QA1 10HT550B High Travel Coil-Over Spring 2.5in ID 10in 550 lb/in Black

The QA1 10HT550B 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 whether on the track or street. This coil spring is constructed from chrome silicon alloy wire and features a black powder coat finish, with a 2-1/2 inch inner diameter and 10 inch free length.

Key Features:

• 550 lbs/in linear spring rate for consistent, predictable performance throughout the stroke
• Constructed from high-tensile chrome silicone alloy wire, keeping the spring lightweight without sacrificing strength
• Engineered with smaller diameter wire and fewer coils, allowing the spring to compress further before reaching a solid state
• Lighter weight reduces unsprung weight and reacts faster, optimizing suspension performance
• Ground at both ends to ensure straight, consistent and accurate operation
• Compatible with standard 2.5 inch I.D. coilover hardware
• Black powder coat finish for corrosion resistance and aggressive styling

QA1's high travel springs feature a linear rate design, meaning the spring rate stays the same throughout the entire stroke, giving drivers the confidence they need in various driving conditions. Made proudly in the USA, QA1 high travel springs come with a lifetime warranty.
