QA1 3-1/2in ID Tapered High Travel Spring - 10in Length x 500lbs/in - Silver Powder Coated

The QA1 10HTSF500 is a high travel coil-over spring designed for optimized suspension performance. Made in the USA from high-tensile chrome silicon alloy spring wire, this spring features fewer coils and a smaller wire diameter for reduced weight and increased travel. It has a 3.5-inch upper inner diameter, a 2.5-inch lower inner diameter, and a length of 10 inches with a spring rate of 500 lb/in.

This spring is finished with a silver powder coat and has squared ends that are ground for straight, consistent operation. QA1 guarantees these springs for life to remain within 2% of their original free height and rate under normal conditions.
