Brand: Tilton Engineering
This bolt kit attaches Tilton OT-II dual-disc clutches to step-type flywheels with holes threaded in the flywheel. The six 5/16-24 UNF bolts have 1.59" under-head length and 1.06" grip length.
Not for flywheels with through holes. This bolt kit is for conventional step-type flywheels (friction surface 0.10" higher than clutch mounting surface), not for pot-type flywheels (friction surface flush with clutch mounting surface). All of the Tilton clutches we stock are the step-type.
