Stock replacement

This is a standard, stock replacement flexplate at a very affordable cost. If you're in there, you can't justify not replacing it at this price. It fit a little more snug than I'm used to, but worked just fine after torquing the mount bolts alternately. No frills. Just a good solid replacement to add a piece of mind.

Most Liked Negative Review

1.0

Not impressed.

There were 3 large unevenly spaced gaps between the ring gear and the plate. I suspect the center plate was not completely round, and it definitely did not fit tight inside the ring gear. They had to bridge the gaps with the welds. 10 of the 12 welds looked like cold welds (not enough penetration, the plate wasn't even blued on the opposite side, like in the picture). The counter weight appeared to have cold welds also. It was made in India. I did not use this flexplate. I bought one from a auto parts chain store for a few dollars more, and the quality was OEM spec. Between the cheap price, and hassle to ship it back (live 25 miles from post) I decided to trade it to a guy who will probably use it on a demo derby car.
