Looking to replace my flexplate on my 2014 Yukon XL Denali when I do my
transmission upgrade.
Can't really find a good HD/Performance Type - SFI - Flexplate
TCI gave me a part # 399757 but I think thats really a racing type and it is $320 ! Yikes

The summit racing one is affordable, but it has really bad reviews....

Anyone have experience here ??? that can help

No experience I guess here... the stock flexplates like to crack around the hub flange that mounts
to the crank. I found a new one that is sfi hd from PATC. $170.00.. So that's what I ordered.
wish i would have thought about it sooner, they could have shipped it with my Converter... oh well.
Shooting for end of next week to get trans out and beefed up !!

per circle d's recommendation i used a TCI- 799753 , has 3x10.75 and 3x11.066 iirc. the stock pattern is the 11.066.

I started with the circle d converter to the stock flex plate and then simply replaced the flexplate and used same circle d converter.

although it was $280 when i grabbed it so not much cheaper than the one you looked up

The converter I used is a GM cored PATC 6L80E 3 bolt - oem core
They sell it for $400 + ship + Core charge
I had it stalled to 1800 rpms
It has a .70 clutch vs stock .40 ( I don't know its inches , mm, thinckness ??)

I looked at lots of others as I was willing to spend $$ amount to make this thing live
with heavy towing and a SC'ed 6.2L. But, almost all of the billet type converters were
all built for racing/camaros/cts/ etc... And lowest anyone could get stall was 2200-2400.
I just didn't want that much stall for a heavy towing appl
