QA1 10HT650B High Travel Coil Spring 10in 2.5in ID 650 lbs/in Black

The QA1 10HT650B High Travel Coil Spring is designed for those who demand reliable performance from their suspension, offering a balanced combination of maximum travel, consistent performance, and long-term durability for both track and street use. Manufactured from high-tensile chrome silicon alloy wire, this spring remains lightweight without sacrificing strength, making it tough enough to handle the demands of racing while still being a great fit for street driving.

Key Features:

• 10-inch free length with 2.5-inch inner diameter and 650 lbs/in spring rate
• Black powder coat finish for corrosion resistance and appearance
• High travel design engineered to maximize suspension movement range by using smaller diameter wire and fewer coils, allowing the spring to compress further before reaching solid state without risk of bottoming out
• Linear rate design for consistent and predictable suspension performance
• Reduced unsprung weight allows faster reaction time and optimized suspension performance
• Compatible with standard 2.5-inch I.D. coilover hardware

Proudly made in the USA, all QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions. This high travel spring is ideal for performance vehicles, custom hot rods, muscle cars, and street rods requiring precise suspension tuning.
