Xray XB8 medium-hard progressive springs
Xray have new optional progressive shock springs for the XB8 buggy available. The medium-hard springs are the stiffest progressive springs in Xray’s line-up and they are made for high-grip surfaces. The progressive design improves steering at corner entry as the springs become harder during compression. They come marked for easy identification and are available as medium length C=0.75-0.85 front and long C=0.65-0.70 rear variant.
