I was doing a break job this weekend and noticed spacer blocks on my rear axle. The guy I bought the truck from didn't say anything about it being lifted. It has a 3.5" block on the rear axle. Is that stock or was it lifted?

I replaced my shocks last year with stock shocks and it doesn't tow real good, seems to wander/sway. I just replaced my steering box with a Red Head unit. It seems better but still feels like it is on real low pressure tires, swaying if you turn suddenly. I had my front end aligned and everything was checked they said. So now I am wondering if maybe the truck was lifted and my shocks are the wrong ones for it and helping on the swaying issue.

Thoughts?

 

Looks aftermarket to me. I dont think Ford would make a block that hollow

 

3.5" would be equivalent to the F350 blocks though.

If you want the proper Ford blocks check out the link below. Keep in mind depending on wheel base uses tapered or flat blocks. All in the thread.

Early 99 250's (like mine) had the tall 350-sized blocks, later 99 250's had the shorter blocks.
