FWIW... I recently replaced (old and rusted) OME nitros with new OME Nitro-sports on two trucks, and experienced very notable results.
On my FZJ80 the new dampers were a much needed and welcome improvement. This is an overland truck based in Central America which carries near 1500# of armor, tools, spares, and luggage on routine basis; and rarely sees tarmac. The damping on the new sports is well matched to the 863J springs, under load. The truck handles great on all types of gravel, washboard, sand and mud; and settles in quick after big hits or jumps. Feeling lots of love in this application
On my UZJ100, not so much love with new sports compared to old nitros
I run 865 springs in rear and OME T bars up front with sliders. This truck is used for occasional towing, some 4 wheeling, some camping, and daily driver with monthly trips to Costco. The shocks, w/o at least 500# cargo, way over dampen compared to the medium duty springs. They definitely add stiffness to the suspension and take away from ride comfort and articulation off road. Add 1000 of cargo and passengers and they are fine, but they are not a comfortable ride for a no to low loaded 100. The older nitro (non sports) were valved more appropriately for a daily driver and/or 4 wheeler. Not a bad shock, just not right for this application. Going to explore Radflo 2.5" and/or Koni Raids
