Coilover Spring 16.000in Length 3.5in Diameter

The DRACO RACING Coilover Spring 16.000in Length 3.5in Diameter (MPN: DRA-C16.3.5.125) is a precision suspension component engineered for high-performance motorsport and off-road applications. With a 125 lb/in spring rate, this conventional coil spring delivers consistent damping characteristics essential for vehicles requiring tunable suspension geometry and improved handling dynamics during competitive driving or rugged terrain navigation.

This 16-inch coilover spring features a 3.5-inch inner diameter and is constructed from steel with a durable purple powder-coat finish that resists corrosion while maintaining aesthetic appeal in exposed suspension setups. The 125 lb/in rate represents a moderate spring constant—stiff enough to minimize body roll and maintain tire contact patch during lateral acceleration, yet compliant enough to absorb significant vertical articulation without excessive harshness. Each unit weighs 5.22 lbs and measures 4.9 x 4.8 x 17.1 inches, making it suitable for standalone replacement or as part of a complete coilover assembly on vehicles with comparable suspension packaging.

Coilover springs of this specification are commonly used in track-focused builds, rally platforms, and lifted off-road systems where suspension geometry tuning is critical. The 125 lb/in rate pairs well with vehicles in the 3,000–4,500 lb range, providing a balance between ride comfort on public roads and controlled body motion during aggressive cornering. Buyers should verify fitment compatibility with their vehicle's coilover kit before ordering, as spring rates must match the damper valving and ride-height requirements of the complete suspension system.
