Also, as long as your old bolts are good, I'd recommend doing a thorough job of cleaning the threads of all remnants of the thread locker. A decent wire brush along with some acetone (for dissolving the TL) works well. I'd also run a thread chaser through to clean the internal threads. Reapply some fresh TL and your good when torquing them down.
Thanks, Sam

With your setup, I would stick with the stock setup. People are running considerably more power through them with no problems and there's no need to upgrade and chance the possible NVH issue.

I run dss poly couplers on both ends... when I first installed them there was a slight vibration on takeoff but after awhile it totally went away, I'm not sure what caused it or why it went away... I didn't notice any runout on my shafts when I installed everything but the only thing I can think of is that either I did have a minimal amount of runout or the couplers weren't perfectly true and that caused the vibration upon initial install and it went away after the couplers wore in the area(s) they were rubbing... if you don't plan on going over 500rwhp I think the stock gm couplers should do just fine... if you have the older 10mm torque tube I would consider swapping to the 12mm tube/couplers

yeah I don't think you will need them if you're gonna stay under 500rwhp... I am also thinking about upgrading to a dss 3.5" billet driveshaft when I get around to doing my tr6060 swap, things get out of hand fast

If you want to confirm then call a few reputable companies like RKT Performance, RPM Transmission and The Driveshaft Shop and see what they say. DSS does lists 10mm auto and 12mm 6-speed shafts on their site for 01-04 C5's.

If you insist on using a poly coupler, at LEAST go with the DSS couplers. FAR more robust.
