These QA1 GM Pro Coil Systems are available for 1963-1982 Corvettes and for 1958-1970 Full Size Chevrolet vehicles, including Impalas, Bel Airs and Caprices. They are a great option for anyone looking for fully adjustable ride height and valving control. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling.
Specially designed for QA1's Pro Coil Systems, the American-made lightweight high travel springs have fewer coils and a smaller wire diameter, resulting in increased travel due to the larger distance between the coils. They reduce unsprung weight and react faster, optimizing suspension performance. Multiple spring rate options are also available and have been successfully tested in various applications, from casual street driving to hard core race applications.
Additional MOD Series Features:
Features QuickTune technology - modular valve packs that allow for completely revalving the shock without having to remove it from the car!
Medium compression and rebound valve packs standard
Soft or firm compression and rebound valve packs also available
24 click independent compression and rebound adjustment with low-speed bleed
Large solid piston (with blow-off valve) for improved driver feel and control with up to 1,600 lb. force
High-speed valving adjustment (coarse adjustment)—relates to shock operation during impact events, like hitting a pothole or curb
Low-speed valving (fine-tune adjustments)—adjusts ride quality and weight transfer on corner entry/exit; more bleed for softer feel and less bleed for stiffer feel
Indexable base eyelet—multiple mounting position to optimize knob access and provide more mounting flexibility
Made to be used with bottom eyelet style mount in tubular control arms
Thrust bearings included
NOTE:
These recommendations are general guidelines only. The weight of the vehicle, personal ride preferences, etc. need to be taken into account when selecting spring rates
