My PMF rsk comes in this week.
Theres enough of these out there , I'm sure, somebody knows,
what size blocks I should get? Tapered or non-tapered?
I cant do shackle flip, my 3" exhaust is in the way.
Currently rear is stock f250, so it will look goofy if not raised up in rear.
I'm guessing 5"?

Thanks
Jim

 

What size RSK did you order? Did you install it yet? What size tires are you running? Did you do anything to the rear?

 

Stock F350 uses a 5" rear block so you could just order some stock blocks from Ford or find some in a junk yard. be sure to get new U-Bolts.

Diesel Rod

 

Stock F350 uses a 4" block. and that would make the truck sit perfectly level

 

I bought 5"blocks, sits level.
The PMF kit is a breeze to put in.
Ride is really nice now.
Fitment and welding couldn't possibly be better.
Drill out front spring eyes and you pay half the price for eye bolts,
If they dont come with your springs.

 

Nope. 4". TRust me. I have worked on more F350s than most people have even seen

 

Maybe the x spring code, made mine 5" .
All the wheel wells measure the same .
Installed front first, then measured for blocks.
Maybe older droopy rear springs, I dont know!
Looks good anyway nice and even.

 

Did you install the 2.25" or 3.5" kit? Stock rear springs with a 5" block?

 

Yes, X codes will make the front sit higher. They are the HIGHEST rated front spring offered from ford. But give it a month and let things settle in

 

I installed 2.25 kit. X code springs. 5" block.
Sits level. If it drops an inch in a month, I, m ok with it.
Brad is usually right, thats why any questions should go to him , he, s done a few.
