All of our proprietary springs are made in the USA from the highest quality CrSi materials. This means they are always the exact rate we want and don’t fade or break. They cost more when made from this material but are absolutely worth it when it comes to function and longevity. They are also warrantied for life! Powder coating the springs will void the lifetime warranty*

Made a world of difference and very easy to install! Wish I would of done it sooner.
Your shock spring set made a huge improvement. Our whole riding group has them installed now!! Amazing work guys!! Thank you!!
I recently installed a spring kit on my XP turbo, I ride mainly trails and rock and some mud. With the pre-load and cross over rings set to the measurements you provide this machine is amazing now. Not only does it ride better, the handling and traction is improved greatly! Thanks for doing things right!
Definitely an improvement from my factory springs, although i had higher expectations they are ok tho!! Think my biggest disappointment was no stickers included!! Key chain, shirt, beer coozy...nothing but springs
Night and day difference over stock! Very pleased!!!!!!!
Very happy with product. Improved ride tremendously
Best upgrade yet!! Worth every penny
Absolutely the best upgrade you can do . We mainly ride hill country and we added alot of stuff to our car and realy had it riding like a slug. But shock therapy came threw and fix us up. Rides by far better than shock and got my ground clearance back. Will definitely use them from now on.
This spring set is definitely the best investment anyone could do on their machine. Everything fit perfectly. And the ride is amazing now. It actually feels like the $20k machine I paid for. Only thing I couldn’t find was preload and crossover specs for a Dynamix model. But I just set the ride height and went from there. Thanks guys and keep up the great work!
