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. Requires specially modified flywheel. Discs sold separately.
This OT-III clutch uses the high-strength Gray diaphragm spring. The Gray spring gives this clutch a rated torque capacity of 750 lb-ft, but it also requires 850 pounds of force to release. Cable actuation systems and external slave cylinder release mechanisms will not work with the OT-III clutch. A hydraulic release bearing (38mm bearing contact diameter) is required.
Note: This "Pot Type" clutch is designed for use on a specially-modified flywheel. The friction surface must be flush with the clutch mounting surface. This is different than the traditional "Step Type" racing clutch which requires the friction surface to be higher.
