I've noticed the rear on my blazer is sagging a bit. I have also noticed that all of my shocks are shot.

I'm not looking for it to be an extreme off-road machine, but I will be using it for hunting and fishing and to get to hard to get spots.

What can I do to raise the rear just a bit, and what are some good affordable shocks that will work well when driving on the highway, and when I am going off-roading.

 

you could buy aftermarket shackles that could raise the rear around 2 inches.

 

How does aftermarket shackles affect the ride, shocks, drivetrain, etc.

 

Shackles leave the ride quality the same...
Add a Leaf which also raises the rear gives a more stiffer ride...
while an air ride will give you a smoother ride, but costing a lot!

If you want the front higher you can do a T-bar crank, which is for 4wd blazers, 2wd have springs...
cranking the t-bar makes the front end wear faster!

Or you could go the bodylift route ($200ish) and life the entire blazer 2-3" this will not affect the ride quality or cause premature front end wear.

 

Look at Monroe shocks that too expensive. I've got those on mine blazer

 

I've got Monroe reflex monotube truck shocks and they are quite nice riding.
