LOCK-UP TORQUE CONVERTER

LS1 2800 +/- Stall converter for LS1 with aftermarket Cam and headers.

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.
