Tilton Ceramic Dual Clutch Disc Set, 7.25", 1x23 Spline

Brand: Tilton Engineering

These "Cerametallic" clutch discs fit the Tilton OT-II 7 1/4" Dual Disc Rally Clutch. The 1" x 23 spline is normally used on Sports 2000 and FF2000 applications (note that many cars converted from FC to FF1600 such as Swift and Van Diemen often retain the 1" x 23 spline from the 2.0L engine instead of converting to the 7/8x20 FF1600 spline).

These discs have the standard "V-Type" hub (0.375" long overall), positioned on one side of the clutch disc. This provides sufficient clearance for back-to-back stacking in a dual-disc clutch. Sold in pairs (one set has 2 discs, enough for one dual-disc clutch).

The Cerametallic friction material was developed specifically for greater heat capacity and easier modulation (slipping) on loose rallye surfaces. This also makes it an ideal choice for racing series with standing starts, or endurance racing series with multiple pit stops. Tilton's minimum recommended clutch disc thickness is 0.268" on dual disc clutches. New clutch discs measure 0.283" thick.

Note: Not for use with Tilton OT-II "metallic" clutches (Tilton series 66-002 or 66-502).
