QA1 2-1/2in ID High Travel Spring - 10in Length x 150lbs/in - Black Powder Coated

This is a QA1 2-1/2 inch inner diameter high travel spring, measuring 10 inches long with a 150 pound per inch spring rate. It's finished in a durable black powder coat. These springs are built to give your suspension the most travel possible while keeping unsprung weight down, which helps your wheels react faster to the road surface.

QA1 makes these springs from a special high-tensile chrome silicon alloy wire. This allows them to use fewer coils and a smaller wire diameter compared to standard springs. The result is a lighter spring with more space between the coils, giving you that increased travel. Being lighter also means less mass for your suspension to control, leading to better overall performance. They're made in the USA and are built to last, with a lifetime guarantee to stay within 2% of their original free height and rate under normal use.
