Soon, I will have Relentless install or modify valve body, billet input shaft and a TC. I am a heavy hauler (13K plus, 5er) not a drag racer. So do I need a billet flex plate or will a heavy duty flex plate do the job? I have found a few heavy duty plates that claim to be 30% thicker.


Thanks for your response

 

I have heard good things about the Suncoast flexplates and heard issues with the ATS billet flexplate the did not flex enough causing billet input shafts to break. I would get the Suncoast.
