Product Summary

Stock Height Suspension Height Adjustment, Adjustable

The QA1 Proma Star Strut is designed for both street and race applications, featuring a lightweight inverted strut design that enhances performance and handling for your Mustang.
The strut's inverted cartridge design includes a large diameter shaft that resists side loading, resulting in smoother and more consistent performance during cornering and braking. The lightweight aluminum body reduces unsprung weight, improving suspension responsiveness.
These struts feature independent tuning for rebound and compression, allowing precise handling adjustments for various driving conditions. An easily accessible 18-position knob makes it convenient to adjust settings.
The kit includes one individual strut and requires QA1 Caster Camber plates, sold separately. It fits 79-93 Fox Body applications on both wide and narrow spindles but is not compatible with factory size springs for 2005-2014 Mustangs.
This strut is aimed at drivers seeking optimal handling and performance, making it a top choice for those serious about enhancing their vehicle's suspension.
