Brand: Tilton Engineering
This 5 1/2" clutch disc fits Tilton OT-III 5 1/2" Disc Clutches. The 7/8" x 20 spline pattern is common in FF1600, Formula Atlantic/F3, F3000, and Indy Lights.
The thin (C) hub is designed for multi-disc clutches such as the Tilton OT-III 5 1/2" Triple-Disc Clutch (Part No. TE 67-003HG). It should not be used in a single-disc clutch because of the limited strength of the splines. Sold individually.
Tilton's minimum recommended clutch disc thickness is 0.094" in triple-disc clutches. New clutch discs measure 0.104" thick.
Note: Not for street use. This disc is not designed to work with any OEM clutch.
