I noticed that the 4x4's sit higher... I was wondering what the actual spring lift height is on the stock 4x4's... I'm going to straight axle and 4wd convert mine over and I'm looking at what springs I need to pick up.

Thanks

ya might wanna check with the guys over in the 4x4 section and see what their opinion is.....but I kinda found my 3/4 ton 4x4 sagging in the front(negative arch) and added an add-a-leaf kit on the front. I probably could of got away with a new set of 2 inch lift springs upfront and found that to be just a good.

The negative arch is the way it came from the factory.
Bigred:If I was converting a 2wd to 4wd,I would use a 4" tuff country lift.Is Your rear trailing arm or leaf springs?It takes a lot of planning.Steering needs to be changed.Maybe use a cross over setup.Spring hangers,transfer case..i would use a divorced case.
In the long run it might be easier,and cheaper to get a 4x4,or a 4x4 frame.

Stock 4wd is no lift.All lift kits are based on how many inches over stock they raise the truck.I think what you arewanting to know is how much higher is a stock 4wd than a stock 2wd?You will need stock replacement springs if you want stock height.If stock height is not what you want,then start with what tire size you want,then get springs that are right to fit those tires.4wd Blazers in these years are abundant in complete yet rusty and cheap form.Buying one for a parts donor would be the most practicle way to go.You can keep the rear suspension you have.But,normally 4wds have leafs at all corners.If you have rear leafs,then the only diffence is the springs will be located wider than on the 4wd.So,to use the matching rear axle,you will need to relocate the saddles on the axle.If you`re lucky,you will have the same ratio as the donor and no rear swapping will be required.
