Tilton OT-2 Dual Clutch Disc Set, 7.25", 24mm x 23 Spline

Brand: Tilton Engineering

This is a set of 2 sintered metallic discs for the Tilton OT-II 2-Disc 7 1/4" Racing Clutch. The 24mm x 23 spline size has been used by Audi and Porsche (note that Tilton considers this a non-standard spline size and may not keep this size in stock).

Stacked "AB" hubs offer greater flywheel clearance than back-to-back "AA" hubs without sacrificing spline thickness. Both hubs are 0.375" thick at the splines, but the "B" hub is designed to almost touch the "A" hub. (The original "AA" pairing leaves a gap between the hubs.)

Tilton recommends replacement when the clutch disc friction material wears to 0.094". New discs measure 0.104" thick.

Note: Not for street use. These discs are not designed to work with any OEM clutch.
