Alternate rear spring options?

[Grayson]

The only limit to coil springs vs leaf springs is location on the axle. Coil Spring Specialities can make a custom set of springs for you without breaking the bank

Has anyone found rear coil upgrades for static load increase of approx 350#?

Are you a 35 or 37?

I might be the only one in the world but I have a diesel aux tank in the back of my gen 3 to fill up my skid steers on Jobsites. Came from a f450 king ranch. Do I miss my 450?….yes but the raptor is really fun to drive and the suspension / handling and acceleration are great. Just think I’m a super duty guy but I’ll enjoy the heck out of this raptor till I get a 23 super duty.

Loaded it’s about 1000 pounds. I have 35 package. I put RPG 2” spacers in back and when loaded it’s now level. When I’m low on fuel it raises about 1.5 inches with a nice little rake but not crazy. It’s perfect. And it still rides like a champ.

I probably will wait til sometime comes out to sustain 1000 pounds without lowering then put a 1.5” rpg on front then go 37’s but for now it’s perfect

Is anyone running a GFC and decked/similar drawer system. I’m guessing spacers/ upgraded rear coils would be needed.

I built a sliding kitchen ... it is about 300 pounds, in order to support the extra load, added both 3/4" spacer and airlift airbags (15 PSI), and it works perfect for me, for sure once I will be able to lift springs with 250+ I will do. btw I also calibrate the new high using forscan

Do you know what the part number is for your air bag kit?

sure, I tried 2 kits until I found the perfect one for me, in airlift you have a calculator that you can provide dimensions and get part#, but anyway I'm using the biggest they producing...
it is part #60927
https://www.amazon.com/dp/B018O94ZK4/?tag=fordraptorforum-20, install it with all spacers they come with (2 per side)
