EXTRA COMFORT – BOTH ON AND OFF BOARD

Old Man Emu’s Ride Control Engineers spent countless hours in design and testing to ensure Nitrocharger valving is precisely matched to an OME spring selection that is right for the accessories fitted to your vehicle, as well as your load requirements.

Testing is carried out both in the field with sophisticated data logging equipment, as well as inside the OME laboratory using shock dynamometers to ensure durability under all conditions. With Nitrocharger’s vehicle specific valving technology, owners will experience improvements in both ride control and comfort whether it be on or off road.

3 Years Warranty

ARB prides itself on creating the best products that offer quality, reliability and practicality above all else. Naturally all ARB products manufactured and distributed by us come with a three years nationwide warranty.

Closer Look

The Old Man Emu BP-51 suspension kit represents the pinnacle of 4x4 suspension performance, integrating racing-derived internal bypass technology with user-adjustable damping. Engineered to provide a tailored, balanced solution, this system significantly improves your vehicle's ride, handling, and load-carrying capabilities across Australia's diverse terrains.

At the heart of the BP-51's revolutionary performance is its patented, position-sensitive internal bypass damping technology. This allows for a plush and comfortable ride in the normal zone, progressively firming as it approaches travel limits to prevent harsh bottoming and topping-out. External rebound and compression adjusters offer complete control, enabling you to fine-tune your vehicle's handling for any load or terrain. Manufactured in-house by ARB from aircraft-grade 6061 anodised aluminium, BP-51 shock absorbers ensure superior heat dissipation and corrosion resistance, with remote reservoirs increasing oil volume for unparalleled control and comfort.

Complementing the BP-51 shock absorbers, this kit includes Old Man Emu coil springs, specifically designed to withstand Australia's rugged conditions. Crafted from state of the art micro-alloyed spring steel, these springs offer superior resistance to sagging and corrosion. Available in constant and variable rates, they are perfectly matched to your specific load requirements and intended vehicle usage, while also delivering enhanced ride control.

To ensure seamless installation and optimised performance, the kit incorporates a range of essential Old Man Emu fitting components. This includes application-specific BP-51 front and rear fit kits, an OME gearbox packer to adjust drive shaft angles for lifted vehicles, and an OME caster kit to correct geometry and improve steering precision after a lift. An Old Man Emu steering damper is also included, featuring a 35mm piston and bore, twin tube design, steel stoneguard, and foam cell technology to provide enhanced steering control and protection against impacts.

Developed and tested in Australia's punishing conditions, this Old Man Emu BP-51 suspension kit provides an integrated solution that delivers exceptional performance, comfort, and durability, giving you the confidence to explore further and return safely from any adventure.
