Mustang II Coil Spring - 2.5/3.5 x 8 500#

The Mustang II Coil Spring – 2.5/3.5 x 8 500# by QA1 is a specialized suspension component designed for vehicles utilizing a Mustang II-style independent front suspension. This coil spring is ideal for hot rod builds, restomods, or modern chassis adaptations to classic car proportions, providing the necessary support for controlled ride height and load distribution.

With a spring rate of 500 lbs/in, paired with 2.5-inch inner and 3.5-inch outer coil diameters and an 8-inch free length, this spring is suitable for mid-travel suspension architectures where controlled spring force is essential. The design is intended to absorb small road irregularities while maintaining stiffness during dynamic cornering and braking events, ensuring a reliable performance.

Mechanics and fabricators engaged in Mustang II spindle conversions, kit car platforms, or custom chassis builds will find this spring particularly beneficial for front-end applications that require a moderate spring rate for optimal weight distribution. For best results, it should be paired with quality dampers that complement the 500 lbs/in rate.
