QA1 12HT400 High Travel Coil Spring 12 Inch 2.5 ID 400 lb/in Rate

The QA1 12HT400 High Travel Coil Spring is designed for demanding suspension applications that require reliable performance, maximum travel, and long-term durability for both track and street use. This spring features a 12-inch length, 400 lb/in spring rate, and 2-1/2 inch inside diameter.

High Travel Design:

High travel springs are engineered to maximize suspension movement range by using smaller diameter high-tensile chrome silicon alloy wire and fewer coils, allowing the springs to compress further before reaching solid state and preventing bottoming out. The larger distance between coils results in lighter springs with increased travel that reduce unsprung weight and react faster, optimizing suspension performance.

Key Features:

• Constructed from high-tensile chrome silicon alloy wire for lightweight strength
• Linear rate design for consistent, predictable suspension performance
• Silver powder coated finish with ground ends for straight, consistent operation
• Can be compressed to coil-bind without affecting spring rate or free height
• Compatible with standard 2.5-inch ID coilover hardware
• Proudly made in the USA

QA1 high travel springs come with a lifetime warranty, ensuring quality coverage for demanding driving conditions. All QA1 springs are lifetime guaranteed to remain within 2% of original free height and rate under normal operating conditions.
