Rocky Road offroad makes rock rails/sliders for the VX, I think they're the only ones. IIRC everybody else made them/had theirs custom made.
Myself and vt_maverick currently are the only two I know who have them right now.
We both have the "Super Sliders" they offer. No trimming of cladding was required.
Can see I sure broke them in this year on Moab!

CAN SEE THE END OF THE SLIDER COMES RIGHT UP TO END OF CLADDING, SO NO CUTTING NEEDED.

edit...oh forgot to mention, all that orange stuff everywhere is good ole' AZ desert dust...not rust...
