The Sonnax S019701K High Clutch Steel plate is a high-performance replacement part specifically constructed for GM Powerglide transmissions and designed to deliver robust durability in demanding conditions. Fabricated from premium Kolene® steel, this plate measures a substantial 0.070 inches in thickness and features 12 precision-machined outer teeth, providing enhanced wear resistance and improved engagement compared to slimmer OE alternatives.

Its thicker profile ensures consistent separation of friction discs under load, helping to prevent premature clutch dragging or burnout while maintaining stable line pressure. Ideal for performance builds or heavy-duty rebuilds, the S019701K steel plate installs seamlessly into standard clutch drums and reinforces the entire high clutch pack, delivering reliable performance, extended clutch life, and increased confidence across a wide range of Powerglide applications.
