@PopeyeD Thank you for your feedback. My truck was fitted with 265/75r16s from factory. When my dad handed the truck down to me the tires were extremely bald and needed an alignment. The tires were put on in early 2015 and last alignment was who knows when. I will be changing my shocks and things in the front end like I stated then getting an alignment. Hopefully that fixes my problems. I will keep you guys updated. I relate heavily to your “Every bump, dip or pebble on the road could be felt with a bang throughout the truck.” Mine does the same thing, with new tires that don’t even have 500 miles on them yet. General grabber Atxs. If the problem continues to worsen I’ll consider selling my tires and wheels and going back to the stock wheels and getting a nice set of Michelin’s!

Maybe one day I’ll look into the coil over kit. I appreciate your time

Yes, another topic about rough ride. I've read a couple forms about everyones rough ride, but i feel like my situation is a bit different. I have a 2003 gmc sierra regular cab short bed, z71 with the heavy duty towing package. Truck has 146,000 miles on it all original. I have about a half inch of room in my keys. They are not turned up at all. I have 20 inch takeoff wheels of new denali. I also just bought new beilstein 5100s, ilder arm, ilder arm bracket, and pitman, arm. Does the z71 package have something to do with the bad ride because of the gas shocks? Or is it the heavy duty towing package? Some people have said its because of the short wheelbase. I have a bad back and knees and I hope someone can give me some guidance. I understand its a 19 year old truck and it wont ride like a Cadillac but surely i can improve it. Thanks! Edit: (Forgot to mention My tires are 4ply and 275/55r20 very very close to factory size with 35 psi in each tire.)
