What are the benefits of adding a aftermarket flexplate when doing a highperformance convertor swap?

The late years have been showing flexplate cracking.
The earlier flexplate is sturdier. On a '98 I'd call it a
"don't bother" unless you are spinning higher and
putting out well more torque than stock?

I had my stock Flex Plate crack and split apart approximately 1.5 years after I installed a 3000 Stall 2.5 STR Torque Converter. I replaced it with the TCI Heavy Duty Flex Plate.

I've done many more mods since then and I have not had any other problems.

It doesn't seem like it's been to much of a problem with the other members or at least they have not posted that much on the subject.

I wouldn't replace it unless you are having problems.

I have a TCI flexplate on my TH400. Do I recommend you upgrading? Why not. It's not that expensive, and it's stronger and lighter. One of those "not neccessary" parts, yet not a bad idea either. I've heard the 98 flexplates are damn reliable even with gobs of power. I had an M6 and had to go with an aftermarket flexplate anyway. Still feel's good to know I have it.

One less thing to worry about. Only a couple hundred bucks, and it's SFI rated. Safety is always a good idea.

I replaced my stock flexplate on my 01 Z28, when I had my Y3000 2.0 STR TC installed. They had to remove 3 of the 6 bolts from the flexplate anyway to remove the TC, so I figured while they were in there, remove the remaining 3 and swap out the flexplate.

I replaced mine with the TCI SF-29 flexplate. The transmission shop told me the TCI unit was very heavy duty and well made, and my entire car could blow up and the flexplate would still be intact.

Go with a TCI , its worth it for the peace of mind to me.
