03 Yukon Xl Denali Shocks

[Tage]

My SUV has almost 100K miles on it and it rides like crap. My lowered Honda is much smoother over most roads. I'm guessing my shocks are just worn out not doing much and replacing them would be a good idea. After some research some people are saying it's a bad idea to replace them with anything besides the original shocks since it will throw a check engine light and the traction control may not work anymore. I'm fine with that but I'm finding they are super expensive.

 

Checking on online I'm finding several super low mile OEM shocks off a 2007 Denali for a fraction of the cost. Are 2007 Denali shocks the same as 2003 Denali shocks? Any difference between the regular size vs XL?

 

In case it matters, the VIN is 1GKFK66U23J144492

While I don't have access to the parts catalog, I would bet they won't work. However, if no-one else has answered you by Monday, I will go to parts and check for you.

Thx for the reply. I've emailed a few places and I still don't have an answer.

Tage,

 

I cannot be sure, but does your Denali have the Autoride electronic controled shocks? If so, they are very expensive. I have read a few posts where people have replaced them with traditional shocks.

 

You could have the Premium Smooth Ride option which is ZW7 I think. If so, the front shocks are typical shocks but the rears are called "self leveling" and made my Sachs. You have to replace them with the same type shock and to my knowledge, nobody makes them other than Sachs. Our supplier, KYB offers them but they are repackaged from Sachs. Our part # is SR 2004 but be ready, they are very expensive. I have also read you can replace them with traditional shocks but you have to replace the rear coils as well.

 

If you do have the ZW7 option, I would recommend you go back with the same type rear shocks and KYB MonoMax shocks on the front. I still have my rear self leveling units but I have KYB Mono Max on the front.
