SFI Flexplate
Installed and works fine. No starter gear noise, I had been having Flexplate troubles as my engine is cammed, etc. Stock flexplates were breaking close to center twice. At the same time the flexplate was installed, I installed a bigger cam, ported heads, 4,200 converter. My flexplate troubles should be done with finally. Fast shipping, great value.

Works for me!
I've got a 5.3 mated to a 4l80E and it worked perfectly with this combo. I'm sure it'll last as long as I need it to. Looks like a quality piece.
