The QA1 63 Series sealed threaded-body twin-tube shock is a serialized, dyno-tested spec shock built from aluminum with a 7" stroke and 4–4 valving. It offers a compact compressed height (13.38") and 20.30" extended height with eyelet top and bottom for common mounting. The sealed aluminum construction and twin-tube design deliver consistent feel and grip across many track conditions, and these shocks are made in the USA for controlled spec applications.
