Heavy Duty SFI Flexplate

Dodge Plymouth Chrysler Mopar Engine to Mopar 727 or 904 Transmission

Mopar SFI approved Flexplate flywheel Mopar flexplate

This flexplate is a SFI approved, solid, extremely strong flexplate for use with any 6 bolt Mopar V8 crankshaft and a Mopar 727 or 904 Automatic transmission and torque converter. This plate is for 11", 10", 9" and 8" High Performance and racing and uses 7/16" bolt attaching holes for both the crankshaft and torque converter. If you have ever held a stock type Mopar flexplate, you know how weak they are. Do not risk damage to your expensive HP engine and transmission by using a weak stock type or other similar flexplate, step up to the JW Performance Solid SFI certified flexplate and know you have a much safer plate transferring your engine power to the transmission. This is a neutral balance flexplate.

JW Performance Automatic Transmission Rebuild Kit Contents

The main difference between the overhaul kit and the master kit is that the master kit includes the steels. Neither kit includes a transmission filter since many people already have spares, or prefer one type over another. The ultimate kit does include bushings and a transmission oil filter. If you want a filter it needs to be ordered in addition to a rebuild kit except, if you order an ultimate kit.

Short Rebuild Kit includes:

Gaskets and seals only

Overhaul Transmission Kit includes:

Alto or Raybestos red clutches, forward and direct clutches, front band, ring kit, gasket and seal kit

Master Overhaul Kit includes:

Alto or Raybestos red clutches, forward and direct clutches, steels, front band, ring kit, gasket and seal kit
