Xray XB9 long progressive springs
New from Xray come long progressive springs for the rear end of the XB9 and XB808 buggy. They are designed to reduce chassis roll mid-corner by becoming stiffer when the suspension compresses. Available as soft-medium and medium variant the springs are individually measured, controlled, inspected, and matched to provide identical damping characteristics and come marked for easy identification.
