QA1 9HT180 High Travel Coilover Spring 2.5" ID 9" Length 180 lb/in Rate

The QA1 9HT180 is a high-performance coilover spring designed for demanding suspension applications in racing and high-performance vehicles. This high travel spring features a 2.5-inch inside diameter, 9-inch free length, and a 180 lb/in spring rate, making it ideal for circle track, drag racing, and street performance applications.

Advanced High Travel Design:

• Manufactured from high-tensile chrome silicon alloy wire for superior strength and durability
• Fewer coils and smaller wire diameter design increases suspension travel up to 20 percent compared to conventional springs
• Reduces unsprung weight up to 28 percent for faster suspension response and improved handling
• Linear rate design ensures consistent and predictable performance throughout the compression cycle
• Can be compressed to coil-bind without affecting spring rate or free height

Premium Construction and Finish:

• Silver powder coated finish for corrosion resistance and long-lasting appearance
• Ground flat on both ends for straight, consistent, and accurate operation
• Clearly marked with free length and spring rate for quick identification
• Compatible with standard 2.5-inch ID coilover hardware
• Made in the USA with intensive quality control processes

Quality Guarantee:

QA1 backs this spring with a lifetime guarantee to remain within 2% of the original free height and rate under normal operating conditions. Each spring undergoes careful heat-treating and post-processing for greatly improved fatigue life and consistent performance over the long haul.
