Do you need to run a larger block on your rear suspension so the raptor shocks won't bottom out or do they bolt directly up?

gDMJoe

They are direct bolt-ons will no need for modification.

You must run Raptor 2.5" rear blocks to compensate for additional shock length

I keep researching all over the Internet and I keep hearing it both ways. I will probably end up doing a rear block. I'm thinking lifting the front with blisten 5100s. Will this set up be good together? Then eventually k02 275/60/20 tires. What do you guys think?

I have them on my truck..... LOVE Them!
I used a 2" rear block without any issues. It will not work well with the stock blocks however.

I will be changing to the F150Lifts.com 2.5" "Raptor Style" rear blocks in a few weeks when I put on the 3" Coil overs.....keeping the Fox Rear shocks.

I have a frint level and I added a 1" rear block. I got the block kit free. I have a friend getting rid of these shocks. I have first crack at them. with the setup I have I wont have any issues?

UIN2IT

Depends...you added a 1" rear block ONTOP of the stock 1.25" block? (I don't recommend that!)

If you have at least a 2" total block in the rear you will be fine with the Fox Shocks from the Raptor.
However, 2.5" is recommended.

So I put the raptor shocks on the back but I didn't put the bigger block, left the stock fx4 block. So far no issues but what is the concern not having the 2.5" block?

fx4mikeo

I would like to know the same. How long have you been running the raptor shocks with the stock block?

Bottoming out the shock on compression since there is less room for up travel. If you don't take the truck offroad it may not be an issue.
