Ridetech front HQ Shockwaves for 1957–1960 Cadillac are a pair of rebound-adjustable shocks meant for use with stock lower arms, supplied with 1/4" airline fittings. They deliver air-adjustable damping tuned to late-1950s Cadillac front suspensions, allowing owners to refine ride characteristics and integrate air control into classic rebuilds without extensive modification to lower-arm mounting.
