Tilton 5.5" OT-3 Series Clutches and Parts

The Tilton OT-III is a very high-quality open style 5 1/2" diameter racing clutch. The aluminum cover is much lighter and stiffer than the stamped steel cover used on many competitors' clutches. A 5 1/2" clutch significantly reduces rotational inertia over a 7 1/4" clutch, improving acceleration and reducing crankshaft stress during gearchanges. The drawback is that disc wear is more rapid than with a 7 1/4" clutch, so you should be prepared to replace discs more frequently. These racing clutches require a specially modified flywheel.

Clutch Assemblies include the cover and pressure plate. Clutch discs and bolts are sold separately. The replacement Clutch Covers do not include clutch discs, pressure plates, or bolts.

A hydraulic release bearing (38mm bearing contact diameter) is required with these clutches. The lightest (White) spring requires 480 pounds of force to release. Cables, linkages, and external slave cylinders will not work.
