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.

The Old Man Emu BP-51 shock absorber, part number BP5160078, brings advanced racing-inspired suspension technology to everyday driving and off-road adventures. Designed for the 2025-2026 Toyota 4Runner, this position-sensitive bypass shock absorber uses a remote reservoir and large-bore design to provide comfortable street manners, improved chassis control, and increased damping near the end of the suspension stroke. It installs without vehicle modifications for a straightforward upgrade to the vehicle’s suspension performance.

Developed and extensively tested by ARB’s Old Man Emu ride engineers in demanding Australian conditions, the BP-51 allows drivers to fine-tune suspension behavior for different terrain, vehicle setups, and driving preferences. Independent compression and rebound adjustments provide a broad tuning range, helping optimize ride quality, handling, and control both on pavement and over rough trails. The remote reservoir increases oil capacity and supports lower operating temperatures during sustained, demanding use.

The shock absorber body, reservoir, and key components are manufactured from 6061-T6 aluminum and protected with a Type 3 hard-anodized finish for heat dissipation, corrosion resistance, and improved resistance to stone damage. Old Man Emu manufactures BP-51 shock absorbers in-house using advanced equipment and controlled production processes to support consistent quality and performance. This automotive suspension component is designed to fit 2025 and 2026 Toyota 4Runner applications listed for this part.

Features:

  • Remote reservoir increases oil capacity and helps maintain lower operating temperatures
  • Internal bypass technology provides increased control near the suspension end zones
  • Position- and velocity-sensitive damping adjusts performance throughout suspension travel
  • Ten levels of compression adjustment support personalized suspension tuning
  • Ten levels of rebound adjustment support tailored ride and handling characteristics
  • Large 51mm internal bore supports increased damping capacity
  • 6061-T6 aluminum construction promotes heat dissipation and corrosion resistance
  • Type 3 hard-anodized finish helps protect against corrosion and stone damage
  • Bolt-on design installs without vehicle modifications
  • Fits 2025-2026 Toyota 4Runner applications
