Hello, all. First time posting on this forum and hopefully it’s a good one! I just recently purchased a set of FOX 2.0 coil-over front strut assemblies(982-02-018) and rear shocks(980-24-660) for my wife’s 2015 Yukon XL SLT. I have searched and searched with no prevail for an informative write up about the adjustments for this particular coil-over. With a full toolbox and the facility to install these suspension components at my disposal, I figure I might as well dive in deep and document my results to share with others. Unless this has already been done and I’ve been searching all of the wrong keywords(wouldn’t surprise me). If so, or if someone has some real-world experience with this particular setup, please share! This is a community after all.

Let me start by saying these are not yet installed on our SUV. So far, I have reached out to FOX technical support in regards to the preset and adjustment feature of this coil-over. In an email I received on 8/1/22, they claimed that these are preset to 1” of lift right out of the box. I have seen a lot of different opinions and results on this, but I will take their word for it….for now. Some say they gained 2-3” and some say it’s different because these will also fit on a GM pickup of the same year(s). Either way, I plan to figure this out for myself and get to the bottom of this for the community. When I asked them about adjustments, they said that preload has a 2 to 1 payoff. For example, moving the adjustment nut 1/2” up or down, is equivalent to 1” of lift or drop at the wheel. Again, I plan to take the time to confirm this to be 100% accurate information.


That’s it. That’s all I have for you guys right now. Hopefully I didn’t bore you too much. As I work through and finish the install, I will post my thoughts in here. I encourage you chime in too! Always open to hear what others have to say. All I ask is that you please keep your post informative. There are other threads that will show you what these trucks look like when they are leveled and this isn’t one of them. Cheers!

I installed Fox 2.0 (985-02-018) on my 2016 suburban. It raised the front end 2.5 - 3”. After driving about 200-400 miles it settled about 3/4”. My passenger side ended up being 1/2” higher than the driver side. So I adjusted it and got them to be even.

I have the Magneride in the rear so I did not do any lift yet on the rear.

Had the same exact setup for a long time….worked very well for us!
