The McLeod Mag Force aluminum twin-disc clutch kit is a direct-fit assembly for GM LS applications. It specifies a 1-1/8 inch x 26-spline input and is built to interface with a 6-bolt crank and a 168-tooth flywheel. This kit supplies the correct spline and crank mounting configuration for LS-powered replacements or drivetrain upgrades that require those exact fitments.
