QA1 79-93 Ford Mustang Proma Star Coilover Strut Single-Adj 14.05 - HS01

Product Overview The QA1 Proma Star Strut is a perfect choice for your Mustang. It's ideal for both street and race applications, thanks to its lightweight inverted strut design. This allows you the best possible performance and handling out of your car, regardless of your driving style. Inverted Strut Design A major advantage of the Proma Star strut is its inverted cartridge design. Unlike conventional designs, its large diameter shaft resists side loading, ensuring smoother and more consistent performance during hard cornering and braking. The lightweight threaded aluminum body offers reduced unsprung weight improving suspension responsiveness, leading to better handling and traction. Single-Adjustable Valving Single-adjustable struts are a good option for street-driven cars that also see occasional track use. Rebound adjustment is made under the hood with an easily accessible 18 position knob at the top of the strut tower. A good choice for drivers wanting a comfortable ride on the street with the ability to firm up the suspension to hit the curves. Easy, Bolt-In Installation Our commitment to thoughtful product design is evident in every fully bolt-in kit we produce, which guarantees a hassle-free installation process. Made in the USA QA1 Proma Star struts are proudly made in Lakeville, Minnesota. Fitment Notes Includes one individual strut only.
