Precision Stallion Torque Converter

Precision Industries 9 1/2-inch Stallion

C-4, C-6, AOD, AODE, E4OD The Stallion torque converter is available for most Ford automatic transmission equipped vehicles. The Stallion is available for lock-up and non lock-up applications. The standard performance gain reported is 2 tenths on 60 foot times and up to 3/4 of a second on overall elapsed times in the 1/4 mile. The torque multiplication on the 9 1/2-inch series is 2.53 to 1 compared to stock at 1.93 to 1. The torque multiplication of the converter will deliver an increase of up to 50 horsepower to the rear wheels. The front cover of the converter is machined out of billet steel to ensure durability and to allow us to increase the clutch surface area. The front cover of the 9 1/2-inch torque converters starts production as a 92 pound piece of billet steel and when the CNC machine makes the last cut it weighs about 12 to 14 pounds. Our unique billet cover along with other high performance internal parts allow us to produce torque converters that are custom built and designed for each individuals needs, wants and expectations. The 9 1/2-inch torque converters are tremendously efficient for daily drivers looking to enhance the performance of their cars with out sacrificing driveability. The "best of both worlds" as it is referred to, becomes a reality. The 9 1/2-inch series is capable of withstanding horsepower ranges from zero up to 1600 depending on the design and assembly. The average build time is 3 to 4 working days. The 9 1/2-inch non lock-up torque converter weight is between 24 to 26 pounds and the lock-up converter weight is between 32-36 pounds. The stall speed on our 9 1/2-inch torque converters are available from 2400-5800 rpm's depending on the application.

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. 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 beneficial for keeping the transmission at a cooler operating temperature.

Ford Powerstroke 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 Ford converters. This takes advantage of the torque the Powerstroke diesel makes at the low RPM range. The result is dramatically improved towing power.
