ProParts USA is a factory authorized KONI Service and Rebuild Center.
What does that mean to you? It means you can now:

• Buy KONI shocks and struts from ProParts 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 KONI shocks and struts to be sure they stay at peak performance.

• Customize mounting hardware for one-of-a-kind applications.

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.

Revalve Service -- To work properly, the damping rate of your shocks and struts must be matched to the spring rate and weight of your race car. When you upgrade your springs or alter the unsprung weight of your race 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. The machine shop at ProParts is equipped to custom machine virtually anything needed to modify your shocks and struts.
