I have been looking around for a heavy duty flex plate. I have found a SFI flex plate and was wondering if anyone has had any experience with them or know anything about them . The only thing I was able to find out was they are .035 thicker and the welds are longer. `

 

I have the suncoast flexplate in mine. It is probably overkill for the power I am putting down, but that's alright.

 

This company sell alot of parts for the dodge transmission parts. Good folks.I have a spare 2nd gen flexplate if u need one..

I was stranded on the road when my flex plate decided to gut itself. When it was repaired they said they put a second gen flex plate back in the truck. Do you think it will be alright. I only use this truck to tow. No racing or sled pulling.

 

even the stock 2nd gens are much stronger... sounds like a nice shop

 

As far as obtaining a service/replacement flexplate for our 1st gens, the original flexplate as came with our trucks has been superseded with the 2nd gen flexplates. Meaning you can only get the 2nd gen unit.

 

I have the same flex plate that bigjohn92 posted. It has been in the truck for approx 4years of hard driving & drag racing. When i bought it. It was only a 125$ came with paper work stating sfi approved It has worked good for me. But I did have to make a spacer to get clearance for torque converter to front pump.

 

I may put a flex plate in mine, I was wandering about the spacer you mention.
Will I need to buy a spacer?

 

yes if you don't have enough clearance between torque converter & the front pump

 

I put a 94 flex plate in mine and it is exactly the same thickness as my 93 was, down to the .001.

i think the 2nd gen beeing thicker is a mith or somewhere after 94 they went to a thicker one.

Dar

 

It's not an issue of thickness. The newer flexplates are shotpeened to strengthen them.

 

Thanks all for the input.

 

Does a 6.7 flex plate fit? and is it stronger than the 2nd gen since it doesn't have the cut outs?
