Acrotech Inc. Supplies multiple race car teams with a little known part that helps dial in race car suspension for specific tracks and conditions. The urethane spring rubber insert. Sometimes changing out a spring in favor of height and rate can take more time than what is available. This is evident when it comes time to pit the car, when time is of the essence a simple removal or swap of a spring rubber to help dial in feel and dampening can make the difference on a podium finish or not. Our urethane spring rubbers are highly customizable for many common sized springs. The durometer or hardness of the urethane will increase the spring rate a little bit (40A Durometer) or a lot (95A Durometer) effectively without swapping springs. Testing or trial and error is case by case, we recommend to start with several sets in different durometers to test for your vehicle on your track. Wether it be Nascar® or your local dirt racing track. Get the edge over the competition and call us for urethane spring rubbers. Contact us for a Quote.
