Hello i have a 1994 ford f150. I want to lift my truck 4 inches and have the stage 2 kit with blocks from procomp. I was wondering when installing the blocks in the rear, do i remove this bump stop (not sure if that is exactly what it is) and then put the block on the axle. Is it ok to remove that? I heard you should never stack anything. so should i not put one on the other. Just a newbie at these kinds of things so not sure if my questions are dumb or not. Thanks in advance. ps. Ive added pictures of what i believe to be the bump stops.

yea its fine, all the bumpstop does is limit the travel your truck can go. if you do end up stacking blocks you need to weld the 2 together so they act as one. this helps reduce the chance of spitting them out and breaking bolts and lots of other stuff. also when going that high with blocks you will need some sort of ladder bar or your axlewrap will be so bad you will bust a driveshaft time and time again

Sounds like my best bet is removing the bump stops and just replacing them with blocks.

 

you said you had a way to get a pic of what you are talking about, right? if so post it up so that we are clear on what you are talking about!

I took out the bumpstop and put in an add-a-leaf and used the block that came in my lift. They said to stack the blocks but from advise I got here and just stopping and thinking about it for a second, I came to the conclusion I did not like that idea. I went with pro-comp add-a-leafs (long ones) and they gave me 2" of lift, which is the height of the bumpstop. I am happy with the set-up.

 

This would be one of the better ways to go.

Just so I'm on the same page, what your calling bumpstops are the original factory blocks right?

The other way to go about this would be to do a shackle flip, which would get you 3" of lift, or like bchunter said, add a leafs.
Sacked blocks = bad

 

Yes, that is correct.

 

We did the same thing on a buddy's 95 F150. He also wanted a stiffer leaf pack, so this eliminated the stacking blocks and got some lift.

Personally, I think that up to a 4" lift block is ok as long as it is a primarily street vehicle with open diffs and all terrains. Lockers and agressive tires can really create axle wrap with blocks offroad. That's why I ditched mine altogether.

 

yeah mabye ill look at getting add-a-leafs from procomp. thanks for the advice.
