dont think they are on crew cabs. ext cabs and reg cabs maybe because of the 1 piece driveshaft. crew cabs have 2-piece shafts with a carrier bearing to achieve the right angle...

Re: F350 4" blocks tepered or not?

Re: F350 4" blocks tepered or not?

I read on this site that you should replace tapered with tapered, and non with non.

I replaced my non tapered blocks (crew cab) with non tapered and experienced no vibration problems.

Re: F350 4" blocks tepered or not?

I bought the blocks from my local suspension shop along with the new U-Bolts. I found out that you have to shim the carrier bearing. I don't know how much I have to shim yet but I have been told about an inch. Not a big deal. U-bolts and new shims ran me $100.

if youve got a 2 piece driveshaft(crew cabs), youre better off with a flat block...
