4L60E / 4L65E 10" Triple Disk Lock-Up SuperStreet Master Torque Converter w/ Billet Cover

4L60E / 4L65E - 10" Triple Disk Lock-Up SuperStreet Master Torque Converter w/ Billet Cover

The Streetmaster® Torque Converter is designed to make the most of your everyday driving needs. It's commonly used to enhance bottom end torque characteristics without sacrificing cruise efficiency. This unit generally provides an 800 to 1000 RPM increase in stall speed when used with stock-type rear end ratios and mildly modified engines. We put the same technology into Super Streetmaster torque converters as all our championship winning parts.

We furnace braze the pump and turbine and install a new billet stator cap, springs and rollers in the sprag. A new hub, pilot, and mounting ring are installed and CNC-machined for perfect accuracy. ATI’s components are factory reinforced with your weekend cruiser’s performance in mind.
