Show original supplier description
The Circle D Specialties GM 245mm Pro Series 4L60 LS Torque Converter is a premium billet torque converter designed for enhanced performance in street/strip vehicles, including F-bodies, trucks, and GTOs. This converter features a 245mm (9 3/4 inch) diameter and offers a customizable stall speed range from 3200 to 4600 RPM, allowing for optimal performance tuning. The converter is further reinforced with an anti-ballon plate and utilizes Torrington-style bearings for smooth operation. For maximum strength and longevity, the fins and turbine hub are hand TIG welded, and the entire assembly is furnace brazed and hand-assembled to exacting tolerances. This torque converter is specifically compatible with 4L60E, 4L65E, and 4L70E transmissions. Please note that for 2005 Corvettes, it is recommended to call for specific fitment details, and for 97-04 Corvettes, the "4L60 LT" model should be referenced.
