New Shocks + Full Service

Built Around Your Race Program.

NTC can put together a new Afco package for your dirt car or service the shocks already on your race program. We work with racers across the Midwest and can help narrow the choices based on class, sanction and application.

IMCAUSRAWISSOTA

Shock eligibility varies by class and sanctioning-body rules. NTC can help match the package to your application and current rule set.

NTC Shock Service

Afco service built for dirt-track racing.

NTC inspects, rebuilds and revalves Afco racing shocks and works with racers on shock selection and setup. Performance testing is available when useful to verify service work, compare shock behavior and support setup decisions.
