That means they’re lighter for less unsprung weight, plus they react faster and serve up improved travel for optimized suspension performance. Each spring is heat treated and ground at both ends for consistent and accurate operation. They’re guaranteed for life by QA1 to remain within 2% of their original free height and rate under normal operating conditions. Finished with a silver powdercoat; for black, add B to the end of the part number.
