What is the benefit of a high travel spring?

High travel springs have fewer coils and a smaller wire diameter, allowing for greater distance between the coils. This design increases the spring's overall travel range, which can improve suspension performance and comfort by allowing the wheels to move more freely over obstacles.

What does the lifetime guarantee cover?

QA1 guarantees that these springs will remain within 2% of their original free height and spring rate under normal operating conditions. This ensures consistent performance and durability over the life of the spring.

What does 'unsprung weight' mean and why is it important?

Unsprung weight refers to the mass of the vehicle not supported by the suspension, such as wheels, tires, brakes, and the springs themselves. Reducing unsprung weight allows the suspension to react more quickly to road imperfections, leading to improved handling and ride quality.

Product Details

When you're rebuilding the suspension on a wide range of vehicles, from classic muscle cars like the Chevrolet Camaro to trucks like the GMC Sonoma, having the right coilover springs is key. This QA1 high travel spring is designed to give your suspension more room to work, allowing for increased wheel travel and better performance. It's a well-built component that helps optimize how your suspension handles bumps and road imperfections.

QA1 manufactures these springs from a specially designed chrome silicon alloy wire. This material allows for fewer coils and a smaller wire diameter compared to standard springs, making them lighter. This reduction in unsprung weight means your suspension can react faster to changes in the road surface. The material and QA1's careful heat-treating and post-processing also contribute to improved fatigue life, so the spring maintains its rate and free height over time. The ends are ground flat for consistent operation, and the spring is finished with a silver powder coat for durability.

This particular spring measures 10 inches long with a rate of 750 pounds per inch and has a 4-1/8 inch inner diameter. QA1 backs these springs with a lifetime guarantee to remain within 2% of their original free height and rate under normal operating conditions, giving you confidence in their long-term performance.
