Price range: $102.45 through $137.35
Hyperco UHT Ultra High Travel Barrel Springs
Hyperco’s Ultra High Travel (UHT) barrel springs are built specifically for light-rate, high-travel coil-over applications in dirt and pavement racing. They are engineered for the soft-spring, big-bar setups those cars favour, and they hold their free length and installed height consistently as they cycle. The UHT design uses a more pronounced barrel-shaped “body bulge” than Hyperco’s standard OBD profile — that extra body diameter buys additional deflection, improves rate linearity, and makes the spring more resistant to bowing under load. All springs in this range are the 2.5″ I.D. B series.
Select your part number from the drop-down. Use the chart below to find free length, rate, rate type, deflection, load and coil dimensions for each SKU. Some part numbers are dual-rate springs, shown with two rate figures. All dimensions are given in inches and millimeters.
