9HT300 High Travel Coil Spring, 9in., 2-1/2in. ID, 300lbs/in.

QA1's 2.5" Diameter (I.D.) High Travel Coil Springs are designed for those who demand reliable performance from their suspension. These springs offer a balanced combination of maximum travel, consistent performance, and long-term durability, whether you're on the track or driving on the street.

HIGH TRAVEL DESIGN

What is a high travel spring? A high travel spring is engineered to maximize the suspension's movement range without compromising durability or performance. By designing the coil with a smaller diameter high-tensile, chrome silicon alloy wire and fewer coils, these springs compress further before reaching a solid state. This allows you to take full advantage of your available suspension travel, without the risk of bottoming out.

LINEAR SPRING RATE

At QA1, we prioritize consistency and predictability in our suspension systems, which is why our high travel springs feature a linear rate design. This means the spring rate stays the same throughout the entire stroke, giving drivers the confidence they need in various driving conditions. While progressive rate springs may offer a softer initial compression, they can introduce unpredictability as they stiffen during compression.

LIGHTWEIGHT

Our 2.5" diameter coil springs are made from high-tensile chrome silicone alloy wire, keeping them lightweight without sacrificing strength. They're tough enough to handle the demands of racing while still being a great fit for street use.
