I think my 6.0 is from an 02. can I use the flexplate on it, or do I use mine from the 5.3?? I'm in a hurry, and confused. Thanks

 

Gotta swap it with one from your old motor.

 

Cool, thanks. I was worried it was a little more involved.

 

I've been considering going with a TCI flexplate when the time comes, I've heard that they're considerably stronger than the factory ones...any thoughts on this?

 

I recently put one in my Tahoe along with my built tranny. It is WAAAAY beefier than the oem one. Twice as thick and a beautiful finish even though nobody will see it. I have heard the 01-03 flexplates are weak and I didn't want to take any chances with a rebuilt trans and higher stall converter. Only issue I had was I needed longer torque converter bolts due to the thicker flexplate.

 

Is the TCI one quite a bit heavier than stock since its thicker or do they use different metal to keep the weight down?
Reason I ask is because I thought I remember people going to lighter flywheels and flexplates to keep the rotating mass down. Suppose to help the motor spin up quicker.

 

Didn't weigh them but I'd say the TCI was 30% heavier than the stock unit. And yes, a lighter flexplate will allow an engine to rev slightly faster. What you have to consider is the overall mass of the rotating assembly and then see the percentage increase from the heavier flywheel and not just the weight differenct between the two flexplates. I bet it is around 1% which should not be significant IMO. I did not notice any SOTP change when I swapped the flexplate.

 

Stock flexplate is fine. Tons of people are pushing assloads of HP on stock plates.
