Ultimate high-performance racing springs, which provide precision tuning for your XRAY model racing car! Developed from extensive testing and racing experience, these racing springs were designed and precision-crafted to have a unique spring characteristic. The XRAY spring sets were designed to give you an optimum range of choices to fine tune your car.

Each spring set contains four identically-matched springs, and are designed to work with the new XRAY shock absorbers. All four springs in a set are the same length, and all springs are colour-coded for easy identification.
