Coil-Over Spring 1.875in x 8in x 120# Black

The Coil-Over Spring 1.875in x 8in x 120# Black from AFCO Racing Products is a precision-engineered suspension component designed for serious track enthusiasts, road racers, and dedicated mechanics building high-performance or competition vehicles. This spring serves as the backbone of any coil-over suspension system, where spring rate directly controls how quickly the suspension compresses and extends under load. Whether you're tuning a dedicated race car, building a road course platform, or upgrading a street-performance machine, selecting the correct spring rate is non-negotiable for achieving predictable handling and consistent lap times.

AFCO's coil-over spring features a 120-pound spring rate, a mid-range specification that balances comfort on street applications with enough stiffness to control body roll during spirited driving. The 1.875-inch outer diameter and 8-inch free length are engineered to work within standard coil-over shock mounting heights, allowing integration with most aftermarket coil-over kits without modification. The black powder-coat finish resists corrosion and UV degradation, critical for longevity in both road and track environments. This spring's consistent rate ensures linear spring behavior throughout the suspension travel, eliminating the unpredictable mid-stroke stiffness variations found in lower-quality alternatives.

This coil-over spring is ideal for mechanics and enthusiasts upgrading independent front or rear suspensions on track-focused vehicles, street machines, or autocross competitors seeking more predictable weight transfer and reduced body squat. Verify your coil-over shock body diameter (typically 2.25 or 2.5 inches) before purchase to ensure proper seating. Installation requires disassembling the coil-over assembly, compressing the existing spring safely, and swapping in the new unit—a task well within reach of any equipped home mechanic or shop. Pairing this 120# spring with compatible shocks and anti-roll bars allows fine-tuning your platform's handling balance for maximum grip and driver confidence.
