Sonnax 10" performance converter mounting ring kit GM-RK-14 provides torque converter builders the components for producing low-cost, high performance converters for the GM Powerglide, TH350 and TH400. Using this kit allows the use of the OE GM 245mm front cover.
When using in a Powerglide application the impeller hub must mount .070" taller. Either leave a .070" boss on the impeller to extend the height when using the impeller hub included in the kits or use a GM-90-300G impeller hub and cut it down to 3.695" length.
Designed from the ground up to outperform OE and other aftermarket components, Sonnax has you covered with a full line of performance converter kits for gas and diesel vehicles. Offering the widest variety of options in the aftermarket, these innovative kits deliver customized performance and value.
