They didn't know when additional parts… They didn't know when additional parts that they sale would be available and couldn't even provide a time frame when they would be available.

The product was great quality The product was great quality! The installation however was another story. The video installation tutorials are great but they have not kept them up to date with either new models of UTV's or changes that they have made in their product line. I reviewed their site and read the written instructions but unfortunately those were not up to date either and seriously lacked photos. This left me guessing as to where to place some of the updated parts. In short great product but not everyone is a mechanic so poor score for execution.

Just installed my level 4 dual rate… Just installed my level 4 dual rate springs last night on my 2017 Polaris RZR XP 1000. Will try them out on trails this weekend. Online order experience was good, with prompt shipment. Quality looks good, everything fit correctly and online instructions made install easy.

Easy to navigate website Easy to navigate website. Fast delivery. My opinion-- On Turbo RZP XP. No reason Fox Edition springs should cost more than Walker Evans spring set up.

Product seems good Product seems good, not much use yet. Shock therapy has some of the worst customer service I’ve dealt with. Got my spring kit and needed some help so I called and they told me they don’t make the kit that they sold me and that their directions are more of a guide line and you can’t really follow them.
