Ultimate high-performance racing springs give you additional precision tuning options for your XRAY model racing car! Developed through extensive testing and racing experience, these racing springs were designed and precision-crafted to have a more progressive rate than standard XRAY racing springs. As the car enters the corner the spring is softer which generates more grip, but as soon the car inclines the springs get stiffer and a higher cornering speed is achievable. Available as a pair of springs – to fit the REAR – the springs are individually measured, controlled, inspected, and matched to provide identical damping characteristics. During the selection process, each spring is compressed in several fine increments and the values are recorded. Then each spring is matched with another spring of identical characteristics. XRAY goes the extra mile to ensure perfect spring matches, giving your car the predictability and consistency that you need to help you lead the pack. #358279 XRAY Long Progressive Springs - Soft-Medium -2 stripes (2) #358280 XRAY Long Progressive Springs - Medium - 3 stripes (2)
