The QA1 Proma Star coil-over shock brings coil-over performance to a wide range of vehicles, including custom chassis and suspension builds where direct fit options are not available. It uses a single adjustable valving design that softens or stiffens the overall ride with one knob, which suits street driving. The threaded body and included hardware kit allow quick and easy ride height adjustment, and a 2.5 inch spring of the appropriate length and rate completes the setup. Each Proma Star shock is made in the USA and dyno tested, and is covered by a limited lifetime warranty when registered before installation.
