Great for Roadrunner Pro
These fit nicely on my Voro Roadrunner pro. The ride is much improved over the stock shocks and they don’t bottom out. Changing the spacers was a bit of a pain, but I was able to hammer the ones preinstalled with a socket and a hammer. Overall I would highly recommend these for the RR pro.

Good value for the price
Great product ! I used it on a 2seater yerf dog go cart, I went from bouncing out of the seat to being able to stay on the gas in curbs and being adjustable was a huge plus I left the rear soft and 1 turn on the front for when riding with passengers

Great product for the price and my son loves the color of these on his white 4wheeler! They have held up two years so far and are doing good. Installation was easy and fit great

Coleman b200rsv with some added parts+
With some extensions, nuts and bolts and a little know how I was able to fit it to my Coleman b200rsv! Helped with the ride and is much higher off the ground. I got the pivot relocation from Amazon. I got the chain and the tool for the linking the chain from Amazon and I just got the nuts and bolts from my local hardware store.

They fit and look great! The ride is much smoother. It lifted the back end up a little I'm 5'11 it just feels better all around. Good product I'd recommend and buy again if needed.

You get what you pay for…
Garbage. Spent an hour trying to adjust the coil over, only went down about 1/4 in. I got 2 sets and all the same…

Too stiff for Honda Monkey
I weigh 180 pounds and these are far too stiff for 2020 Honda Monkey. Less suspension travel as well
