The board has 4 wheel double wishbone suspension and 165MM was the exact length of the factory shocks and springs. I ordered these with the lowest spring rate I could get and sourced 150LB springs that would work with them because the 650lb were way too stiff. I like them so much I bought a set of EXA 290's as a drop in replacement for my Propel X4S. Both boards had hollow shocks from the factory and the ride is incredibly improved with these! The board feels more stable, and being a skateboard, the deck stays flatter over undulating terrain so the rider isn't having to compensate for steering upsets with their feet. Thanks to these characteristics it's not nearly as fatiguing to ride fast over rough terrain and I don't get off with sore feet! I'm not sure what people mean that their rebound adjuster doesn't work, mine makes a huge difference and I leave it as fast as I can in those application. I liked them so much I basically bought them twice, the 290's were a drop in for the Propel which came stock with 260's, from what I can see EXA 290 and 291R like these only differ by the rebound adjustment knob.
