Coilover Spring 16in x 3.5in x 160lb

The SWIFT SPRINGS Coilover Spring 16in x 3.5in x 160lb is engineered for builders and enthusiasts who demand precision suspension tuning on street, track, or competition vehicles. This standalone coilover spring serves as a direct replacement or upgrade component in custom suspension builds, allowing you to dial in ride height, spring rate, and handling characteristics without committing to a complete coilover assembly. Whether you're fine-tuning an existing setup or constructing a ground-up suspension system, this 160-pound-rate spring delivers the consistency and durability that professional fabricators and serious home mechanics rely on.

At 16 inches in length with a 3.5-inch outer diameter, this spring is manufactured to SWIFT's exacting standards, offering a linear 160 lb/in spring rate that provides predictable load behavior under compression and rebound cycles. The compact 5.5-inch packaging footprint and 6.72-pound weight make it suitable for a wide range of vehicle platforms and mounting configurations. SWIFT's manufacturing process ensures consistent wire diameter, pitch spacing, and pre-load characteristics, eliminating the inconsistencies found in lower-tier alternatives and guaranteeing that your suspension geometry and handling remain stable across repeated track sessions or daily driving conditions.

This spring is ideal for engineers, suspension technicians, and builders who are constructing or refreshing independent or double-wishbone setups where spring rate and ride height demand customization. The 160lb rate suits mid-weight vehicles and street-performance applications where moderate stiffness prevents excessive body roll while maintaining driver feedback and comfort. Installation requires proper suspension geometry knowledge and tools; confirm camber and caster specifications after installation to ensure optimal tire wear and handling. Pair with compatible dampers and bump stops to realize full suspension potential and achieve the responsive, composed handling characteristics your vehicle deserves.
