I want to lift my rig enough to clear 33X10.5s. The vehicle will be loaded pretty heavy when I'm using it so I am worried that if I get a lift kit with a regular spring rate it will really sag onces it's loaded down.

I don't want to use blocks etc. I want to do it right.

What lift kits would you recomend?

 

well it all depends on what your driving. 1st gen? 2nd gen? ZR2? 4x4?

 

It is a 1986 Blazer with a 6.2 diesel. Bone Stock.

 

I am assuming K5/fullsize with the 6.2 diesel...

I think that there are spring kits that are decent and if you are loading the back only you might want to look into an air ride load leveling system?

Just some ideas from me...
