A Rocky Road - a 2017 Suburban z71 Build Thread

[BigBoyZ71]

Starting a build thread as I dive deeper in my modifications. My ultimate goal is a weekend overlander/roadtripper to explore the eastern Rockies. Coming from lowered Subarus, it's a far departure from my automotive expertise. I've exclusively driven and modified EJ25-powered Subarus for the last 13 years.

I started with a 2017 z71 Suburban [Midnight Edition] with 140k KMs, in pretty neglected shape. Acquired in the Fall of 2024.

I've got some minor mods already installed, and I'm slowly researching and stockpiling parts to get it where I want to be.

The Suburban's long wheel base will limit some of the off-road trails that you will be able to navigate, but that's a minor issue.

I have no experience with either lifting or lowering these beasts, or going offroad, as my truck is a street runner rig, so I cannot assist you in providing useful information and recommendations.

However, lots of folks in this Forum do lift their trucks and go offroad, and they will chime in. @the 18th letter

I wish you the best of outcomes, and I'll be watching your progress.
