I have a 2003 Chevy Silverado 2500 HD with the 6.0 L engine. I have 285/75 Dueler M/Ts on it. I bottomed out on a set of RailRoad trax not to long ago and blew out the rear shocks. I have replaced them with Edelbrock IAS shocks but feel that they are too stiff. What type of shock have you found to be the smoothest and best ride quality on the highway?

Thanks for the info.

Yes it does have a bug deflector on it, don't know when the truck started making this sound at higher speeds because I hadn't taken it on a road trip until last Friday and the speedo had not seen 55 in town.
Any particular reason the bug screen could be causing this sound, I have bug screens on all of my trucks and have never encountered this before ? Maybe a difference in the cosmetic designs?

Thanks for the reply. I have put the new tires on and yes I feel that the new tires are not as good on performance. Not as bad as the original but just slightly worse than the previous 265/70/16. Oh well, I guess I can't complain seeing that I got these brand New for $350.00 with rims and everything. As far as truck performance, I'm not that much of a lead foot and I think that the truck is trying to "learn" the increased effort to gain momentum. 80 mph does not feel comfortable driving as before. I know that I'm off on the odometer and that the new 80 mph is probaly closer to 85 but It just doesn't feel "right" Do you think It would be better to reprogram the Transmission? I have a 4.8 with 3.73 locking rear.

I don't know about reprogramming the tranny. Mine was flashed due to a "clunking" problem and it helped. Although now it feels slower to downshift, which doesn't help the lower-power from the big tires. Oh well, it's just a run-around truck anyway. I would at least have them reprogram the speedo. You might consider one of the custom programmers though. They come with a speedo adjustment, tranny program, as well as power programs. I'm not sure what the true gain in power would be, but you might find that a better investment than paying the dealer just to reprogram the speedo. If I was keeping this truck long-term, I'd buy one.
BTW, I've got the same truck basically, 4.8L, 3.73, ext. cab 4x4. I probably wouldn't buy the 4.8L again, the 5.3 in my Tahoe is a much better motor IMHO. I don't think there's much difference in MPG either. The Tahoe always gets better mpg, but it's used on the highway more so it's not easy to compare. The truck usually doesn't average over 16mpg.

Thats your problem ! Take it off and try it out.
If no noise with it off....thats the problem!
Then you will do the windsheild surround reseal.
Search back thru this thread. There are posts on how to do it yourself.
Poss. one of the folks here who have done it can post and explain it fully for you.
EDIT......Check Mitzis post #4489 for the windsheild reseal TSB #
and give that to the dealer if you want them to fix it !
Thanks Mitzi........I missed your post on it !

I had upgraded from stock to the Edelbrock IAS and also found it way too stiff for my liking. I changed to the Bilstein HD and have been very happy since. Plus they are cheaper than the Edelbrocks.

Thats what I thought. I had a lifted Z71 Tahoe with the Bilsteins and enjoyed the ride, but wasnt sure if there was a different shock that would ride as good on the Silverado
#4500 of 5688 Silverado Transmission problem?
Nov 11, 2004 (5:04 pm)
I have a 2003 Silverado SS and I had a problem where upon quick acceleration, the RPM's redlined and the truck didn't go. I had to have it towed to the dealer who said they had to replace the shift solenoid. Problem happened again recently. Has anyone experienced a similar problem? Truck only has 11,000 miles on it.

I wonder if the truck is running up against the rpm limiter?
