Leveling and/or Lifting 2021 GMC Sierra SLT

Thanks again.  I am looking into it and Eibachs team is supposed to call me back.  As of now, they do not have anything for the 3.0 duramax deisel.  I was transferred to the tech guy who wasnt in at the time.  But I will keep checking.  Thank you again for taking time to send me the information and not being a d@#$ about it.  Appreciate it.  

 

Out of curiosity, what are your thoughts on removing the spacers from the front and adjusting the Bilsteins B8 5100 adjustable right height struts up to 2.5 inches and keeping the 1.5 inch rear block in place?  How much settling do you think would happen with that.  

 

Thanks.

Adjustment of the shock itself will directly correlate to changes in handling characteristics.  Generally, the higher the adjustment(elevation) you go on the shock, the harsher the ride is.  However, I haven't personally adjusted any of the 5100's so I would verify my assumption with an individual who has direct knowledge of that shock's adjustments and subsequent changes in handling.  With my Eibachs, the higher you adjust them, the "stiffer" the ride gets and if you don't have a lot of weight on the front end(winch or aftermarket bumper), the highest level can be harsh.  My guess is that the reason Eibach doesnt have a shock setup for the diesel trucks yet is because the additional weight on the front end of the truck requires a retuned/revalved shock, different from the gas motor vehicles, and they simply haven't gotten around to it yet.  The suspension components themselves appear to be angularly identical, but I haven't verified that with any instrumentation or empirical data.
