I just bought a 2000 ZR2 Blazer with 84000 miles on it. The back sags so much I cant stand looking at it. Which would be better some air bags or shackles? I'm planning on buying a small trailer and a dirtbike this spring and the air bag idea seems cool because I could put more air in them to level the load out. I know the shackles cost about 1/3 as much and that Synergy Offroad makes an outstanding pair in different sizes.

But you guys know alot more about this stuff than I do. So what do you think is best?

 

i would bag on a leaf spring it will give u a softer ride when towing plus the leveling u need if u have ever road in a full size with helper bags u can feel the difference it makes thats what i would do.

 

Ok well I have air shocks which are easy to install, pretty cheap and I swear I got a 2 inch lift out of it.

 

I say Shackles

 

I say shackles too because they are cheaper and better.

 

Both options will help, but won't fix the actual problem. I would consider having the springs re-arched or buying new springs.

 

I just installed my new shackles.. I got them from Knaffle on zr2usa.com-

I have shackles, AAL's, and air shocks. I'd go with shackles first.

 

all of those previous answers will work like rearching the leafs and so forth but when u want to consider ride quality air shocks and bag on a leaf willgive you the best ride

 

Holy crap...is it still up on jackstands in that second pic, or did you get the 6" lift shackles???


I've always been leery of the concept of air shocks. Seems like the shock mounts weren't really meant to hold up the weight of any vehicle, and with air shocks, that's exactly what you're doing - transferring [at least some of] the weight from the frame points that were designed to carry it, to points that weren't. Granted, shock mounts have to be strong enough to stop bounce, which can create a lot of force, but it's not lasting force. Holding up the weight of a vehicle is 24/7 (unless you're upside-down ).
