Moose Offroad Hard Fork Springs - Parts (ref. 0405-1143)

Fork springs designed for off-road use (enduro and motocross), made from high-quality chrome-silicon wire. Each spring is cold wound and then subjected to a complete thermal cycle (heat treatment and tempering), shot peened, ground to pitch and ends, and then polished to reduce friction points. The spring rate is laser-engraved on the end, and the parts meet the DIN2095 grade 1 standard.
