Description

QA1 Proma Star externally adjustable coilover shocks and struts provide just the right combination of consistency, reaction, and durability for drag racing. They have special valving, which is designed to compensate for high shaft speed, while allowing for low shaft speed control. When combined with the 18 externally adjustable valve settings, they ensure an improved grip on the track from end to end. Other features include a bright-anodized aluminum body, PTFE-lined bearings or polyurethane bushings, a 5/8 in. centerless-ground chrome piston rod, and aerospace-caliber sealing materials.

Product Overview

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. QA1 Caster Camber plates are required and sold separately. 79-89 Mustang CC110 90-93 Mustang CC112 Coil over conversion kits available as COK113 79-93 Fox Body applications work on wide and narrow spindles.
