

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

The Old Man Emu BP-51 (Bypass 51mm) suspension kit brings professional-grade internal bypass technology to the Toyota 4Runner platform. Unlike traditional velocity-sensitive shocks, the BP-51 system is position-sensitive, utilizing internal passage-ways to redirect oil flow around the piston at specific points in the stroke. This results in a plush, compliant ride during normal driving and significantly increased damping force at the extremes of travel to prevent bottoming out during aggressive off-road use.
