Zbroz Racing Spring Kits improve performance and control for Walker Evans Shocks and KYB Shocks.  Spring Kits are one of the most under rated and affordable suspension upgrades you can make.  When it comes to a true tuned in suspension setup, the one size fits all riders is not the answer. 

Stock suspension setups are going to be too soft for larger riders and way too soft for aggressive riders. Don't let a one-size-fit-all suspension setup limit your riding experience and progression.

By using our higher quality springs that have more progression, your Walker Evans Shocks and KYB Shocks will deliver Race Inspired Performance, Control and Bottoming Resistance. Along with Plusher Ride experience for Mountain Trail Riding, Backcountry Boondocking, Extreme Backcountry and Competitive Racing.
