The BP-51 is a user adjustable internal bypass 4WD shock absorber that delivers increased comfort and control; both on and off road.

All BP-51 shock absorbers are designed and manufactured in-house by ARB using state of the art machining and hard anodising equipment.

The body of a BP-51 shock absorber is manufactured using 6061 anodised aluminium to dissipate heat more efficiently than steel or alloy steel and provide superior corrosion resistance.

Extensive dyno, real world and destructive testing has been undertaken during the development process to ensure that reliability, longevity and performance all meet ARB’s impeccable standards.

Why upgrade your suspension?

When a vehicle manufacturer designs a 4WD, they’re designing it for a mass market that has a variety of uses for that vehicle.

It may be a daily driver picking up kids from school and doing the grocery shopping, it could be a tradesman’s vehicle carrying a variety of tools and equipment, or it could be a touring vehicle towing a camper, caravan or boat.  Additionally, it could be a weekend warrior, tackling harder off road tracks and trails. Hours, weeks, months and even years have been spent developing and testing that vehicle and to be able to satisfy the varied uses, many aspects of the design of that vehicle become compromised.

A vehicle’s suspension system is one area that is compromised between the need to carry additional loads while retaining high levels of comfort and precise handling characteristics as expected in today’s modern vehicles.

Limitations of standard suspension. 

If you’re planning to drive your vehicle in its standard configuration, there’s nothing wrong with using factory supplied OE suspension.

Ultimately, the suspension has been designed to do a job and it will do so for many thousands of kilometres. However, if you are planning on modifying your 4WD with a range of accessories, plan to carry regular constant loads, tow a trailer or need more ground clearance for that off-road adventure, the O.E suspension on your vehicle may not necessarily be the best solution.
