Notes
May not work with some 1999-2000 LQ4 6.0 LS engines, specifically ones that came with a 4L80E automatic as they require a flat flexplate due to the "tall" crank flange.

It appeared this would work well for my application, but the flexplate disc was not welded perfectly level, so the flexplate wobbled as it turned, beating itself up and the starter. Do not buy.Shrapnel from the gear teeth also tore up the rear main seal...

I installed this to proper torque specs and it wobbles and is unbalanced. Since everything is assembled in stuck with it until I change the TH350 transmission over to a 4L80e in the spring. Beware, have it balance checked before installing.
