mdehoogh already said it, but the ZR2 bars will fit. You may not want to or be able to turn the T-bars up after installing the ZR2 bars since they will likely make your truck ride a bit higher with the same bolt height. Here's a link to a thread where its discussed in pretty good detail, including the torsion bar measurements.

You also should check your shocks if your truck is riding like a boat. The shocks are super easy to change in our trucks. Good luck!

 

Yeah the whole suspension is gettn an overhaul. I'd like to get some good beefy shocks but not really sure on what to get cause I want to lift it. Like will the standard shock get stretched out with the lift or no?

 

Lol that's the link I got the idea for the zr2 bars from. Just wasn't sure one how compatible things are.

 

Any of those T-bars would fit your blazer. I have a set of ZR2 bars that are going in this weekend. The hardest part is finding some for a decent price. As for the shocks, if you're lifting your truck you definatly will want to consider longer shocks. With the factory shocks you will have the problem of them maxing out when extended rather than the suspension maxing out (ie. your control arms will be hanging from the shocks when extended).

 

Thank you that's what I was wondering.

 

2wd half ton chevy nd gmc trucks should have the same bolt pattern for the 88-98 body style, nd i think the same with 73-87s too

 

Yeah I read that too but mine is a 99 so would that be different for me?

 

I'm not certain, and if anyone knows for sure please chime in, but I think all the 1/2 ton trucks with a 5 bolt pattern were a 5 on 5" pattern, where ALL s-series trucks are a 5 on 4.75" which is shared with most RWD chevy cars. I'm fairly certain that the rims from a full size chevy truck would not fit our S-series trucks.

 

See that's where searching the internet kinda sucks cause you get mixed answers. I know I got the 5x4.75 so ill probably just search for aftermarket rims with that bolt pattern so I know for sure they will fit.

 

well my friends rims off his 2wd gmc c1500 fit on the blazer no problem
