These coils are designed for the unique needs of Circle Track racing, providing more clearance for the standard circle-track racing shock absorbers. They are available in 14", 12", 10", 9", 8", 7", 6", and 4" lengths, and have rates from 100 to 900 pounds-per-inch. The barrel shape springs works effortlessly with the standard 2.5" perches for the spring whilst retaining the benefits of a larger diameter spring, with more shock body clearance and travel. The continuous taper that springs the XT Barrel to a maximum 3.0" ID enables the Eibach engineers increase the spring coil pitch beyond any of their previous designs, this technological design advancement produces a lighter spring, with an increased useable travel.

Made from the finest chrome silicon steel and renowned CNC coilers to produce extremely precise springs with exceptional durability and repeatability. The springs are individually rated and tested, made in the United States and they come covered by a million mile warranty.
