QA1 10HT250 High Travel Coil Spring 10 Inch 2.5 Inch ID 250 lb/in Rate

QA1's 2.5-inch inner diameter high travel coil springs are designed for those who demand reliable performance from their suspension, offering a balanced combination of maximum travel, consistent performance, and long-term durability whether on the track or street.

High Travel Design Benefits:

• Engineered with smaller diameter high-tensile chrome silicon alloy wire and fewer coils to compress further before reaching a solid state, allowing full use of available suspension travel without bottoming out
• Lighter weight with increased travel due to larger distance between coils, reducing unsprung weight and reacting faster to optimize suspension performance
• Up to 28 percent lighter weight and up to 20 percent increased travel compared with conventional springs
• Features a linear rate design for consistency and predictability throughout the entire stroke

Premium Construction:

• Manufactured from high-tensile chrome silicone alloy wire, keeping them lightweight without sacrificing strength
• Careful heat-treating and post-processing allows for greatly improved fatigue life, with coil design allowing compression to coil-bind without affecting spring rate or free height
• Silver powder coated finish and ground at both ends for straight, consistent and accurate operation
• Clearly marked with free length and spring rate for quick and easy identification
