Vigilante 10.5" 3-Disk Lock-up Torque Converter 4L70E Corvette, Camaro

The introduction of lock-up torque converters from the OEM manufacturers in 1979 created a challenge for the high performance torque converter industry to develop, design and manufacture this type of torque converters. Benefits of the lock-up torque are less heat in the transmission and better fuel efficiency. Precision Industries designed the first 9.5 & 10.5-inch lock-up torque converter in 1992. Precision Industries starts the production of these torque converters with a 98 pound piece of billet steel that we machine in our CNC equipment ending up with a one piece front cover weighing 12 pounds depending on what converter series we are building. The billet front cover is one of many reasons that enable Precision Industries to produce a superior product over many of our competitors that try to imitate and copy our product designs We prefer machining our billet front covers over purchasing forged steel covers due to balancing, excessive weight and density problems that can arise from forgings. Benefits of our cover include increased clutch surface area by as much as 5 times over OEM specifications. The increase in clutch surface area along with the unique clutch lining we use ensures that no matter what the application you can retain the lock-up feature for efficiency without durability issues. Give your automatic LSx better launches and 60 foot times with a higher stall speed converter. The Vigilante is the top of the line converter from Precision Industries and is offered in a wide range of stall speeds. The converter is unique in that it offers a one piece billet mounting cover with no welded brackets, thereby reducing rotating mass and eliminating wobble for less run-out. The converter also features a high quality 4130 alloy machined turbine hub which prevents premature wear, fully enclosed thrust bearings which hold the oil at stall for better lubrication, and a fully furnace brazed impeller and turbine for better strength and efficiency. (We have experienced 0.40 second reductions in 1/4 times with this converter.) 4L70E Transmission for use with LS2 engine.
