Xray 368273 REAR SPRING-SET PROGRESSIVE C=0.35-0.45 - 2 STRIPES (2) (XB4)
The XB4 springs have been specifically designed to complement the big bore shocks.
The springs, like all the other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.
The main advantage and benefit of progressive springs is that as the car initially enters the corner they work like a softer spring to provide maximum traction. At the same time, when the chassis begins to roll, in the middle of the corner, the spring rate progressively increases until it works like a stiffer spring which allows the car to maintain maximum cornering speed.
