QA1 10HT850 High Travel Coilover Spring 10 Inch 850 lb/in Rate 2.5 Inch ID

The QA1 10HT850 is a 2.5-inch inside diameter high travel coilover spring 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.

Key Specifications:

• Spring rate: 850 lbs/in
• Free length: 10.000 inches
• Inside diameter: 2.500 inches
• Silver powder-coated finish
• Compatible with standard 2.5-inch I.D. coilover hardware

High Travel Design Benefits:

• Engineered to maximize suspension movement range by using smaller diameter high-tensile chrome silicon alloy wire and fewer coils, allowing the spring to compress further before reaching solid state and take full advantage of available suspension travel without bottoming out
• Linear rate design maintains the same spring rate throughout the entire stroke for consistent and predictable performance in various driving conditions
• Made of high-tensile chrome-silicon wire that reduces weight up to 28 percent and increases travel up to 20 percent compared with conventional springs

These 2.5-inch diameter coil springs are constructed from high-tensile chrome silicone alloy wire, keeping them lightweight without sacrificing strength—tough enough to handle the demands of racing while still being a great fit for street use. QA1 high travel springs are proudly made in the USA and come with a lifetime warranty.
