WE ALSO WORK ON AST, MOTON, PENSKE, MEGAN RACING, BILSTEIN AND MORE! What does that mean to you? It means you can: Buy KONI shocks and struts from ProParts USA built to your unique specifications and requirements. Have your KONI shocks and struts converted to single- or double-adjustables. Convert your adjustable KONI shocks and struts from internal to external adjustments. Dyno test your shocks and struts to be sure they stay at peak performance. Get your shocks or struts custom valved to better perform for your race application. Dyno Testing -- We use a state-of-the-art Roehrig shock dyno to thoroughly test a number of performance parameters through a wide variety of conditions. Using computer analysis, we're not only able to determine if your shocks are functioning properly, we're also able to compare different valving setups and establish the best damping settings for your shocks and struts. Every customer receives a computer printout documenting their shock's performance when it leaves ProParts USA. Revalve Service -- To work properly, the damping rate of your shocks and struts must be matched to the spring rate and weight of your car. When you upgrade your springs or alter the unsprung weight of your car, you should also upgrade your shocks. ProParts can revalve your shocks and struts to suit nearly any application. Conversions -- ProParts can convert your current shocks and struts in any number of ways. Standard shocks can be converted to adjustables, with either internal or external adjusting mechanisms. Rebound-adjustable shocks can have an adjustment added to allow for external compression adjustments as well. Need new grooves cut in the shock body to change spring perch height? No problem. Need a welded spring perch modified? No problem. ProParts is equipped to custom design virtually anything needed to modify your shocks and struts.
