Racer Tech has been developing and producing spring replacement kits for various UTV models including the Polaris RZR since 2007. With thousands of kits sold now they’ve proven to have a good set-up. These springs replace the very poor OEM springs with these high-quality U.S.A. made custom engineered springs. Racer Tech has pioneered a new type of dual rate spring design they call D.I.S.S. It’s a very unique design and it results in massive reduction in rear-end “bucking” and improves ride and handling at the same time. Racer Tech actually guarantees their springs are better than any other spring on the market. The best part is they are reasonably priced and get back that lost ride height too! They sell kits for all RZR models and recently released kits for all Can-Am UTVs as well. For more info, see www.RacerTech.com.
