QA1's GM Front Pro Coil System delivers fully adjustable ride height and valving control for full size GM and Ford applications. A fully threaded shock body sets the ride height for the desired stance and helps fine tune weight balance, while the lightweight billet aluminum coil-over shocks offer single adjustable valving. The specially designed high travel springs use fewer coils and a smaller wire diameter for added travel, reduced unsprung weight and faster response. Each system installs with basic hand tools, is 100 percent dyno tested and serialized, and can be serviced and rebuilt by QA1 authorized service centers. Made in the USA and sold in pairs.
