Main Line Overland recently got an up-close-and-personal look at ARB’s new OME BP-51 Suspension System during an install on a customer’s 2015 Toyota Land Cruiser (200 Series). While it is no secret that MLO is an ARB distributor and very familiar with their suspension systems, the BP-51 (Bypass 51mm diameter bore) shock absorbers offer some innovations that were new to even our stalwart off-road techs.
The first thing you notice on opening the ARB box is that the BP-51 is hands-down the best looking shock system on the market. ARB spent years developing this system, and they certainly did not skimp on the finishing materials in their production models.The shock body uses aircraft grade (6061) anodized aluminium, with internal channels designed to increase dampening by allowing fluid to bypass the shock piston at the top and bottom of the piston stroke. This results in a progressively dampened shock that is both well-mannered on-road, and resistant to sudden bottoming during the rigors of off-road travel.
