QA1 9HT350 High Travel Coilover Spring 9 Inch 350 lb/in Rate

The QA1 9HT350 High Travel Coilover Spring is engineered for maximum suspension performance in both racing and street applications. This 9-inch coilover spring features a 2.5-inch inside diameter and a 350 lb/in spring rate, making it ideal for custom suspension setups requiring precise spring characteristics.

Advanced High Travel Design:

• Manufactured from high-tensile chrome silicon alloy wire for superior strength and durability
• Fewer coils and smaller wire diameter reduce weight up to 28% compared to conventional springs
• Increased travel up to 20% due to larger spacing between coils
• Linear rate design maintains consistent spring rate throughout the entire stroke
• Can be compressed to coil-bind without affecting spring rate or free height

Quality Construction and Finish:

• Silver powder coated finish provides corrosion resistance and professional appearance
• Ground on both ends for straight, consistent, and accurate operation
• Clearly marked with free length and spring rate for easy identification
• Made in the USA with rigorous manufacturing processes

Performance Benefits:

• Reduced unsprung weight improves suspension response and handling
• Enhanced fatigue life through careful heat-treating and post-processing
• Compatible with standard 2.5-inch I.D. coilover hardware
• Lifetime warranty to remain within 2% of original free height and rate under normal operating conditions

The QA1 9HT350 delivers reliable, predictable performance whether you're at the track or on the street, combining maximum travel capability with long-term durability.
