SFI certified LS 6 bolt to TH400/4L80e flexplate.
Disappointed with how often my customers were getting sold the wrong flexplate, I’ve decided to stock a high quality plate in-house. Made by FI New Power, SFI certified and guranteed to be the right part. This will allow you to bolt any TH400 with a normal 6.120 height converter and any 4L80e with a 6.800 height converter to any LS based gen 3 or 4 engine (except for the exceedingly rare early “long crank” 6.0L) will also fit LT engines with aftermarket 6 bolt cranks.
Converter bolt patterns are 3 sets of 3 on the following bolt circle diameters: 10.75”,11.083”, 11.5” which are the most common three GM BCD’s
If you need something for a different application, please contact me and I’ll see if FI New Power has them in stock.
shipping is generally around $20 across all CONUS
