Description

IMPORTANT NOTICE: This will not fit 1999-2000 6.0L applications with 0.400 in. extended crank flange and came with flat flexplate. This will not fit 1999-2000 4.8L applications that originally came with a manual transmission.

For serious performance, TCI machined SFI-approved flexplates are a "must have". These .140 in. thick flexplates are constructed of A514 Blanchard ground steel and are SFI 29.1 approved. TCI offers a complete line of Chrysler and Ford flexplates with GM and Ford bolt patterns for use with their adapter plate kits as well as neutral balanced flexplates with 168-tooth and 166-tooth starter rings for Chevy and Pontiac applications. Now you can speed down the track with the confidence of TCI machined SFI-approved flexplates.
