I'm looking to find a lightweight flywheel for a 2003 silverado 4.8L using the stock NV3500 ... the complet powertrain is gonna be use in a 2500 lbs car ! I've check exedy, center force, spec, fidanza and didn't find anything ! would a flywheel and clutch kit from a LS car work as is ? the input shaft is 1 1/8 10 spline !

 

im in a similar situation. im lookinf for a 26 spline disk and performance pressure plate that will bolt up to the truck flywheel.

 

A small update, we ditch the NV for a T56 since parts are rare !

 

for something that light, a t56 is a much better choice with lots of available performance parts. though the nv3500 has decent strength, the gearing is terrible for any type of performance driving
