    Best Flexplates on the market
  

*by L***B on Reviewed in the United States on November 8, 2018*

This is the 2nd flexplate I have bought from PRW, the 1st one was for our 409 Chevy and that saved our butts because there is not another company that sells them for the old '09. This one is perfect as well. Will buy and recommend PRW products as well. Very Happy with this purchase.

    Bolt it to the crank and go
  

*by M***. on Reviewed in the United States on January 7, 2019*

This was shipped very quick, bolted on my Chevrolet 454 ci. (gen 4 )and it worked great with my starter. Cad plate is nice, welds on the counter weight are looking good too. Ran true, no vibrations. I would buy again if I needed another one.
