For customers with demanding GM 6L80/90 gas-powered applications that use a full-size torque converter, Sonnax has introduced an easy-to-build, cost-effective performance converter kit (#GM-RK-21). Employing a forged cover, forged piston and three woven carbon friction elements, builders now have a dampered 300mm multi-plate option that delivers significantly increased clutch capacity and durability. By re-using the OE damper with the Sonnax clutch plates (bonded with OE woven carbon friction material), this kit ensures optimal TCC apply and release characteristics, as well as slip rates that match OE continuous slip calibrations.
