Coil Over Spring 2.5in ID 12in Tall UHT Barrel

The Coil Over Spring 2.5in ID 12in Tall UHT Barrel by HYPERCO is a premium suspension spring engineered for serious enthusiasts and professional mechanics building high-performance suspension systems. This coil-over spring excels in custom chassis builds, off-road platforms, and street performance applications where precision spring rates and compact packaging are non-negotiable. Whether you're designing a custom lowered street car, building a competition off-road rig, or constructing a drift platform, this HYPERCO spring delivers the consistency and durability required for demanding automotive projects.

HYPERCO's Ultra-High Travel (UHT) barrel design maximizes compression travel while maintaining a compact footprint ideal for tight engine bays and custom suspension geometries. The 2.5-inch inner diameter accommodates standard coil-over shock bodies, while the 12-inch overall height provides substantial suspension range without requiring excessive frame modifications. UHT technology allows the spring to compress efficiently under load while resisting coil binding, making it suitable for both daily-driven lowered vehicles and race-prepped platforms that experience extreme vertical travel demands. The precision-wound construction ensures consistent spring rate across the entire compression stroke, eliminating unpredictable mid-stroke behavior that can compromise handling balance.

This spring pairs seamlessly with adjustable coil-over shock kits, fixed-mount suspension arms, and custom chassis fabrication work across sport compacts, domestic platforms, and import vehicles. Installers should verify spring seat diameter compatibility with specific shock body specifications and confirm ride height clearance targets before final assembly. The 5.35-pound weight is negligible in suspension system calculations, making this spring suitable for both street and motorsport applications requiring lightweight geometry tuning. Professional installation is recommended to ensure proper preload, compression, and center positioning for optimal suspension performance.
