Today I went to install kooks 1 7/8 long tube headers but unfortunately didn't fit,the headers was hitting the steering shaft.

I have a premonition that those shocks might wear soon specially that they are not designed to work with disconnecting power and what I read and understand that those shocks has a Magnetorheological fluid that might leak so I will keep the bilstien shocks in my store and wait to see how mag shocks works. guys,what I am trying to do is sharing my experiences with those issues that everybody is suffering I might fail and the things I done might work for sometime or it might work for ever so I will keep updating you gents.

The roof has been fixed twice by different dealers, and both of them did the same service bulletin that GM announced, for new tires I paid, and the tires I am using is half the price of the OE tires cost $600 4 set nexen roadian HP which worth every penny and I love these tires, now for the shocks, I know this dealer more than 12 years and they knew the car has those issues and gm could not have a remedy action so i will do it my self, when i unplugged the mag shocks,i took the service ENG for a ride to the worst road we have and he was so surprised how the car is smooth so i stop the car on the side and showed him what i did, off course he warned me that I shouldn't unplugged and GM wont accept but did gm care about us, for tune,offcourse if GM knew they will void, I don't have second row captains and yes its 4wd.

I got a tune and cancelled the v4 v8

I owned a gmt900 yukon denali for almost 8 years,the x denali had an autoride shocks and who had this car before knew how it is uncomfortable with high speeds specially over 87mph u feel like riding a horse,at that time i disconnected the autoride shocks and replaced them with normal gas shocks,the sevice manager said it is not safe and the car is designed to with autoride shocks etc etc,but let me bring your attention that the yukon slt and the lt tahoe both has normal gas shocks and they share with denali and escalade same drifetrain and subframe,my brother have mercedes g63 that cost double escalade and he replaced the oe shocks with other comfort shocks and the car run perfect,at the end this is the fix i think it will keep me enjoying and driving this suv.

i didnt pulled the fuse,i disconnected the wires clip in the that controls the mag shocks,just open the hood and u can see it on the right side of the shock,both side(you will get a message in the dash cluster saying service suspension system,i just ordered a set of bilstien 4600 shocks going to install them once they arrived,

after 2 days driving with new nexen tires and disconnecting the crab mag shocks,the car is so smooth and comfort.

OK guys,I just changed the tires with new nexen roadian HP 285/45/22 the ride improved slightly and I disconnected the front mag shocks and what an amazing smooth ride but I noticed when disconnected the speed is limited to 86mph I will put resistor to by bass the limiter,

Use glass ur getting old.

I do feel bad how this suv is vibrating and booming,i have been reading this post since the first day and most of the complaints is the same to my car,i owned 2015 Yukon Denali manufactured in April since the first day i felt the booming and the vibration, i took the car to my dealer to fix the booming issue,they just did the service bulletin that gm sent but the problem still exists then i took it to other dealer who said that the roof fix done by the x dealer was not done properly so they opened the roof and fix it again and it minimize the booming a lot,there is a trick which i think it work with me to put the recirculation mode off that i feel it helps reducing the pressure, just try,for the vibration,a road balance were done but still vibrate,then they replaced the rear differential and vibration still exists, i noticed the car the higher you speed the lower vibration is exist i drove 100mph for about 3 hours and the car was smooth reducing the tire air pressure helps rubber to absorb the vibration,what i am going to do now is to change those oe bridgestone to another brand which i tested on 3 cars i owned and i am going to replace all garbage mag & airshocks to a normal gas shocks and i think beilstein 4600 is the best.let me try.
