What can you tell me about Iron Rock Off Roads shackle? I am looking at that plus the front spacer. I am running 235/75 15 tires and plan to get 30X9.5 and be done. It is a work vehicle and daily driver.

I will be replacing the springs with Quadratec Heavy Duty Springs soon so I figured shackle would be a good idea over the add a leaf. Opinions?

In my opinion your looking into a block of rubber for the front and a block of steel for the back with new ubolts....

I'd go with the best price, probably not much difference between quality of budget boosts.

just get the tera flex budget boost. they are one of the few the provide a full guessetedd rear shackle and is greasable. i still use mine today.
