Coilover Spring 3.0in ID 16in Tall 150lb

The Coilover Spring 3.0in ID 16in Tall 150lb from DRACO RACING is a precision-engineered suspension component designed for performance vehicles and race applications requiring independent spring rate control. Coil-over springs are essential for builders and enthusiasts seeking adjustable ride height, improved handling geometry, and customizable suspension tuning. This 16-inch tall spring with a 3-inch inner diameter accommodates most coil-over strut assemblies and allows drivers to dial in their exact suspension setup for track days, autocross, street performance, or off-road use.

Manufactured from high-tensile steel and finished with a durable purple powder coat, this coil-over spring delivers a 150 lb/in spring rate—a moderate rate suitable for balanced suspension tuning across a wide range of vehicle weights and driving conditions. The 3.0-inch inner diameter ensures compatibility with standard coil-over shock bodies, while the 16-inch length positions this spring in the mid-range for both lowered and stock-height applications. The purple powder coat not only provides corrosion resistance and extended service life but also makes identification and aesthetic customization straightforward during installation and future maintenance.

Performance enthusiasts, suspension shops, and race teams benefit most from this component when building or upgrading independent double-A-arm, MacPherson strut, or multi-link suspension systems. The 150 lb/in rate pairs well with vehicles in the 2,500–4,500 lb range and works effectively when stacked with other springs or combined with adjustable dampers for advanced tuning. Installation requires dismounting the coil-over assembly and compressing the old spring safely before installing the new DRACO RACING unit; proper spring compressor tools and suspension knowledge are recommended to ensure safety and correct geometry.
