Long Progressive Spring Set (2) (Medium Hard - 4 Stripe) by XRAY
This is a pack of two XRAY Long Progressive Rear Shock Springs. These 4 stripe springs are medium hard rate. Long 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.
These ultimate high-performance racing springs give you additional precision tuning options. 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.
