Those BP-51 look interesting. Wonder what they bring that FOX, Icon, King don't already, particularly for front coil overs. They apparently use a 51mm bore. My FOX 2.5" body shocks have a 2.268" diameter working piston, or about 57.6mm, but I don't know if that's what OME is talking about. A 2.0" body is 51mm externally and the working piston is therefore about 45mm, so that would put the BP-51 somewhere between a 2.0 and 2.5 shock I guess.
The rear shocks look to have a couple of external adjustments, so that would be handy. I have smooth body FOX non-bypass shocks and sometimes I think the valving is dead-on and sometimes it's under damped. Been looking at doing FOX shocks with remotes and the adjusters because of that. I wonder how well those will stand up to dirt and mud, but I like the idea of having easily adjustable compression and rebound for the rear since the cargo changes dramatically between uses.
One thing is for sure, it's not any cheaper to do a full BP-51 kit over the equivalent FOX, Icon or King. The front coil overs go for $1,600 and the whole BP-51 kit is $3,200. The very top end FOX and King front 2.5 remote, external adjuster coil overs sit at $1,700 and I can't see OME being on that level, honestly.
