1" Rear Block

I have a 2020 F350 CCLB with a Carli 3.5" Pintop system with the Full replacement rear Deaver spring packs. This eliminates the factory blocks completely, the leaf's sit right in the perch.

I want to add a 1" block to the rear. Has anyone seen a good 1" block for sale? Do I want tapered? Flat?

Thanks in advance!

my 2019 f-450 had a 1" block. flat. but, the pin and the pin holes was larger than SRW blocks.

PMS fabrication can make blocks but I think they start at 1.5"

Maybe look into the leaf spring shims that One Up Offroad sells. The have several different thicknesses up to 3/4" I believe they can be stacked to achieve your desired ride height.

Did you remove the block in your 450? Are you running no block. Thanks

I replaced the 1” block with a 5” block.

Jay,

1-inch available from

https://www.pmfsuspension.com/2017-2...cks_p_173.html

I think they can talk you through whether a taper would be good with your setup..

I have the 1.5" PMF blocks on my CCLB 250. PMF told me that for the long bed, no taper for the 1.5", even though the factory 3" was tapered slightly.

The taper question is definitely confusing


factors are 2 piece drive shaft or 1

and

carrier drop bearing spacer or not

so, my understanding ,

for 2 piece it’s tapered or not tapered plus a carrier bearing spacer

for 1 piece drive shaft, it’s not tapered

and as stated above the DRW ubolts and bolt holes are bigger than SRW . On PMF website they ask about DRW or not
