Ridetech HQ Series Front Coilovers for 1958-1964 GM B-Body

The Ridetech HQ Series Front Coilovers, MPN 11053510, are a complete front coilover pair for 1958-1964 GM B-Body cars, built for direct bolt-on installation when paired with Ridetech StrongArm lower control arms. Each shock uses a billet aluminum body with a 3.6 inch stroke and a 12-position rebound adjustment knob, matched to an 8 inch, 750 lb/in progressive-rate Hyperco coil spring. The kit allows about 1.5 inches of drop below stock ride height and uses cadmium-plated steel hardware for corrosion resistance.

  • 3.6 inch shock stroke
