Coil Over Spring 2.5in ID 5in OD 16in Tall

The Coil Over Spring 2.5in ID 5in OD 16in Tall from HYPERCO represents the precision-engineered backbone of any serious suspension upgrade, whether you're building a track-focused race car, a street-performance daily driver, or a custom off-road platform. As a mechanic who's spent countless hours dialing in suspension geometry, I can tell you that spring rate consistency and load capacity are non-negotiable—this coil-over spring delivers both. HYPERCO springs are manufactured to exacting tolerances, making them the choice for builders who refuse compromise when it comes to ride quality, handling predictability, and long-term durability under extreme driving conditions.

Built with a 2.5-inch inner diameter and 5-inch outer diameter, this 16-inch-tall coil-over spring is engineered to work within coil-over suspension kits that demand precision fit and reliable performance across a wide range of spring rates. The specific dimensions allow for seamless integration into most modern coil-over platforms, while the compact yet robust design minimizes unsprung weight while maximizing structural rigidity. HYPERCO's manufacturing process ensures consistent wire diameter, proper preload characteristics, and uniform coil spacing—all critical factors that prevent bind-up, reduce noise, and maintain consistent spring rates over thousands of suspension cycles. At 6.1 pounds, this spring balances strength with lightweight design, making it ideal for both street and competition applications where every fraction of a pound matters.

This coil-over spring is perfect for enthusiasts building custom suspension systems, whether paired with adjustable dampers for daily-driven performance cars or integrated into dedicated track setups where precise ride height and load distribution are critical. The 2.5in ID / 5in OD configuration is compatible with most universal coil-over platforms and popular aftermarket suspension kits from brands that spec HYPERCO components. Installation requires proper spring compressor tools and knowledge of suspension geometry—many builders work with a suspension specialist to ensure correct spring rates are selected for their vehicle's weight and intended use. Whether you're lowering a sports car for improved cornering compliance or building a custom chassis, this HYPERCO spring delivers the quality and consistency that separates amateur builds from professional-grade results.
