Deaver +3HD vs +4HD (Confused after all the researching)

[Winchester30]

2018 w/ stock front suspension.
I have a leer cap on the back +150lbs in back. I went with +3HDs and have noticeable rake in the rear.
+4 would have been too much for me personally but everything else is stock.
Happy with the Deavers overall.
Get yourself a high speed cutting wheel to remove the two bolts.

I went with Deavers +3 HD, Camburg lowering shackles and carry between the tonneau cover and field tools, etc., about 250 lbs in the rear. The front has a winch and winch bumper (the bumper is aluminum so only adds +40 lbs over stock, winch adds about +120). I lost about a inch in the front, but even with the lowering shackles, the rear is still higher than before i swapped in the deavers.
My next step is to go with probably new Gieser +2.5"front springs (probably only lift about 1.5" above stock, the other 1" will be to recover weight of winch, etc.). I will re-evaluate rake then, may swap out to standard length shackles then-i tow a toy hauler, so don't want to be nose high.

Hi all, this forum has an abundant amount of information, and there may be answers out there already for this, but I've ultimately gotten more confused reading and asking around while shopping for price.

I have reached out to Apollo Optics, SVC, and Texas Motorwerx. Though they provided very insightful responses, I got mixed answers. So before spending the money and realizing I made a mistake thought I would get one more opinion from here.

I have a recently acquired 2019 raptor screw with close to 35k miles and the rear leaf springs are flat. The truck is barely level as of now. I carry 350lbs constant weight all the time. When I camp/offroad I will carry an additional 200lbs easily with an RTT/gear/etc. I like the stock ride, but I want to get a little bit of rake (I don't want to be nose high).

For the rear, this is what I've been suggested:

+3HD because +4HD is for mid-travel trucks.
+4HD will settle to about 1.5" above stock with my static weight.
+4HD w/ Eibach upfront and drop shackles if needed.

For the bumps:

Camburg w/2.5 Fox b/c 2.0 IFP may not be the best for our heavy trucks.
SVC w/2.0 Fox IFP.

Also adding within the next month, if this suggests I should do something with the front:
Winch, bumper, and FMIC to the front.

What's everyone's suggestion? I'm leaning towards the +4HD and SVC Kit w/2.0 Fox IFP.

I'm hoping this will give me a slight rake with 350lbs in the bed and then level when fully loaded for camping. Once I add the stuff to the front, and if it drops the front too much I can get the Eibach springs until I can afford the Fox Racing 3.0.

I appreciate everyone's contribution to this forum and all the vendors I reached out to! Thanks in advance.

I think you need to figure out first what your going to do in front. Work with a reputable suspension shop specializing in raptors. Front end mods are tricky at best. If you mess with the geometry your asking for trouble down the road as it will change the wear points on front end parts. Collars just pre load the springs and new springs change the geometry. Your suspension expert will have the deets on the best approach. Once you know how your going to address the front then the rear comes into play. The stock raptor springs are a two stage spring. The packaged Deaver +3 +4 packs are all progressive. Deaver told me that their pre packaged springs are not recommended for towing if that's your thing. Not that you cant but they didn't reccomend it...at least based on my use case. Call Deaver or Icon directly and speak with a tech about your individual use case and what they suggest. For me they steered me away from their pre packaged sets and gave me a custom solution that was actually cheaper and retained the two stage characteristics of the stock spring. One size does not fit all and you are smart to take it slow. Work with your raptor specialized suspension shop and Deaver/icon directly to get your answers and make sure you are describing your use case thoroughly.

L84HD Is 1" Higher then stock $ HD designed for 500lbs bed weight.
That is the most common.
If you go with the +4hd and run adjustable front shocks, you can fine tune the ride height / Add longer shackles to lower it.

For rear bumps. you should be looking at 2.5" not 2.0s

This is a stock truck with +4HD with SVC collars

That truck looks just like the one in my garage. ;-).

I believe my stock rear springs were worn out and sagging so was much lower than normal.

Here are the before/after measurements to the highest point of the bottom side of fender flares on passenger side.

Front 39 3/4 to 42 1/8
Rear 40 1/4 to 44 1/8

If it doesn't settle to about 42-42 1/2 in the rear after I tow and add my gear. I will do drop shackles.

Hope that helps.

Btw, Jeff is that guy that knows a ton about these suspensions.

I have basically the same use case. 200 on the daily and 550 ish lbs on 'overlanding' trips. I think you'll find the +4 HD too high without shackles that's for sure. From what I've seen, they don't settle much.

I think your short and longer term plan for the front will dictate your decision. Like me - planning to pull the trigger on the Fox Race Series 3's, I think I'll do Icons on stage 3 or Deavers +3HD and keep the FRS 3.s at maybe 1" of lift instead of 2. Better action on the front, a bit more clearance which would be nice, and better load capacity and a bit of rake which I don't mind.

Thanks for the reply!

Are those numbers running +4HD and something like Eibach's in the front?

Yeah, that is actually exactly my scenario as well. However, I am not planning on pulling the trigger for the new Fox shocks right away but rather want to do the Eibach in the meantime.

I guess I'm just looking for photos of a truck with the Eibach and Deaver +3HD or +4HD carrying an "overland" type of load. It's a lot of money and it's scary to have to redo lol

Do you think that with the Eibach and +3HD the truck will sit with a slight rake?

I'll have the winch/bumper on within the next few months as well so I'm assuming mine will sag the front down the same as yours.

I was going to do geisers up front for some extra ground clearance (approach angle) and to better match the icons on the back. The more I've thought about it, the more I am just going to go straight to the race series 3's and be done with it. It might be overkill for a lot of what I do, but I generally like to run my gear within design spec and not at the edge of its envelope. Lasts a lot longer and for the times when you need the extra capacity/capability, you have it at your disposal.

There might be better higher performance options, but the race series use the stock live valve's and have some adjustability for my varied demands without needing constant farting around.

This setup is +4HD (M44) deavers and SVC collars up front. Rebuilt shocks from Forged Offroad. Maybe some day I'll buy new coilovers and rear shocks.

I went with +4HD cause I tow (6500lbs camper) and will have overlanding gear (no tent)/tools in the bed. Easy to drop with shackles if it doesn't settle where I want it, very expensive to go higher with only +3's. Plus +3's where months out. +4's where in stock.

When first picked it up, it was way too high. After a week of driving it around it is growing on me. Hit very light 2wd dirt roads yesterday and it rides great! Next weekend will be the test.
