QA1 10HT500 High Travel Coilover Spring 2.5" ID 10" Length 500 lb/in Rate

The QA1 10HT500 is a high-performance coilover spring engineered for maximum suspension travel and consistent performance in both racing and street applications. This 10-inch high travel spring features a 2.5-inch inside diameter and a 500 lb/in spring rate, making it ideal for demanding suspension setups that require reliable performance without bottoming out.

Advanced High Travel Design:

QA1's high travel springs are manufactured from high-tensile chrome silicon alloy spring wire, which allows for fewer coils and a smaller wire diameter compared to conventional springs. This innovative design provides up to 20 percent increased travel and reduces weight by up to 28 percent. The increased spacing between coils allows the spring to compress further before reaching solid state, maximizing your available suspension travel. These lighter springs also reduce unsprung weight and react faster, optimizing overall suspension performance.

Key Features:

• 10-inch free length with 500 lb/in linear spring rate
• 2.5-inch inside diameter compatible with standard coilover hardware
• High-tensile chrome silicon alloy construction for superior strength
• Silver powder coated finish for excellent durability and corrosion resistance
• Ground at both ends for straight, consistent, and accurate operation
• Clearly marked with free length and spring rate for easy identification
• Cold wound, double heat-treated, and shot peened for consistency
• Can be compressed to coil-bind without affecting spring rate or free height

Quality Assurance:

Proudly made in the USA, all QA1 high travel springs are backed by a lifetime warranty to remain within 2% of the original free height and rate under normal operating conditions. Each spring undergoes intensive manufacturing processes including careful heat-treating and post-processing to ensure consistent performance and greatly improved fatigue life.
