leveling kit with 6500lb springs 07 f350

This forum is very helpful, to start off with! I have a 07 f350 single cab flatbed dually 6.0 4x4. Bought it few months ago, customizing the flatbed and I have been unhappy with how the front end looks. I installed a 2" top coil spring leveling kit few days after I bought truck and made it look better, but not level. After reading this forum, I found out I have 5200lb springs. Right now I sit about same height as similar f350s with 6000lb springs. My bigges question is can I buy and install 6500lb springs along with the top 2" leveling kit without installing drop radius brackets? I also have another 2" leveling kit, but it mounts under the coil spring. Could I use both leveling kits to achieve the look I want, without radius drop brackets or would I be better with 6500lb springs and leveling kit. Thanks for all your help in advance.

I don't own a 6.0, and don't have any experience with coils.. But here's my two cents from a fairly mechanically inclined mind..

You already did a "leveling" kit, you're still within the max factory specs, the same as if you installed the 6500lb springs like you mentioned.

Assume the stiffer springs bring you up another 2-2.5"... that's a " 4" " lift in front... add the second leveling kit (not a smart idea.. especially when spacers are involved)
and you'll have " 6" " of lift up front..

Look up quality lift kits (not ebay junk) and see what they include. If it's in the parts list it's there for a reason.

My bet is you'll need to relocate your radius arms @ " 4" " of lift. I have 4000lb leafs under the front of my '00 (3" lift) and I am suffering serious bump steer, something else you need to consider when adding 4" of lift...

Don't cobble together parts, buy a kit that is engineered to function properly together, those guys get paid big money to make sure it works right.

Hope this helps,

I don't think the OEM 6500lb springs will be taller overall. The spring rate is higher if anything. Don't use the additional 2" leveling kit, just swap in the springs. Any more height and you will need more components to fix the steering geometry.

I ordered 6000lb instead of 6500lb springs and longer Rancho shocks. I plan to swap springs this weekend. Only issue I see now is not being able to align truck due to needing radius drop brackets and/or needing drop pitman arm. The springs are same height as of the 5200, but like you said spring rate is higher, so it would sit higher. I hope to acheive overall of 3.5"-4" by just using oem springs and a leveling kit.

You might need an adjustable track bar with that amount of lift.

I installed the 6000lb springs and new Rancho shocks. Rides better, but I may have got 1" of lift. Very disappointing since everyone has same springs and sits taller. Where the track bar bolts to frame, I spaced the bolts which centered axle with truck. I did the 6000lb springs with a 2" top leveling kit with 265/70/17 tires, its measures 41.5" from ground to center of fender wheel.
