Old Man Emu BP5190036L BP-51 Front Left 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 or 2026 Toyota 4Runner with the Old Man Emu BP-51 Coilover Strut, part number BP5190036L. Designed for the driver-side front position, this remote-reservoir strut combines comfortable on-road handling with enhanced control during demanding off-road driving. Its bolt-on design installs without vehicle modifications, making it a practical suspension upgrade for overland travel, trail use, and everyday driving.
The BP-51 uses internal bypass technology with position- and velocity-sensitive damping to provide increased control through the suspension’s end zones. Ten levels of compression adjustment and ten levels of rebound adjustment allow the ride to be tuned across a broad range of conditions, vehicle loads, and driving preferences. The remote reservoir increases oil capacity and helps manage operating temperatures for consistent damping performance during extended use.
Old Man Emu manufactures the BP-51 using a 6061-T6 aluminum body, reservoir, and key components. Type 3 hard anodizing improves corrosion resistance, heat dissipation, and protection against stone damage. Developed, tested, and manufactured under ARB’s Old Man Emu engineering program, the BP-51 is built to deliver dependable suspension performance on both pavement and rough terrain. This front-left coilover strut is designed specifically for compatible 2025-2026 Toyota 4Runner applications; verify vehicle configuration and suspension requirements before installation. California Proposition 65 warning applies.
