OME BP-51: Bolt-on Bypass Shocks for Insane PerformancePosted in News on November 5, 2014
ARB has taken off the gloves and entered the super-high-end shock fray with its Old Man Emu BP-51 Bypass Ride Control shock, which it unveiled at the 2014 SEMA show. As the name alludes, the BP-51 is an internal bypass, remote reservoir shock with an enormous 51mm piston, a lightweight 6061 T6 aluminum hard-anodized body, and a very trick on-vehicle adjustment feature to dial in the compression and rebound to site varying loads, driving styles, or terrain.
The OME engineers begin with an application-specific valve stack atop the huge 51mm piston. The shocks are rebuildable and can be revalved, but the the built-in compression and rebound adjustments we can't see where that would be necessary. An included spanner wrench is used to dial the compression and rebound up or down on the vehicle. Once installed, there's no need to remove the shocks for fine-tuning.
We saw two popular applications on display in the ARB booth that were indicative of the different shock designs: a Tacoma shock-in-spring coil over including an OME lift coil, and a JK Wrangler version. And yes, plan on seeing these shocks packaged with OME lift coils for a complete bolt-on high-performance suspension you don't need to cut, weld, or make chassis modifications to realize. And OME is working on applications to cover it's catalog.
The adjustable internal bypass feature is a real marvel of machining, requiring the development of special tooling, but the end result should work insanely well. We'll bring you a further update on the BP-51's performance as soon as we can get our hands on them.
