How are the instructions for a mechanic of need, not profession?

Just take out old springs and put in these ones and take out old shocks and put in these ones

Will this fit my 2002 gmc envoy slt?

Check the year range…I put them on an ‘07 Buick Rainier, same platform as the Envoy…pretty sure

I tow about 3000 lbs, will these handle that type of weight or will the suspension sag down as if the airbags were still on it?

These work great. I tow 5,000 lbs with no problem. The only thing is it makes the car sit high in the rear so I had to put some clamps to retract the springs a little.
