Balance Weight Information

It is very important when replacing Chrysler torque converters that the correct balance weight be used on your new converters. Chrysler engines with cast crankshafts require balance weights on the torque converter to bring the engine assembly into proper balance. Up until 1977, the factory converter came with two rectangular weights located on each side of the drain plug. There are three types of rectangular weights: A, B & C. In 1977, Chrysler changed to a single butterfly weight. These weights corresponded to the 'B' and 'C' weights. Please refer to the identification chart for weight type.

Rectangular A: .158" thick B: .250" thick C:.380" thick   Butterfly   B: 1.157" wide C: 2.545" wide   Square       S: .300"T/.219"L/.200"W

TCI maintains an inventory of our most popular street performance converters with the various balance weights already attached. If you prefer to order with balance weight, please see the chart below for counterbalanced Chrysler converters.

• 1992 & later 5.9L engines (360) use a square, unbalanced weight (referred to as an 'S' weight by TCI). The earlier butterfly weight will not fit the flexplate.
• 1996 & later converters have a 90° style bolt pattern and the counter balance is in the flexplate.
• 1993 & later A500 converters have flats on the hub.
