my rear end on my s-10 blazer is really starting to sag. I dont do any towing and the most i carry in the back is a spare tire and some other junk that
dont weigh a whole lot. I think that over time they just wore down.

What i want to know is what you guys think i should do in my situation . I also need new shocks in back. but mainly i just wanna know if i should get
add-a-leaf or all new leaf springs. also what brand do you think would be best ?

 

Definitely change all the leaf springs, and while you're at it you can also do add-a-leaf. Also if the back of the truck bounces a lot then change the shocks. My friend's 95' 4runner sags in the back and it annoys me lol. I have yet to see a Blazer that sags. Usually those heavy duty leafs hold up until it's time to junk the truck 15 years later.

I have no preferences on name brands though, but anything goes as long as you get it from a good website.

 

Like dim said get new or newersprings and shocks. Then an add-a-leaf. I called around here for mine and can get a set with 50,xxx miles on them for like $40. Which is better the my 157,xxx. I would get a long add-a-leaf as it is not supposed to be so rough.

 

I have a short add-a-Leaf and I didnt nodice a change..Just a nice little pick me up in the rear end.

 

It cost a little more but if you have a local spring company check with them.
We have warren spring co. about a block before the middle school here so last week when I was picking my son up after school I stopped in they said $250 for completely new spring packs for both sides for the rear of my truck (4 leafs per pack vs. the 3 leaf pack that was stock) they claim 1.5" height increase over factory (not over the current sag but over what they were when the truck was brand new I made sure they clarified this point) and if it doesn't bring em the truck and they will put custom made shackles on for me to get the height I want at no extra charge, sounded good to me! I'll be picking up the new springs at the end of this month (2 week lead time). I know shackles and an aal would have been cheaper but being a 94 mine are kinda old and saggy so I chose this route for ride quality and the fact they should last a good long time.
