Eibach’s new XT Barrel coil springs are designed for the special needs of Circle Track racing, and are configured to provide additional clearance for standard 2.5-inch circle-track racing shocks.

Available in 4", 6", 7", 8", 9", 10”, 12” and 14” lengths with rates from 100 to 900 pounds-per-inch, their distinctive XT Barrel shape works seamlessly with standard 2.5-inch spring perches, allowing easy access to the lower ball joint while retaining the benefits of a larger diameter spring-with more travel and more shock body clearance. The continuous taper of Eibach’s XT Barrel springs to a maximum 3.0” ID allows our engineers to increase the spring-coil pitch beyond any previous designs, yielding a lighter spring, and increased usable travel.

Eibach’s legendary quality and proprietary high-tensile, chrome-silicon spring wire ensure that your XT Barrel springs will measure and perform the same, year after year.
