Xray Progressive Springs - Soft-Medium - 2 Stripes (2) 358276

New SOFT-MEDIUM progressive springs are soft at the beginning of the compression but become harder as the spring is compressed more in the middle, with highest hardness at the end. Marked with TWO stripes for easy identification. Set of 2. Fit both front and rear. Fits XB808 and XB9. 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 the higher corner speed is achieved. Available as a pair of springs – to fit both front and 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 recorded, and 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.
