ABOUT THE TORQUE CONVERTERS

These converters are far superior to any other that you have tried or even seen. Each torque converter is built to the specs of your car. By doing this we can achieve the specific stall that you are looking for. You are not just buying a production unit. We custom build each converter for your car and for the way you drive. Our torque converters are designed to take any abuse that you can throw at them. We would like to introduce you to the most advanced torque converter in the industry.

1) We start with a 4130 Chrome-molly hardened steel hub, with large oil journals machined in to the bearing surface to increase oil flow to the bearing and throughout the entire converter.

2) All impeller fins are furnace brazed and hand TIG welded, to increase the durability of fins.

3) Two Heavy Duty Torrington bearings are placed on either side of the stator assembly.

4) The stator is then modified by adding additional lube orifice for additional cooling.

5) Inside we use a new Heavy Duty race and Heavy Duty springs and rollers are installed as well.

6) All turbine fins are precision wielded to the turbine to increase durability and strength.

7) Then 4130 chrome-molly hardened steel splines are wielded in place. These splines also have journals machined into the bearing surface to provide better lubrication to the bearing.

8) A new Hi Temp o-ring and washer are installed to ensure proper seal for lockup apply and holding.

9) The piston and damper assembly used are Heavy Duty and only the best (high temp carbon composite) lining is used. LOCKUP UNITS ONLY!

10) Finally for the cover, a laser cut re-enforcing plate is bolted and welded into place to reinforce the converter housing and provide the proper bolt pattern.

12 INCH CONVERTERS 700R4,4L60E, 4L65E and 200R

THE PLOW:

Stall in the 1200 to 1400 range. These are low stall heavy duty converters for those applications where lower stall speeds and durability are a must. They feature brazed fins, heavy duty sprags, and high temp superior-hold carbon composite converter clutch lining. These are available in 27 spline for the early, 1980 to 1984 700R4, and for all years 2004R. They are also available in late, 30 spline for the 1985 and newer 700R4, and for 4L60E up to 1998. Not available for LS1 1998 UP.

THE DAILY:

These stall in the 1800 to 2000 range. They are an excellent everyday street driver converter. They have that little extra stall over the average stock converter to add responsiveness without diminishing drivability. Fuel efficiency around town with these is virtually unchanged from the OEM converter. These converters also feature the high temp carbon composite lockup clutch, brazed fins and heavy duty sprag. These are available for the LT-1 engine, for the early 2004R, 700R4, and the late 700R4 and 4L60E transmissions. Not available for the LS1 1998 UP.

THE DRIVER:

Stall for these units is in the 2300 to 2500 range. These converters are in the higher stall range necessary for true street performance. They are not as fuel friendly as the Daily, but are a reasonable compromise, delivering excellent torque multiplication for great additional launch while still not generating the excessive heat associated with higher stall converters. They are an excellent converter for a moderate street “cammed” car, when the driver doesn’t mind a little compromise in efficiency in exchange for the added low end torque. This unit also features heavy duty sprag, brazed fins and high carbon lockup clutch. As with the other units, these are available for the LT-1 engine, for the early 2004R, 700R4, and the late 700R4 and 4L60E transmissions Not available for LS1 1998 UP.
