Spring 16in Coil-Over 3.0in ID

The EIBACH Spring 16in Coil-Over 3.0in ID is a precision-engineered coil spring designed for high-performance suspension systems, particularly in motorsport, off-road, and custom vehicle applications. With a 100 lb/in spring rate and 16-inch length, this coil-over spring delivers the controlled stiffness required for tuned suspension geometry and improved handling dynamics. The 3-inch inner diameter accommodates standard damper shafts, making it compatible with most coil-over shock assemblies used in competition and street performance builds.

The 100 lb/in spring rate strikes a balance between responsive cornering and ride compliance for vehicles tuned for both track days and spirited street driving. The high-strength steel construction with silver powder-coat finish resists corrosion while providing durability under repeated compression cycles. The 16-inch length suits mid-range ride heights and suits setups where vertical space is constrained. This specification is common in half-ton suspension upgrades, classic car restorations, and dedicated track vehicles seeking predictable load control.

Buyers specify EIBACH coil springs for their consistent load testing and repeatability across production batches. The 16-inch coil-over spring is favored by suspension tuners who prioritize consistency and long-term reliability over cost-cutting alternatives. Whether upgrading an existing coil-over system, replacing a worn spring, or building a custom suspension from components, the EIBACH 1600.300.0100S delivers the performance foundation serious builders expect.
