The AFCO Racing Products Conventional Front Spring 5.5in x 9.5in x 1200# (part number 21200-1B) is a high-rate coil spring engineered for racing and performance suspension applications. This 1200 lb/in spring rate component delivers the consistent load support and responsive handling characteristics demanded by competitive drivers and suspension builders who require precision spring performance under extreme driving conditions.
With a 5.5-inch outer diameter and 9.5-inch length, this conventional-style spring integrates into front-end geometries where stiff spring rates are necessary to maintain chassis control and minimize unwanted body roll during acceleration and cornering. The 1200 lb/in rate positions this component in the performance spectrum suitable for track-focused builds, autocross platforms, and high-demand off-road recovery systems. Steel construction with black powder-coat finish provides corrosion resistance for extended storage and outdoor use. At 11.45 pounds, the spring's mass is typical for this load rating and spring geometry.
This spring serves builders, race teams, and suspension specialists who are replacing worn springs or tuning existing suspensions for higher spring rates. AFCO Racing Products designs springs for competition duty, making this component appropriate for serious enthusiasts who understand spring selection, load requirements, and how rate changes affect ride quality and handling balance. Verification of fitment to your specific application and vehicle platform is essential before purchase.
Spring rate selection is critical in suspension tuning. A 1200 lb/in spring resists compression more aggressively than lower-rate options, resulting in reduced suspension travel and increased load support—desirable for minimizing dips under hard braking and maintaining consistent ride height during competitive driving. However, stiffer springs also transmit more road harshness to the chassis and require complementary damping and geometry adjustments to achieve optimal balance.
