What makes this a 'high travel' spring?

This spring uses a specially designed chrome silicon alloy wire. This allows for fewer coils and a smaller wire diameter, resulting in a lighter spring with more distance between coils, which translates to increased suspension travel.

What does the 'pigtail' end refer to?

The 'pigtail' refers to the shape of one end of the spring, which is designed to interface with specific suspension components. This specific spring has a pigtail end and is ground flat on the other end for consistent operation.

What is the benefit of reduced unsprung weight?

Reducing unsprung weight, which is the weight of the suspension and wheels not supported by the springs, allows the suspension to react more quickly to road imperfections. This leads to improved tire contact and better overall handling.

Product Details

Starting with a 3-1/2 inch inner diameter and a 650 lb/in spring rate, this QA1 high travel pigtail spring is built for performance. It's constructed from chrome silicon alloy wire, which allows for fewer coils and a smaller diameter. This design means the spring is lighter, reducing unsprung weight for faster suspension response, and it offers increased travel because of the larger distance between the coils. The spring is also compressed to coil-bind without affecting its rate or free height, thanks to the material and careful heat-treating process.

This spring is 10 inches long and features a silver powder coat finish for durability. Both ends are ground flat for straight, consistent operation. QA1 proudly makes these springs in the USA, and they are lifetime guaranteed to remain within 2% of their original free height and rate under normal use. This spring fits a wide range of vehicles, including classic muscle cars like the 1967 Chevrolet Camaro, 1965 Buick Gran Sport, and 1968 Chevrolet Nova.
