have mechanic look at your MRC shocks. they could be bad.

there are also some MRC updates the dealer can program in.
i have seen a few posts here on it.
a TSB exists, your service writer can look it up

MRC + 22’s + 2015 = loosen your fillings ride.

I special ordered mine just to get tires with less rim and more rubber for that exact reason.

So, short of a tire swap, check with your dealer because there have been instances where MRC was locking up shocks and making an already rough ride unbearable. They may be able to apply and update or software fix.

^ sounds more like 26" & up lol

mine rides great, but i like somewhat firm.
i cant stand sitting on a marshmallow while driving on a cloud, kind of ride

thank you i will check with the dealer ... i know this may sound crazy but i feel there is a sweet spot where it rides great then at times its crazy bumpy do these shocks stiffen up at higher speed i just feel like its not consistent

update:: took my tuck to my mechanic turns out both struts in the front are shot both need replacing he tried to do a software update first that did nothing so no i am changing both struts

What is the software/firmware update everyone is talking about? I have a 2015 Yukon XL Denali that rides rough. I have asked about TSB stuff at my dealer and they say nothing doing.

I had both front struts replaced at 56k miles. Just got told they are leaking - 50k miles later. Ready to delete MRC.
