I'm going to be installing a FLT level 4 with a ss4000 in a couple of weeks, question is which flexplate should I go with or which one yall recommend or use?

 

Any flexplate made for the 4L60E thats SFI approved. Check out TCI

 

Hughes 4004x

 

^^What he said. I have the Hughes flexplate and it was reasonably priced for being SFI (around $150). I would be careful with going to TCI. Some guys have no issues with theirs, other guys do. When I was trying to pick a flexplate, I talked to my trans builder and he mentioned that he has seen TCI flexplates have too much runout when put on a machine and tested, which makes him uncomfortable with using them. Not trying to bash TCI, but I would be careful there. Let us know what you pick and how it works!

Do u like yours, any problems with it yet? I'm leaning towards t Hughes flexplate.

 

I like it a lot. No problems yet, but I only have about 1,000 miles on it. It fits just like stock (dished style), and it's SFI. The TCI's are flat, unlike the stocker, but this one is shaped just like the stock flexplate and it lined up right with the crankshaft with no problems. Here's the link to my review of it, along with some pics: https://ls1tech.com/forums/automatic...te-review.html
Hope this helps.
