will chevy trailblazer leaf springs work to put together a bastard pack?

 

I don't think trailblazers have leafs in the rear.

 

The s10 blazer or pickup springs will work. That's what i run.

 

which leafs do i need, how do i set them up,and what would be the height difference with the pack and a chevy shackle?

 

A lot of guys cut the eyes off the main S10 spring and place it beneath the main spring in the XJ pack. How much lift you get depends on the condition of your XJ packs and the condition of the S10 springs ... but it can be anywhere from 1.5 to 3 inches.

Bastard packs are a decent, inexpensive way to get lift .... and they work fairly well .... but they do shorten the life of your spring pack and they usually result in a fairly rough ride.

 

I used my main eye spring and then the chevy eye spring with eyes cut off then inter mixed the jeep and chevy springs into the pack. Mine ride great and flex really good. I used a lift shackles and had 4.5" when done.
