QA1 2-1/2in ID High Travel Spring - 12in Length x 275lbs/in - Silver Powder Coated

QA1 is well-known for making performance suspension components, and this high travel coilover spring is a great example of their work. This particular spring measures 12 inches long with a rate of 275 pounds per inch, designed for applications where maximum suspension travel is key. It features a 2-1/2 inch inner diameter, fitting many common coilover setups.

This spring is constructed from a specially designed high-tensile chrome silicon alloy wire. This advanced material allows for fewer coils and a smaller wire diameter, making the spring lighter and increasing the distance between coils for improved travel. Reducing unsprung weight helps your suspension react faster, which can optimize overall performance. The chrome silicon steel, combined with careful heat-treating and post-processing, also contributes to a greatly improved fatigue life. QA1 ensures these springs can be compressed to coil-bind without changing their rate or free height.

For a straight and consistent operation, both ends of the spring are ground flat. The springs are also clearly marked with their free length and spring rate for easy identification. QA1 proudly manufactures these springs in the USA and backs them with a lifetime guarantee, ensuring they remain within 2% of their original free height and rate under normal operating conditions. The silver powder coat finish not only looks good but also adds durability.
