2006 Silverado 4.3 Clutch Swap

[DMC0722]

I have a 2006 Silverado WT with the 4.3 and NV3500, and am in the process of ordering everything for a clutch swap within the next week or so. I'm almost fairly certain I want to go with an Exedy clutch kit, including master and slave cylinder. I've used Exedy before and have been happy with it thus far. What I really can't decide on is what brand flywheel to use. I'm leaning toward a Sachs NFW1055, but I've only seen one review on it and the person mentioned it was incorrectly balanced and it had to be sent back. Just seeing if anyone else has done a clutch swap on a 4.3 and what brands were used. I probably wouldn't normally ask, but Exedy doesn't appear to make a flywheel for this truck, leaving me to find an alternate brand flywheel.

 

Also, the main reason I'm doing a clutch swap is because the truck shifts and drives horrendously. Grinding gears, clutch pedal engaging at the floor, jerky engagement, etc. I've seen mixed information on different forums about this issue never really being resolved and some people never get a properly functioning clutch before it's over. I've seen comments as simple as someone had the same symptoms and swapped the clutch and it drove like new. Then I've seen people say there is a GM service bulletin out over trucks assembled in Mexico using the wrong master cylinder and a revised replacement part has to be used, a clutch swap has been done with little change in symptoms, etc. I'm hoping replacing the entire clutch system will take care of all this. Input on this would be greatly appreciated as well. Thanks!
