Conv Front Spring 5.5in9.5in x 1000#

The AFCO Racing Products Conventional Front Spring 5.5in x 9.5in x 1000# (model 21000-1B) is a high-rate coil spring engineered for performance vehicles requiring precise suspension tuning. Built by AFCO, a manufacturer trusted for racing suspension components, this 1000 lb/in spring rate unit delivers the front-end support needed in applications ranging from drag racing to road course setups where aggressive geometry and load transfer demand stiff spring rates.

This conventional spring measures 5.5 inches in outer diameter and 9.5 inches in length, fitting within standard suspension packages designed for mid-to-heavy-duty applications. The 1000 pound-per-inch spring rate indicates minimal deflection under load—ideal for vehicles that require minimal body roll and quick weight transfer during cornering or acceleration. Steel construction with black powder-coat finish provides corrosion resistance in both salt air and harsh shop environments. Weighing 10.6 pounds, it integrates into existing double-A-arm and coil-over setups where front spring replacement is necessary.

Buyers seeking AFCO Racing front coil springs for sale will find this model suitable for circle track racing, bracket racing, and street performance vehicles where stiffer spring rates reduce squat and dive while maintaining drivability. The 1000# rate balances response with street-manners tolerability, making it a popular choice over heavier 1200# or 1500# rates for drivers who want performance without sacrificing ride quality on varied pavement. Proper installation requires confirming OD, length, and rate compatibility with your existing suspension geometry and damper package before purchase.
