Mustang II Coil Spring - 2.5/3.5 x 8 600#

The QA1 Mustang II Coil Spring 2.5/3.5 x 8 600# is designed for builders and enthusiasts looking to modernize classic Mustangs with independent front suspension geometry. This coil spring is a vital component for Mustang II-based front-end conversions, providing essential ride height control and load support for street-driven restorations and vintage racing applications.

With a spring rate of 600 pounds per inch, this QA1 coil spring features a 2.5-inch inner diameter and a 3.5-inch outer diameter, with an 8-inch length when fully compressed. This design is ideal for tight engine bays and low-stance setups typical in vintage performance builds. The spring's rate strikes a balance between street comfort and handling precision, effectively resisting excessive body roll during cornering while maintaining compliance over bumps.

Fabricators, restorers, and track-focused builders will find this spring's compact design and load rating beneficial when integrating modern suspension geometry into classic platforms. Its construction adheres to QA1's high manufacturing standards, ensuring consistent wire diameter and coil spacing to prevent premature sagging and deliver predictable suspension behavior across thousands of heat cycles.
