F3/OT-2 Clutch Disc, 7.25", 7/8x20 Spline, FF/SV

Brand: Tilton Engineering

This sintered metallic clutch disc fits the Tilton OT-II, AP F3, and Quarter Master 7 1/4" racing clutches. The 7/8" x 20 spline is normally used on Super Vee and Formula Ford 1600 applications, but cars converted from FC to FF (such as Swift and Van Diemen) may still use the 1" x 23 spline from the 2.0L engine. The extended "F-Type" hub (0.55" long overall) projects through the center of the clutch disc by 0.16". This provides more spline area for higher torque capability than the basic "A-Type" hub. Sold individually.

Tilton's minimum recommended clutch disc thickness is 0.074" in single-disc clutches or 0.089" on dual disc clutches. New clutch discs measure 0.104" thick.

Note: Not for use with stock Ford clutch, or on street-driven applications.
