Description

The QA1 10GC300 is a premium coil-over racing spring engineered for high-performance street and track applications. This 10-inch spring features a 300 lb/in spring rate, making it suitable for a variety of suspension setups where consistent, linear compression characteristics are critical for predictable handling.

Key features include a 10-inch free length with a 300 lb/in linear spring rate, manufactured from high-strength chrome-silicon alloy wire. The spring is shot-peened and heat-treated for consistency and fatigue resistance, with ends that are ground flat for accurate operation. It is available with a powder-coated or chrome finish for corrosion protection and appearance.
