What all do i need for a 3.5-4" lift Badlands Sasquatch?

[87-Z28]

Just from a pure, very simplified, static loading perspective. You can calculate an angle metric for tipping, based on CG and track width. This is only useful for a basic comparison. It does not consider dynamic factors or suspension response, so just a giant static rigid block. But it does serve as a reasonable baseline for how CG and track width play together.

Like @5GENIDN said it is more complicated than this. The suspension dynamics can help or hurt the tipping response based on how everything is setup. However, the basic static geometry still provides the baseline and it is always best to start from a good baseline.

Some plots attached. Notice the added width for the portal rig on 40s makes tipping angle metric similar to a typical build on 37s, but much improved ground clearance. The half portal rig on the plot is what @SierraBronco was trying to achieve with his CG location.

We need to update the chart to see what the final setup is like as we’re 93” wide but only 91” tall.

Attached is a picture comparing our mullet portal rig with 5.5” of portal lift compared to a normal portal rig with 4” of portal lift. Both on 40” tires.

So which of these two kits is the better one?

Rock Krawler

Or.
king

Are there other kits in this price range?

I do not think King has a kit... They have coil overs.... Rock Krawler has a complete kit that includes the coil overs.
Edit... you linked to a Acutune kit with King coil overs.... Pros and cons to each.... I would not say one is "better" than the other.

AND while you are at it you might consider Acutune's Ride "kit".... I love my kings but if I had to do it over I would strongly consider either the Rock Krawler or the Rides.....

Looks like the Rock Krawler dampeners are single valve adjustable like the Kings. The rides are dual stage adjustable... I would want to know more about the spring rates in both. Rock Krawler suggests theirs are multi-rate... I would assume progressive but I would talk to them and find out.
