What makes a 350 taller than a 250?

[jimmyv13]

I have a few buddy's with 350's and they are all around 2" taller than mine. I asked them what the difference was between our trucks and nobody knew...one guy thought the suspension was different. We all have stock wheels, tires, and no lifts or level kits.

Anybody know what makes a 350 taller than a 250 in stock form?

the f250 has a 2in rear block between the axle and the leaf springs. While the f350 has a 4in rear block between the axle and the leaf springs.

Correct. Different GVWR ratings also have different effects. For example I have a 250 but I have the same payload rating as an SRW 350/.

Is it as easy as finding the 4" blocks and longer U bolts and bolting them in?

What about the front? Billstein 5100's?

if you are trying to level your truck. i think you need to get the 4in rear blocks with the longer u bolts. and i think you would need bigger coils in the front and longer shocks all the way around but im not sure.

[jimmyv13]

Yeah, I'm considering leveling it. The suspension has to be tired as there's over 200K on the truck and the rusty Rancho shocks up front probably need replacing. I was thinking about getting new shocks up front and a level kit, but then thought that the front may be higher than the back. I'd like to get 35's under the truck.

If you want to be the same height as a 250 get the 4 inch block and Ubolts for the rear and the shocks. Get a leveling kit for the front if you want.

The front of the 250 and the 350 are the same height from the factory unless one has a plow package and one doesnt.

Would I run my VIN to see if it has a plow package?
