Conv Front Spring 5.5in x 9.5in x 600#

The Conv Front Spring 5.5in x 9.5in x 600# from AFCO Racing Products is a purpose-built coil spring engineered for high-performance automotive suspension systems. This spring is designed for racers, hot rodders, and serious enthusiasts who demand precise load control and consistent geometry during aggressive driving or competition. Whether you're building a street-legal performance car, a drag strip competitor, or a road course vehicle, this spring delivers the tuning flexibility that separates OEM suspensions from truly dialed-in chassis setups.

The 600-pound rate specification indicates the spring's resistance to compression—requiring 600 pounds of force to compress it one inch. The spring's overall length of 9.5 inches is critical for compatibility with your frame, suspension arms, and shock tower geometry. AFCO's design features a coil-over-compatible profile that accommodates damper packages while maintaining progressive load characteristics throughout the suspension travel.

This spring excels in custom coil-over systems and independent front suspensions, providing the necessary stiffness to control body roll and dive without causing excessive harshness or ride height loss on uneven surfaces. The 9.8-pound weight reflects quality high-carbon steel construction, heat-treated and stress-relieved for durability under repeated load cycles. This makes it an ideal choice for front-end applications requiring moderate spring rates.
