FTI 9.5in 4L60E/4L65E/4L70E Billet Lock-Up Street Racer Series - LS - 3200 Stall

If you're looking to get more out of your LS-powered vehicle with a 4L60E, 4L65E, or 4L70E transmission, a performance torque converter can make a big difference. This FTI Performance Street Racer Series converter is built for those who want improved acceleration and a more aggressive feel for street driving and occasional track use. It's designed to work with LS engines and offers a 3200 RPM stall speed, meaning the engine can reach that RPM before the converter fully locks up and transfers power, giving you a strong launch off the line.

This converter features a 9.5-inch diameter billet cover, which is a strong and well-built piece that helps handle the increased power and torque. The internal components are furnace brazed and TIG welded for durability, ensuring it can withstand the demands of spirited driving. It also utilizes triple Torrington bearings, which help reduce friction and improve longevity compared to simpler bearing designs. This combination of robust construction and thoughtful engineering aims to provide reliable performance for a wide range of vehicles, including popular models like the Chevrolet Camaro, Pontiac Firebird, and GMC Sierra.

When installing a torque converter, it's crucial to ensure it's fully seated against the transmission pump before bolting the flexplate to it. This FTI converter is designed as a direct replacement for many GM vehicles from the late 90s through the late 2000s. Always refer to the manufacturer's installation instructions for proper seating and fluid fill procedures to ensure optimal performance and longevity.
