basically every thing i need for 100 bucks. i have concerns about ride/noise afterward but we shall see. im picky...
Curious to see how these do, mine bucks like a bronco (exaggeration but still) on concrete highways.
Frankly, I think the poly rides better than OEM; BUT, there's increased engine vibrations at idle - enough that sometimes interior panels (my passenger door rattles).
However, take my recommendation with a grain of salt, as we both know: ride quality is an individual perspective that differs greatly - as I personally hate being in vehicles that feels like they're floating/disconnecting with the road or body roll.

they will most likely make it worse based on everything i know.
exactly. im all about the floaty ride but this is a big truck, specially when towing so i need to keep it fairly street friendly. im hoping that cause the air bags made the ass end of this truck bounce so bad over the past few years that when i put these in, i wont hardly feel a difference. plus the fact i have some really worn out mounts. fingers crossed lol
Here's a list of what I have.
The first number; starting with 15; is a GM number & the "Other #" is an aftermarket number; Dorman for example.

Sorry to fail you James and it take so long; work is crazy busy right now and with this baby fast approaching my time is gone... haha
Let us know how you like those mounts. I've thought about replacing mine just b/c they're original from 2003.

Threw them in today. My cooling fan is hitting the fan shroud at the bottom. Found that interesting. Shimmed it down enough for a test drive. Body is level again with the bed and so is the core support but I think I found the reason. More on that later
First off, These things are definitely not "cushy". You get much more road noise and added vibration but at the same time i had a better ride over rough stuff on the road. You can compare it to like being a unibody car road noise and vib wise.
I think I can live with it. Only time will tell. I may try taking some preload out of the bushing and seeing if that helps soften things up. If so, I'll lathe them down a bit.
As for the fan issue. My buddy was videoing the engine as I was torquing it up in reverse when it would rub. Come to find out my passenger engine mount is shot. It's the original from 01. Guess it's time for a new one. May shim the engine higher too if it's still not enough

Thanks for the feedback on the prothanes. I think with your input I'll avoid them. I like a firm ride but undue vibration drives me nuts. I'm hoping just getting new OEM ones along with my new leaves it'll improve things. Sick of taking up bed space with 300 lbs of sand 
. Without the sand it is a bucking bronco from 35-70 depending on the road

Shocks man, mine bucked bad. 20 dollar monroes did fine.
I'll get a good set now that I don't have all the weight beating the shit out them.
I've never gotten more than 30k out of a set of rear shocks. Usually 20. It may not be but a lot of shocks that dampen as well as rebound makes them bouncy.
I'm about to pull the trigger on the poly's for my LMM. Curious about that door alignment though.
I found out the other day that at about 75 mine gets very carried away in the bucking department/frame beaming. So much so I had to stab the brakes to quit popping the throttle. New setup all around with new hydraulic mounts in the rear and maybe new shocks...5100s were nice when it had a ranch hand and a utility bed to weigh it down but something softer is in need

Obviously mine isn't the same but no shimming here. Everything lines up great

I won't say it induces vibration, it just allows more road feeling and so on to be transferred to the driver.
I'll say this, I'm taking them back out and selling them if anyone is interested once I'm back from vacation this week. These just ain't my cup of tea so dormans it is.
I'm not sure if the 07 classic and your truck use the same mounts. But if the do rock auto has the dorman radiator, 1st position and 2nd position. They should have the third position too, but you will need a part number to look up on there and they should have it. I don't know why it is not listed. I can give you a 5% discount code to use too or you can Google " rock auto discount code".
The part numbers given in here will cross reference over to the Dorman stuff on rock auto. I have their 5% off coupon too but thank you Mike!
