QA1 10HT275 High Travel Coilover Spring 10 Inch 275 lbs/in 2.5 Inch ID

The QA1 10HT275 High Travel Coilover Spring is engineered to maximize suspension travel without compromising durability or performance. This 10-inch coilover spring features a 2.5-inch inside diameter and a 275 lbs/in spring rate, making it ideal for both track and street applications where reliable suspension performance is critical.

High Travel Design:

Manufactured from high-tensile chrome silicon alloy wire with fewer coils and a smaller wire diameter, this spring compresses further before reaching solid state, allowing you to take full advantage of your available suspension travel without the risk of bottoming out. The larger spacing between coils increases travel up to 20 percent compared to conventional springs while reducing weight by up to 28 percent.

Key Features:

• 10-inch free length with 275 lbs/in spring rate
• 2.5-inch inside diameter compatible with standard coilover hardware
• Linear rate design for consistent, predictable performance throughout the entire stroke
• High-tensile chrome silicon alloy construction for maximum strength and reduced weight
• Silver powder coated finish for corrosion resistance
• Ground ends on both sides for straight, consistent, and accurate operation
• Clearly marked with free length and spring rate for easy identification
• Reduced unsprung weight for faster suspension response and optimized performance

Quality and Warranty:

Made in the USA and backed by QA1's lifetime warranty, this spring is guaranteed to remain within 2 percent of the original free height and rate under normal operating conditions. The careful heat-treating and post-processing ensure greatly improved fatigue life, and the coil design allows the spring to be compressed to coil-bind without affecting spring rate or free height.
