Quick Leaf Spring Question

[tanman_2006]

I am buying a set of 2004 3/4 ton duramax springs off of a pretty much street queen truck so it has never towed and is now lifted, they have 90K on them. These are going on my Z71 :hihi:

I would like to install new bushings in the leaf springs which do i need?

how are the lengths and widths compared to GMT400?

If i understood right that cheaper one has only frame side shackle bushings, but that more expensive has all bushings for 2 leafsprings and shackles.

The springs themselves are a direct swap but i think the frames are different so the spring perches are different on the newer axles.

Thats what I thought too but wanted a second opinion.

The plan is to have nearly all red energy suspension bushings and mounts on the Z71 soon.

Bought the springs today! They are alot beefier and have one heck of an over load. I was suprised to see that there are only 4 leafs and an over load. My Z71 has 4, they are thinner but still 4.
