Description
Whether you’re dialing in suspension geometry for track performance or replacing worn springs that have lost their compliance, a properly-rated shock spring is non-negotiable for consistent handling and tire contact. The Factory Connection 300 lbs/in spring delivers the precision tolerances and fatigue resistance you need for reliable performance across multiple racing seasons, without the guesswork of inferior aftermarket alternatives.
This domestically-manufactured spring combines cold-wound CNC precision with shot-peening and heat-treating to handle the repetitive stress cycles that break lesser components. You get accurate spring rates, predictable suspension behavior, and a spring engineered to last.
