Old Man Emu BP5190036R BP-51 Front Right Coilover Strut for 2025–2026 Toyota 4Runner

Old Man Emu brings racing technology to every day adventures: BP-51 (Bypass 51mm diameter bore) shock absorbers feature revolutionary, patent pending technology developed to deliver unparalleled on and off road performance. Developed and extensively tested under the harshest conditions in Australia, these big bore, position sensitive bypass shock absorbers with remote reservoir are designed to bolt onto your vehicle without any vehicle modifications and combine considerable ride comfort around town with significant amounts of end-zone damping for exceptional chassis control and handling off road. The damping performance is easily adjustable across an wide range of rebound and compression, resulting in significant changes to the ride performance of your vehicle, enabling an custom tune to suit the conditions and vehicle set up. The body, reservoir and components are all made from 6061 T6 aluminum, Type 3 40 micron hard anodized ensuring exceptional heat dissipation, corrosion resistance and resistance to stone damage. Not only designed, developed and tested entirely by ARB's team of Old Man Emu ride engineers, all BP-51 shock absorbers are manufactured in-house by ARB. In order to achieve this, significant investment has been made in state of the art machinery providing ARB total control of the manufacturing process to ensure the highest possible quality.

Upgrade the front suspension of your 2025–2026 Toyota 4Runner with the Old Man Emu BP-51 BP5190036R coilover strut. Designed, engineered, and manufactured by ARB’s Old Man Emu team, this right-side front strut uses advanced bypass shock technology to provide a controlled, comfortable ride on the street while delivering enhanced chassis control during off-road driving. It is engineered as a direct-fit replacement that installs without vehicle modifications, helping simplify suspension upgrades for demanding daily and recreational use.
The BP-51 combines position- and velocity-sensitive damping with an external remote reservoir for increased oil capacity and improved heat management. Its internal bypass design provides additional damping control near the ends of the shock stroke, helping reduce harshness over smaller impacts while supporting stability through larger suspension movements. Ten compression and ten rebound adjustment positions allow the shock to be tuned across a broad range for different terrain, driving conditions, and vehicle setups.
The shock body, reservoir, and key components are constructed from 6061-T6 aluminum and protected with Type III hard anodizing for corrosion resistance, heat dissipation, and improved protection against stone damage. With its 51mm internal bore, remote reservoir, and adjustable damping, the Old Man Emu BP-51 BP5190036R is a purpose-built front-right coilover strut for drivers seeking improved ride quality, suspension control, and off-road performance in a 2025–2026 Toyota 4Runner. Professional installation and alignment are recommended after installation.
