F-550 Front Coils in F-350

**matt1030** · #1 (**permalink**) 01-20-2013, 09:30 AM

I was wondering if anyone has put the 7000# springs into a F-350 with the 6.7 Diesel? I run a 9' Fisher Plow and I don't like the sag I'm getting. I also don't want to do spacers. I found a set of Firestone airbags that go inside the coil as another option. Ignore my signature I recently bought a 2012 F-350 Lariat to replace my 2007. Thanks for any help.

I have them on my 2006, though I dont plow. They are great. About $90 each from Ford. Takes about 1 hour to change them. You will be glad you did it. Stiffens the front end as well (feels less squirly, and I have had no hint of death wobble since).

Personally I would skip the air bags. I started with 5,200LB coils, then went to 6,000LB coils (snow plow prep), and then went to 7,000LB coils. They are perfect for our truck camper!

I eventually plan to put the 550 coils in my 08-350 to level it up without using one of those cheesy leveling kits.

That's interesting will this work for an 06 f350 I want to level but don't want to use the stupid puck spacers.

I don't see why it wouldn't work, the suspension is relatively unchanged from 05-10

The 7000LB coils will level a F250. An F350 SRW will still be high in the rear, so you would also need a 1" spacer to go under the coils (e.g., ICON TEI spacer).
