I already have a set of super springs on it. I was more concerned with the actual numbers. Thanks!
Yes, that will level and not squat as much...but the 'numbers' AKA ratings has embedded things for performance of that 'number'
Mainly braking of the load up to that rating..."numbers"
things like larger dia disc/drum, thicker disc, thicker friction material (therefore wider calipers and most likely larger dia caliper pistons) and even an more hidden component...the front/rear brake line bias valve (if yours has one).
Here is one for my GMT400 Suburban,and assume later models with 4 wheel disc has similar hidden differences


Tahoe/Yukon, Suburban/Yukon XL are all J or B 5 though 7.
Once into HD's, changes to JB8 and JF9
Most 3/4 ton Suburban's come with JD7's, but if the snow plow option ordered, it begets JB8's and the attendant components. Like larger bore MC, larger bore wheel cylinders and different front/rear brake line bias valve body.
All to stop the rated load to min DOT requirement for that load.
