These 7.8" organic drive plates from Helix feature a sprung centre design to provide protection from drive line shock, thus prolonging the life of the clutch and minimising the risk of failure. The springs are arranged radially around the centre of the hub which works in conjunction with the facing segments to provide a progressive engagement and greater degree of clutch control. The plates are made with only the best quality organic friction material available.Available is a wide range of spline sizes to suit most applications
