wanting to know whats out there for stronger then stock flex plate for a 2009 sierra denali with the 6L80E transmission and 6.2L (L92) motor.


thanks

 

The 6L80E's use the same "Dished" Flexplates as 300mm 4L60E's, Several companies make SFI approved flexplates but might not have updated their application guide.....If the flexplate fits a 5.3L truck with a 4L60E, It will fit your truck! I would share some links but I'm new & don't know the rules about that.

 

Yea I've been trying to find one to buy for my Whipple build and my 6L80E and its really hard to track down one that says it fits the 6L80E trans. I even called ATI and they couldn't give me a solid answer. Any flexplate company recommendations.

I had one from Mezier I sold on here awhile back only because I swapped to a 4l80. Badass flexplate that would be plenty for anything on this site.
