TH400 Ultralight Chromoly Forward Drum W/ Shaft (EA34554HDA)

ULTRALIGHT CHROMOLY DRUM W/ SHAFT

• The Chromoly steel material provides overall reduced weight and low rotating mass - Weighs 3 lbs. less than an OE-style drum and is only 3-oz. heavier than an aluminum drum
• The front of the drum is ribbed and added with lightening holes
• The inner section diameter at the middle seal ring area is reduced for further weight savings
• The oversized 28-tooth shaft-to-drum spline is compatible with most aftermarket input shafts
• Compatible for use with rubber clutch separators for clean neutral setup applications - (2) sets of full-length clutch splines were added to back up clutch separators
• The lightening holes correspond to input speed sensor locations in aftermarket cases for a more accurate converter and shift data
