2020+ OE 2" Blocks

Hey everyone, just joined the forum. It's been a wealth of knowledge so far, thank you.

I'd like to do a reverse level on my 2017 F250 CCSB by removing the factory 3.25" rear blocks in favor of some 2" factory blocks. I looked at the PMF blocks and while they're very high quality, I'd prefer not to spend too much on this project and use Ford parts if I can.

I know I can use the non-tapered 2011-2016 2" rear blocks (6C3Z-5598-A) and associated u-bolts. However, since my truck came with tapered blocks, I'd like to replace them with tapered blocks. Based on my research, 2020-2023 rear blocks are 2" and tapered.

See the following thread: https://www.ford-trucks.com/forums/1...2020-f350.html

Can anyone confirm this for me?

Also, if any of you have a set of 2020+ 2" rear blocks you no longer have any use for, I'd be interested in purchasing them. Not sure if I'm cleared to use the classifieds yet since I'm a brand new member and this is my first post.

Out of curiosity, why lower the rear? It is effectively lowering your hauling capability as you're bringing the axle closer to the bump stops, which you don't really want to ride on. Think of it as going from a somewhat decent ride to a sharp, jarring slam every time you hit a bump.

I'd much rather raise the front if I were going to level something, at least you aren't going to hit/ride on your bump stops as easily.

I'm pretty sure that the bump stop tang is also lower with the shorter block. So the distance before bump stop contact should remain the same. It's essentially just lowering the rear the same as a 2020+ SD.

I too would prefer to bring the front up, only because the front has such little travel before bump stop contact.

I've already lifted the front 1.5", but the rear is still 2.5" higher than the front. I can't lift the front anymore at this time because my family also uses the vehicle. By taking the 3.25" block out and replacing it with a 2" I'll be within about 1.25-1.5" of level front to rear which is right where I'd like to be.

As noted in the previous post, the bump stop on the 2020+ 2" block is lower so there will be no loss in suspension travel.

Just a couple info points that might be useful.

My 2020 CCLB came with 2" non-tapered blocks, perhaps the short box trucks have tapered?

And yes the bumpstop distance to the axle wont change.

The only consideration you might want to think about is having your headlights adjusted.

That means you were 4" higher in the rear when stock? That is a lot, and more than most I would think. That is a full 1" more rake than my 2019 has.

If someone with a 2020 or newer Crew Cab short bed could slide under their truck and measure their rear block that would be super helpful. I looked under a few newer Super Duties the other day in a public parking lot and can see they have 2" blocks. However, I did not have a measuring tape to see what the height difference between the front and rear of the block were.

Anybody have a set of take-off 2" 2020 or newer blocks they're willing to part with cheap?

Truck details in sig.

Front of the block 2”



Rear of the block 2”



And just because I was already there, about 4-1/2” between bump stops

Thank you for those very helpful pictures!

I am trying to figure out what the Ford p/n are for these blocks. I called a local dealership yesterday, but they needed the last 8 digits of a VIN to look it up since there were multiple p/n listed for that component.

Anyone with a 2020+ CCSB F250 have tapered 2" blocks?

that’s super high

my 19 had 1” blocks stock on 31” wheels and now is +4 (5 inch block) with 37 tires and I have a gap that could easily pass a foot ball.

The VIN is generally included with vehicles that are for sale. I used the VIN from a 2021 4x4 F-250 CCSB and came up with 4 part #'s. Two were for 20-23 "less attitude", and two were for 20-22.

The 20-22 part #'s are LC3Z-559, LC3Z-5598C. RH,LH.
Not sure what the problem is, but the last 2 digits of that part # turn into that emoji. It is an 8 and a D.

yeah I’m not sure how it won’t be nose high if this guys raises the front 1.5 then lowers the back 1.25.

That’s already an elimination of 2.75” of rake and says he’d still have over an inch rake?

hard to believe any super duty came with 4” or more rake to make that possible but maybe it is…

Poor access of the bed of these trucks is why they added bed steps

Thank you sir! That's also what I came up with. The other two P/N were LC3Z-5598-A and LC3Z-5598-B. (LH/RH).

I'll see if I can place a WTB add in the classifieds here and try to find someone who has a set of take-offs they're willing to sell.
