Tilton 5 1/2" (140mm) cerametallic rally clutches are available as either single or twin plate designs and to fit step type flywheels.
Cerametallic or rally clutches utilise a driven plate which is thicker (7.1mm) in comparison to the sintered driven plate clutches. These paddle type driven plates which although a little heavier are smoother engaging than the thinner sintered plates and their greater mass gives them a little more heat capacity. The clutches benefit from Tilton's longer finger diaphragm design which allows them to be used with a 38mm contact release bearing. This reduces the pedal effort required to release and improves the modulation to facilitate better and more consistant starts. The one pieces aluminium clutch basket is of an open "lug drive" design which allows the clutch to run cooler and cleaner, the drive is transmitted to the cover via forged steel thrust buttons fitted in the legs, a more reliable and durable method than the thin stainless wear clips favoured by other manufacturers. These units are quite simply the best of their type available! Driven plates should be ordered seperately and are available in a huge range of spline and hub options. The clutch selection notes below should help you to choose the most appropriate version, but if you would like to discuss your specific application then please contact us.
