Would these shocks be good?

Where so I start?

Upload pics of the springs?

Post model info about the shocks that I currently have?

Some pictures of the leaf springs, bushings and the shackles might give some kind an indicator. Or not. But it's a good place to start.

A K5 can ride much more decent without spending that kind of money though.

The difference between Tuff County or BDS and others like Rough Country, Pro Comp or old Rancho is night and day.

It's also all in what you're used to and what is expected. For all we know, the rig in question could already have high dollar custom springs on it, but it's "stiff" because it doesn't ride like a new Escalade. Or it could be on old 2.5" Rancho springs with an add-a-leaf and most any off the shelf leaf spring would be an improvement.

I thought read rough country, but you are 100% correct—it is possible @Edelbrock may be happy with a cheaper option.
