For greater durability and more consistent performance from your GM Powerglide transmissions, TCI brings you these dual ring servo kits. The kits use two stock PTFE sealing rings in place of the original design, which uses only one. This doubles their sealing effectiveness and prevents the excessive leakage that could otherwise reduce band force. Perfect for drag race vehicles seeking positive trans-brake engagement when staging, these servo kits reduce vehicle rocking and increase stability in lower gears.
