The Texas Speed Hemi SFI Chromoly Flexplate is an SFI 29.1 certified replacement flexplate for 5.7L and 6.1L Hemi engines in Chrysler, Dodge, Jeep and Ram vehicles with an automatic transmission. It is made from cold-rolled chromoly steel and is intended for Hemi owners who have added power or race their vehicle and want a certified plate in place of the stock stamping.
The plate is internally balanced and uses the 8-bolt Hemi crankshaft pattern with a 131 tooth ring gear. The forged one-piece steel ring gear is double welded to the plate, the chromoly plate is .035" thicker than the factory part and a gold irradiate finish keeps rust off the plate inside the bellhousing. It is a direct bolt-on part sold as a single flexplate. The converter bolt pattern is 8 x 12.00" to match the factory style Hemi torque converter.

FAQ
What engines does the Texas Speed Hemi SFI flexplate fit?
Texas Speed lists this flexplate for the 5.7L and 6.1L Hemi with an 8-bolt crankshaft flange, which covers the 2003 and newer Hemi engines in Chrysler, Dodge, Jeep and Ram vehicles with automatic transmissions.
What converter bolt pattern does the Hemi flexplate use?
The Texas Speed 5.7L/6.1L Hemi flexplate is drilled for an 8 x 12.00" torque converter bolt pattern, matching the factory style Hemi converter.
Is this Hemi flexplate SFI certified?
Yes. It is SFI 29.1 certified, the specification many sanctioning bodies require for automatic transmission vehicles running quicker than a set elapsed time at the drag strip.
How does this compare to the Texas Speed high inertia Hemi flexplate?
Both are SFI 29.1 chromoly 8-bolt 131 tooth internally balanced plates with the 8 x 12.00" converter pattern. The high inertia version (TSP-37010) adds a heavier design that Texas Speed states is intended to maximize valvetrain efficiency, and costs more.
What makes this stronger than the stock Hemi flexplate?
It is cold-rolled chromoly steel .035" thicker than the factory plate, with a forged one-piece steel ring gear that is double welded to the plate and a gold irradiate finish to prevent rust.
