BP-51 (BYPASS 51MM DIAMETER BORE) SHOCK ABSORBERS

Introducing the BP-51 range: a game-changer in high-performance bypass shock absorbers. After an extensive development process, the team at Old Man Emu have nailed the perfect blend of comfort and control. Our team of Old Man Emu ride engineers at ARB designed, developed, and tested these shocks entirely in-house, ensuring top-notch quality and performance.

The BP-51 shock absorbers are vehicle-specific and use your vehicle’s existing mounting points. That means you can easily install them without needing extra modifications.

Unlike other adjustable shocks that only tweak compression, the BP-51 shocks let you adjust both rebound and compression independently, right on your vehicle. This means you can fine-tune your ride to suit your specific needs, whether you’re gearing up for a rugged off road adventure or a smooth highway drive. The BP-51 range gives you the ultimate in-ride customisation, perfectly tailored to your vehicle and your journey.

For the ultimate in performance, suspension and control, upgrade your ride with the Old Man Emu BP-51 shock absorbers. Visit your nearest ARB store or stockist today, or explore our range of Old Man Emu 4×4 suspension online.

 
 

BP-51 BYPASS TECHNOLOGY: HOW IT WORKS

Most shock absorbers use velocity-sensitive damping, where the faster the piston moves, the higher the level of damping generated. The BP-51 shock absorbers enhance this by also generating damping dependent on the position of the piston within the shock absorber’s body, via their bypass design. 

While most shock absorbers only generate damping based on fluid flowing through the piston, the BP-51 offers an alternative path from one chamber to the other, around the piston in the form of bypass passages. Some fluid flows through the piston and some fluid bypasses around the piston in the bypass passages. This results in an ability for the shock absorber to provide the best of both worlds, with a comfortable and compliant ride during normal driving and a more controlled ride over more challenging terrain. 

With greater levels of damping generated at each end of the stroke, the piston slows as it approaches full compression and extension, preventing harsh topping out against the bump stop and allowing larger bumps and corrugations to be absorbed more easily.

ABOUT THE DEVELOPMENT AND MANUFACTURING PROCESS

All BP-51 shock absorbers are manufactured in-house by ARB. In order to achieve this, we’ve invested in state-of-the-art machining and hard anodising equipment, giving us total control of the process to ensure the highest possible quality. 

BP-51 shock absorber bodies are manufactured using aircraft grade (6061) anodised aluminium to dissipate heat more efficiently than steel or alloy steel and provide superior corrosion resistance. Extensive lab testing, real world testing and destructive testing have been undertaken during development to ensure that reliability, longevity and performance all meet ARB’s impeccable standards.

  • How do BP-51 Shock Absorbers enhance my off road experience?

    With their adjustable compression and rebound damping settings, our BP-51 Shock Absorbers provide a customised ride experience. This means you can fine-tune your vehicle’s suspension to handle rough off road trails more comfortably and with better control, making your adventures smoother and safer.

  • What are BP-51 Shock Absorbers made from?

    Our shocks are made from aircraft-grade aluminium, which enhances heat dissipation, keeping the shocks cool even under extreme conditions. Plus, it’s incredibly durable and resistant to corrosion, which means it lasts longer and performs better. The shock absorber body itself is robust and designed to withstand harsh conditions.

  • Can I install BP-51 Shock Absorbers myself, or do I need professional help?

    BP-51 Shock Absorbers are designed for bolt-on fitment, meaning they can be installed without any vehicle modifications. If you’re handy with tools and have some experience, you can likely install them yourself — but we recommend heading to your nearest ARB store or stockist for precise, hassle-free installation.

  • How do I adjust the settings on BP-51 Shock Absorbers?

    Adjusting the BP-51 Shock Absorbers is pretty straightforward. There are easy-to-access knobs for both compression and rebound damping. This allows you to tweak the settings to match your driving conditions, whether you’re on a smooth highway or a rocky trail. This fine-tuning delivers increased comfort and control, tailored to your specific needs.

  • What makes the internal bypass design so effective?

    The internal bypass design in BP-51 Shock Absorbers is key to their superior performance. It allows for additional damping zones within the shock, which helps to smooth out the ride and reduce harsh impacts. This design is particularly beneficial when navigating uneven terrain, as it provides better control and comfort.

  • Are BP-51 Shock Absorbers compatible with my vehicle?

    BP-51 Shock Absorbers are available for a wide range of 4×4 vehicles.
