Spring advice!

I am running a 6 inch lift with blocks in the back. I sent an E-mail for some tech advice at one of the offroad dealers and he told me to run 8 inch springs in the rear and tha six in the front due to the weight of the Blazers. I am planning on installing zero rates to center my axle up as it is not centered now. I am thinking this will be to much as I do not even run a hard top on my truck only a soft top. any advice would be appreciated, he also said to order the 52 inch spring! any insight to spring size as well?

Re: Spring advice!

I run a 52" SuperLift 5.5" lift spring on the back of my 72.
The front I run 4" Rancho lift spring.
I sit level with no hardtop, at first I had a bit of stinkbugging but it has setteled over the years...

So there is some truth in that pre-made springpacks are built on Pick-up weight specs, not Blazers and Balzers do have heavy butts. But 6" in front and 8" in back may be a bit much..it's gonna stinkbug like crazy esp without a hard top. the taller the lift the less it's gonna sag as they get stiffer and stiffer the higher you go.
I say 6" & 6" w/zero rate in back will be perfect!

All just my opinon..about 1.5c worth hahahaa

Re: Spring advice!

I have a skyjacker lift on my blazer, and it came as a 6"/8", for a blazer. I don't remember there being a huge differance in stance, with or without out the top on. It always looked pretty level to me. Now you have about 3c worth. LOL!

Re: Spring advice!

How wide are our springs on the blazer? I am currently working over seas and trying to order some stuff for when I get home. Thanks for the advice so far. figure the springs are original from 1972 probably would not hurt to replace them anyway! I believe I will go with the zero rates and 6 inch springs!

Re: Spring advice!

8" lift springs will ride like crap, go with a set of 4" springs and a shackle flip.

It'll net out the same amount of lift and you'll like it a whole lot more.

Zero rates are great but if you end up ordering a set of springs, just have the correct pin dimension built into em.

Thanks VT Blazer!

Have been talking with a vendor and that is the same thing he said, currently have blocks with the original springs. seems to have axle wrap on hard stops! all hardware is tight I just think those 29 year old springs are tired!

Who do you recomend for the springs? any dimensions I need to give or are the kit ones good enough?

I am out of the country and trying to get boxes in the Garage so I can have some relaxation Blazer style when I get home!

Thanx
