Rear progressive springs specifically designed for use with big bore shocks. Set of 2.
The main advantage of progressive springs is that as the car initially enters the corner, the springs work like soft springs to provide maximum traction. When the chassis begins to roll in the middle of the corner, the spring rate progressively increases until the springs work like a hard springs which allows the car to maintain maximum cornering speed.
Like all the other XRAY springs, these springs are manually measured, selected, and matched into pairs to guarantee precisely equal length and damping characteristics.
