I have asked this before but here goes again. Any issues with the pinion angle using the procomp 5.5" Blocks, axle wrap etc??? Are they tapered??? I have a 06 4x4....

 

i have been running them for almost a month now. they are not tapered and i have not had any problems yet.

 

Yea Ive been running them for over a year now and not one problem. I would suggest them instead of stacking blocks.

 

Lift blocks for f-150s can't be tapered because there are 2 center pin bolts going through the leaf spring pack instead of the usual 1 on other vehicles. If the block was tapered, the heads of the center pin bolts wouldn't line up correctly with the corresponding holes in the top of the blocks.

And I agree, don't stack blocks if you can avoid it. It's just another variable that can cause problems. And it could be a pretty serious problem if the blocks separated while you were driving

 

Actually they are tapered slightly. the dual pins do not matter as it is still a flat surface where it meets the axle and leaf assembly. I was mainly worried about axle wrap...I am just not used to running such a large block. I really don't want to spend the money for the custom leafs. I ordered the blocks yesterday. I also agree with not stacking them. I already ditched the little block that came with the procomp kit as well as the stock little 2" block.

 

can you find any info that says the pro comp 5.5" blocks are tapered. cause i am pretty sure they are not tapered.

 

I doubt they are. My 5" Fabtech blocks are not tapered

 

I spoke with the rep from Pro-comp directly, not 4wheelparts and he said that the block is tapered about 1/8" overall. Not much at all but that is what I am being told. I will measure and post when they get here but that is what the rep said....

 

The fabtech blocks are not tapered, you are correct, I installed helped install that kit on my neighbors truck, they measure the same front and back. I am not trying to get into a pissing contest believe me, just relaying what I am being told about the procomp blocks. I will post my findings when they arrive...

 

I believe you. I've never thoroughly researched the procomp lift

They are tapered...

 

Yeah they are. I wish I had those blocks. I need another half inch or inch in the back to be level. I'm bulldogging slightly now with a 5 inch block.

 

i have the pro comp 5.5" blocks with the bump stop built in, different from the ones you linked. i dont think mine are tapered.

 

Very nice truck though...I was going to buy those tires. I here they are great offroad but do not really have that great of road manners...What do you think???

 

I thought they wouldn't be that great on the road, but they are fine. They have pretty loud tire roar, but I like it. They don't pull or shake or anything. I'm pretty impressed by their road manners.
