Conv Front Spring 5.5in x 9.5in x 850#

The Conv Front Spring 5.5in x 9.5in x 850# from AFCO Racing Products is a professional-grade coil spring engineered for high-performance suspension tuning on road-race and track-focused vehicles. This conventional spring is designed for drivers and shops seeking precise spring rate control to dial in front-end geometry, load transfer, and anti-squat characteristics during acceleration and cornering. AFCO's racing heritage ensures this spring meets the demands of serious enthusiasts who refuse compromise on suspension dynamics.

With an 850-pound spring rate, this conventional coil delivers linear force characteristics ideal for vehicles running adjustable dampers and precision front-end setups where consistent spring behavior is critical. The 5.5-inch compressed length and 9.5-inch free length dimensions make it compatible with modern double-adjustable coilover systems and custom suspension builds requiring compact packaging without sacrificing travel range. AFCO manufactures these springs using high-quality steel with precision coil winding to maintain rate accuracy across the stroke, eliminating dead-band inconsistency that plagues budget aftermarket options and ensuring predictable brake balance and turn-in response lap after lap.

This spring suits drivers upgrading independent front suspensions on sports cars, autocross platforms, and road-racing builds where fine-tuning spring rate is essential to match driver preference and track conditions. At 9.35 pounds, the Conv Front Spring integrates seamlessly into lightweight suspension assemblies without adding unnecessary unsprung mass. Installation requires removal of existing springs and proper alignment of the new spring in the perch—pairing with compatible AFCO dampers and bump stops ensures optimal performance and prevents coil bind during maximum compression events on rough surfaces or under hard braking.
