JFOYH Coil+Oil Shock Absorber Adjustable Damping Hydraulic Rear Shocks for MTB/E-Bike/Scoters, 125MM/150MM/165MM/190MM 550LBS/650LBS/1000LBS/1500LBS - 125MM*650LBS

I got the 150MM one. Works well, but the red adjustment knob for controlling the springback fell off and I can't find a replacement one. My rating would be higher if this simple annoying issue was easier to solve....

Works great nice item I say

Good rebound damping.

Mounted this on a 5 year old Iron Horse 29er that still had the original coil shock with hundreds of miles on it. I’d put an air fork on the bike a couple years ago and that’s been a great upgrade. But I didn’t want to deal with an air shock in back…for the terrain I ride, it’s just not worth all the pedal bob and servicing that come with air. This hits the happy medium. Practically no pedal bob due to a heavier spring, but with the rebound cranked way down, it sucks up a lot of the bumps comfortably and without the pogo stick effect of a basic coil spring. Especially on areas where any kind of tracked vehicle has left washboard terrain in its wake. And it should be pretty much maintenance free beyond cleaning it now and then. I’d make sure to grease the bushings and bolts before install. Came with two standard short 8mm bolts and one longer bolt for mounting to the rear rockers.

I bought these to modify and install on my Ecomobl M24PRO electric skateboard. 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.
