4x4proyect.com.com show us fixing kits VM80010021 for remote reservoir of the new Rear BP-51 Bypass Shocks. For Nissan Patrol Y62. The new BP-51 range of high performance, bypass shock absorbers is the result of an exhaustive development process aimed at delivering the ultimate in both comfort and control. Designed, developed and tested entirely in-house by ARBs team of Old Man Emu ride engineers, BP-51 shock absorbers are vehicle specific and utilise existing mounting locations to provide easy installation without the need for additional vehicle modification. Unlike most other adjustable shock absorbers, which provide adjustment for compression only, the BP-51 range allows on vehicle, independent adjustability of both rebound and compression to offer class leading ride customisation that can be tailored to individual vehicle or trip requirements.
