Default ZR2 Rear Sagging

I just bought a 2000 Blazer ZR2 and i noticed the rear is sitting much lower than the the front and i cant stand the look of a saggy rear. So my question is how can i fix this and where do i get the parts from?

I believe every ZR2 you will see will have that same back end sag. It has to do with the suspension of the ZR2. I just put an add-a-leaf from JCWhitney on mine. It raised it up 3/4", which wasn't as much as I hoped to perfectly balance it out, but it was noticeable and did even it out some.

For free you could always look into cranking up the rear torsion bars to even it out. It will increase wear on your truck though.

Lots of people suggest getting shackles from Daystar.

You can get shackles or add-a-leafs from them.

A quick search will answer all of your questions. This has been covered many, many, many times before.

Oh, and welcome to the forum!

There are NO tbars on the rear of any blazers. Only leaf springs.

I was looking around at Advanced and they offer a shackle kit with holes drilled in it to adjust the height. Anyone use these? Also do i have to lower the gas tank to get the old shackles off?

I've got 2" shackles in mine and didn't have to remove the gas tank, although things where pretty tight up there. I can't remember if I had to loosen the gas tank shield and drop it down a bit or not. Once you get under there you'll know what you need to do.

The advantage of shackles over add-a-leaf is the ride will not change. If you like how the suspension is currently, go with shackles. If you want a little stiffer suspension, go with the add-a-leaf.

Or the third alternative is to have your springs re-arched or replaced with new. The first two option are cheaper, though.

ive seen people take the main leaf out of a spring pack and stick it below your main leaf. it was done on a jeep cherokee with two s-10 main leafs. probably get them at junkyard. might cost 10 bucks. then u need new center bolts and maybe longer u bolts. it lifted the jeep up probly 1.5 inches. made a significant difference.

I wouldn't use flat stock steel in place of a leaf spring. Although [cold rolled (steel that is rolled out in a low temp.)or hot rolled steel (steel that is rolled out in a high- just under melting temp.)] is flexible, it will crack or tear if flexed repeatedly. Use add-a-leafs or add some used leafs from a yard as suggested. There is a reason that they call the steel used to make them (spring steel), it goes through a heat treating process that gives it the ability to spring back to a set shape after repeated flexing without cracking or tearing. Of course everything has it's limits or we'd never hear of broken leaf springs. Old age or too muck weight will break anything!!
Trust me, I work in a tooling division for a foundry that does their own heat treating. It's some neat science in how you can start with similar stock, run it through a different process and have totally different results of hardness, fracture rates, ect.
Don't use flat steel as a leaf spring, it will cost you somewhere in the long run and me be a hazard to your own safety!! The used junk yard springs is the safe cheap route.
