Greetings,

Just wondering if I could get another opinion on swapping out the rear blocks in my 01 F250 and replacing them with F350 blocks. Im thinking of just doing the blocks rather than doing both the blocks and springs. Im basically just looking to get rid of a little of the sag in the rear end. My train of though it that I dont do a lot of heavy towing so I am thinking the 350 springs would be worthless in my application.

Like I said I'm open to any ideas and/or opinions. Also correct me if I am wrong the 250 blocks are 4 inches and the 350 blocks are either 5 or 5.5 correct?

Thanks again,

Adam

 

Some F250s have the exact same blocks and spring pack as the F350 (SRW) trucks. So it's not really a F250 or F350 thing...it's more like a tall block vs short block thing, both of which can be found on F250 trucks.

I assume that you have the smaller block (which is 2" tall I think...). If you are looking for the taller block (4") than you will need the u-bolts as well, which also means you'll need the helper spring just so you don't run out of threads on the bolts. If you are looking for a softer ride then you can run lower air pressure or D rated tires. Personally, I don't like the steering feel with D rated tires but it's your choice...

You can run the 350 blocks with longer u-bolts on your suspension without adding or removing any springs for your desired hight, thats what I did thanks to (Spdmpo) Keith here hooking me up with his. Mine was just about an inch lower in the back after adding a shackle kit in the front. It looked good leveled but when I towed it dropped in the back hence the 350 upgrade.

 

I had two extra springs added to the front end on each side. Which gave me 3" of lift on the front. I needed the F-350 blocks on mine to level it. They call them 3.75' blocks or something like that. It made mine level out perfectly.

 

Airbags I just put firestone ride rite bags in 250 bucks. Made the ride nice and soft when Im not plowing. Air them up to 70 psi when the plow is on work great and east to install.

 

Thats the impression I got when doing some shopping online. Thanks everyone for your responses. I am going to go out and check and see if I can see how big the blocks that are on it now are and go from there.
