Tilton 5.5" OT-3 Triple Disc Clutch, Gray Spring (No Discs)

This item qualifies for FREE Shipping in the continental United States!

Brand: Tilton Engineering

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 "Step Type" clutch is designed for use on a specially-modified flywheel. The friction surface must be 0.10" higher than the clutch mounting surface.
