GM 300mm Pro Series 6L80 Triple Disk Torque Converter

This is a great upgrade for 6L80/6L90 truck owners who are looking for a more durable converter along with a slightly increased stall speed. TCM tuning required!


This converter is a fantastic upgrade over the OE 6L80 Converters. A daily-driver friendly stall speed coupled with billet components makes this a no-brainer for your mild cam 6L80 build!
