Deaver +2 or Deaver +3 with Shackle?

I think you're confusing "droop" with "squat".

Droop is what you get when the truck is unloaded. For example, if you're offroading, and one of your tires is off the ground, the "droop" will allow the tire to essentially reach for the ground to try to make contact again.

Squat is how much the suspension compresses when you put a load on it. For example, when you put a load in the bed, it's how much your bumper gets closer to the ground.

Not knowing anything about the +2 vs +3 Deavers, I would GUESS that the spring rates are the same, so you would essentially get equal amounts of squat (given the same loads) between both options. However, the +3 with a longer shackle is going to allow for more droop than the +2.

Yes you are correct. And the spring rates are the same for +2 and +3.
Deaver does make a heavy duty rate but then when you are empty or not towing the ride would be terrible (more like a 3/4 ton)
Some guys that always have a bunch of gear in their bed (multiple tires, jack, etc) sometimes opt for +3 without long shackles or +4 with long shackles so it squats back to stock...OR just the normal +2/+3 long with heavy duty...really depends on how you attack offroad. Kinda like on a dirtbike when you just tighten up the stock spring vs increasing the rate. Ones going to be more plush while the latter you will have more (high speed) performance.

Thank you. Yes, I was confusing the two. That makes more sense.

We just received an entire pallet of Deaver springs. These have been backordered for months. If you want us set, give us a call or order online.

I did +4 with RPG 2 in drop shackle.


This was set up I did https://www.rpgoffroad.com/product/2017-gen-2-stage-3-rear-suspension-kit/

with

https://www.rpgoffroad.com/product/shackles-2/

Its a 1 in right height over stock since stock ford use a 1in block which comes when you install deavers.

i went +4hd with 2 in drop shackles. no sag in the rear loaded up.

Do the +4’s only come in HD?

Deavers:

Plus 2: Will duplicate the factory ride height with the factory 2" blocks removed.
Plus 3: Will be the same as above but just lift the rear aprox 1.0"
Plus 4: Will be same as above except lifting the rear 2.0"
All above basically same spring rates. Going to the "HD" on the Deaver part number still applies to above except the HD has a higher spring rate for towing/hauling.

Everything above is with a stock length shackle.
2.0" longer shackle: Will drop the rear end height aprox 1.0" no matter what spring set up you have from above. Two advantages are a more compliant ride and more droop..NOTE: You only get the droop if you run longer shocks thru the bed, the stock shocks are the droop limiter in stock form.

I run the Deaver +3 but with longer shackles so stock rear height...now Im going to Baja with 4 people and gear so installing a stock length shackle (Camburg) giving me about 1" increase in rear height. Empty the truck will taller then stock but looking at a set of front Geiser springs to level....

Awesome info!

I’m still in between +4s with a 2” longer shackle or +3s with stock length shackles... I have Fox 3.0 Factory Series in the rear.

I might do +4s to give me the option of raising it another inch if ever needed by swapping to a stock length shackle.

I watched a You Tube video where a gentleman stated if you're going to do springs the do the front first especially if you're hard core off roading as the other way around could cause damage to the front.

So that video is a little skewed I would bet. If your going to do "hard core" offroading then it all has to change. For the average off roader or weekend warrior that wants some extra out of an already capable truck, I can tell you my experience as I off road in my truck all the time. The first weak spot in the Raptor suspension is the stock rear leaf springs on 2" blocks. Anyone that drives a Raptor with stock rear leafs has felt the rear end "scoot" over on long sweeping turns on the freeway when you drive over an expansion joint. The first time it happened to me at 55 mph it scared the shit out of me. Off road you can feel the rear end dance over washboard roads. When I changed to Icon +3 leafs (which means they remove the 2" lift block and you get a 3" more arced leaf spring to remain stock height). So my rear end is up 1" over stock. It made the biggest difference in the truck, that I almost couldnt believe it. I then ran off road plenty on stock front shocks and quickly noticed the fronts are valved way to soft. I was diving hard under braking and mashing the front in ruts. I added the 2.25" RPG adjustable collars to the front to take out some pre-load and get the front up. Again it made a huge difference, the ride stiffened up only slightly, but it handled on and off road much better. In hind sight, the Geiser springs had just come out so didnt have that option then. I just recently purchased King 3.0's for the front so once they get installed next week, I will be able to tell the difference between collars on stock shocks and true aftermarket 3.0's with rezzys. So in a nutshell the rear spring should be the first change in your truck. It will make the most difference without any major upgrades or expense. The second most important to me is bump stops in the rear, too many bent frames without them. Thats just my humble opinion.

I agree 100%....almost every truck I've had the rear need help first.
In the Raptors case it's not just the spring rate and poor handling, it's the excessive axle wrap that comes with lift blocks...
