Re: New to me '05 Yukon XL SLT 4wd - shocks?

I checked my RPO codes. My suspension code is the ZW7.
"Premium Smooth Ride".
Front shocks are conventional.
The rear shock is a Nivomac "self-leveling". It is combined with a softer spring, since the shock controls the height.
Which means, I need to get a firmer spring if I replace the shock, or the new shock will allow the rear to sag.

........ Crap.....

( I wonder if I replace just the front shocks, for now??)
