Ksport SP21538 Replacement Coilover Spring 215mm 38kg/mm

The Ksport SP21538 is a direct-replacement coilover spring engineered exclusively for use with Ksport fully adjustable coilover systems. Built from high-tensile silicon chrome steel wire, this spring is cold-wound for strength and shot-peened for increased stress relief, ensuring long-lasting performance under demanding street and track conditions.

Key Features:

• Silicon chrome steel construction — high-tensile material provides superior fatigue resistance and durability
• 215mm spring length — designed to maintain correct suspension geometry and travel within compatible Ksport coilover assemblies
• 38kg/mm spring rate — delivers a firm, performance-oriented spring rate suited for aggressive street and track applications
• Exclusive Ksport fitment — engineered specifically for Ksport fully adjustable coilover systems; not a universal spring
• Sold individually (1 per pack) — allows targeted replacement of a single spring without purchasing a full set

Whether you're replacing a worn spring, tuning your suspension setup, or upgrading to a higher spring rate, the SP21538 is a factory-correct replacement that restores proper coilover function. Ksport offers multiple spring lengths and rates across their lineup, making it easy to fine-tune your suspension for your specific driving style and application.
