Coil Over Spring 2.5in ID 16in Tall UHT Barrel

The HYPERCO Coil Over Spring 2.5in ID 16in Tall UHT Barrel is a precision coil-over suspension spring engineered for high-performance off-road vehicles, race applications, and custom suspension builds. This single spring delivers a firm 125 lb/in spring rate in a compact 16-inch vertical package, making it ideal for builders who need controlled ride height without sacrificing load capacity. The Ultra High Temperature (UHT) barrel design maximizes structural integrity under extreme compression and thermal cycling, while the blue powder-coat finish provides corrosion protection and a professional appearance in engine bays and suspension installations.

The 2.5-inch inner diameter accommodates standard coil-over shock shafts, and the 16-inch length fits mid-travel and long-travel suspension geometries common in rock crawling, desert racing, and lifted truck applications. The 125 lb/in rate provides moderate support suitable for vehicles in the 3,000–5,000 lb range, or heavier vehicles running dual springs per corner. The UHT construction resists stress relaxation during sustained heat exposure—a critical factor in rally and off-road use where repeated compression cycles and friction-generated thermal loads degrade standard springs over time. Weighing 5.62 pounds, this spring integrates into existing coil-over assemblies without requiring major suspension redesign.

This spring suits builders and enthusiasts upgrading independent suspension systems on vehicles ranging from vintage hot rods and classic trucks to modern off-road platforms. It pairs seamlessly with coil-over kits from manufacturers specifying 2.5-inch ID springs and serves as a direct replacement for worn or mismatched springs in multi-stage suspension builds. The straightforward coil geometry allows easy installation with basic suspension tools and is compatible with ride-height adjustment collars and locking rings.

HYPERCO has established itself as a supplier of performance suspension springs and bars to the racing and custom fabrication community. The coil-over spring market includes budget imports, mid-range OEM replacements, and premium race-spec options; HYPERCO positions itself in the performance tier, emphasizing material quality and thermal consistency. Individual springs are sold singly, allowing staged upgrades or replacement of damaged components without full suspension replacement.
