need help with 2004 GMC Yukon XL

[skyhighsami]

My wife has a 2004 GMC Yukon XL lowered 3-5 with 22x9.5 305/40/22s and SSBC 14" brakes all around. The problem is that is rides EXTREMELY rough. I did the free travel mod and it is still very stiff in the back. My question is it the coil or the shocks and if it is the shocks what are good ones to try? I have gone from stock, to Doetch Tech, to the DJMs that came with the kit. If it is the coil what is a good option to make it ride a little more like stock? Thanks

get shock exstenders and use ur stock shocks
thats what blizzard did on his denali and it rides stock on a 5/5 drop

I was told that I actually have the wrong coil springs. I will try that and if it doesn't work then I will try something else.

Well, since I was asking questions in a thread about a 3-5 drop and was told to start my own thread (WTF).......anyway I have the correct springs, lower control arms recloated, sway bar relocated everything is done. So should I get new coils, or shocks first? This weekend I am getting my dually from being bagged and next going to Houston for TX2k10 so it will be the following weekend. I am thinking about getting a steering stabilizer, Bilstein shocks, and maybe sway bars if they are really worth it. Another thing the sway bar isn't hitting the panhard bar either.

Will the new sway bars change the ride or anything? Also how useful are new control arms?

Will the new Eibach or whatever sway bars change the compression and rebound or make it stiffer other than through the corners? Also are the new trailing arms in the back really worth it? Another question I have is once you lower the axle 5" in the back does it move the axle more to one side? Reason I ask is when I put the wheels on my truck the right side was rubbing but the left was fine. That makes me wonder if pan hard bar swing the rear end towards the drivers side the lower you go. If so would a new pan hard bar help center the rear better? I know I am asking a lot of question but I want to understand as much about this truck and making it ride as good as possible.

Hey Steven i know i posted this some where else i can't seem to find it now but i'll post here again. This is what i did to get the ride finally running smooth

Suspension Mods:


3/4 Ton Chevy Stock Torsion Keys in Front 1" to 3" Lower - This actually made the suspension travel much more then stock keys their for allowing the ride to be much smoother

AIR LIFT 1000 Series Rear Air Spring Helper Bag Kit #60769 - Helper bags i haven't installed them yet Hopefully this Saturday i'll get them in , I've only heard that this will stiffen up the ride on the back so if you have any bounciness like i don't have then this might help you, It also says on the box that makes the ride run better and smoother, I only got this cause when i pack my truck with people on the back or whenever i tow something i will have air on the fly to level out the truck since truck sits lower then normal

Belltech Street Performance Rear Shocks - These shocks are perfect, I remember the first time i put them on i notice a big difference in overall comfort and seem to have a sportier feel to it

Belltech Street Performance Front Shocks - Same thing for the front wasn't as bouncy or clunkiness

DJM 5" Rear Coil Springs - Nothing to complaint about they get the drop done

Z71 Front Bump Stops - still has the same amount of travel but should ride better

DJM Rear 3/4" Urethane Rear Bump Stops - hopefully have these installed by Saturday also, this should eliminate the Bottoming out problem

DJM Free Travel Mod - from my experience this was the scariest thing I've ever done to my hoe just the fact of cutting something off from the chassis was a very scary feeling but i gotta say with the help of members this is by far the best mod you could do to your truck this will eliminate all bottoming out problems and Improve the ride Way better. This is Mandatory

Eibach Front & Rear Sway Bars - I notice a overall more aggressive ride not Harsh but it felt like a 5 Series BMW, Difinetly less body roll, more in control of the truck, My truck feels very stable at high speeds and well planted.

McGaughy's 2" Drop Spindles - The drop spindle was by far the best mod for the front suspension you could do.. Notice a more plush ride and less jerkiness this got rid of the civic bounce

KYB Steering Stabilizers shock - I'll have this installed hopefully by this Saturday..


Hopefully this helps you out good luck
