LOCK-UP TORQUE CONVERTER

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 1/2-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.

Warranty and Other Information Precision Industries

9 1/2-inch torque converters are backed by a 2-year warranty. Included in our 2-year warranty is one free stall adjustment within the first two years from date of purchase. Precision Industries offers the free stall adjustment as a bonus to the customer realizing that most enthusiast usually continue to modify their vehicle as time and money allows. Due to the unique design and versatility of the 9 1/2-inch torque converter the need to purchase an additional torque converter in the future is practically eliminated. The adverage gain on the 9 1/2-inch torque converter series is 2 tenths on 60 foot and up top 3/4 of a second on overall elapsed times in the 1/4 mile. The adverage horsepower gain is up to 40-50 horsepower to the rear wheels due to the torque multipication and increased stall speed. Precision Industries torque converters are purple in color when shipped and depending on the transmission operating temperature may change color and/or the tint of the purple may change. The color changes are used to help us evaluate and eliminate any potential overheating problems the customer may be experiencing. The use of external transmission coolers are left to the customers preference but are not a requirement for using our torque converters. Note that when customers are installing non-lock up torque converters with higher stall speeds a transmission cooler would be benifical for keeping the transmission at a cooler operating temperature.

GM Allison 1000 Duramax Diesel Multi Disc Converters

Precision Industries 9 1/2" converters free up horsepower and torque! If that isn't enough, PI diesel converters are made at a lower stall speed than the factory GM converters. This takes advantage of the torque the Duramax diesel makes at the low RPM range. The result is dramatically improved towing power.Please note they will be a $200 core charge added after checkout which is refundable once Precision Industries gets a core back
