GEN 2 Deavers, Kings, and Sad Face

[Trick.Raptor]

@Trick.Raptor I will see if my local shop has a gauge. What would be an acceptable pressure range? or just let out 10% or so of current psi?

In my case 200 PSI. Some like 220 and 240. At 240 I was pretty stiff in the back with my chase rack and gear and I didn't like it. I think I tried 220 (I changed my notes... always write down what you are set it to keep track) after I found 200 PSI was working best for me so I don't fully remember.

If your Gen2 is empty most of the time you may want to go lower to 180 PSI. That is what Corey from RPG first suggested for my Gen1 as he likes a soft ride... I have yet to go that low with mine.

My 2018 has the SVC Bump kit (Fox 2.0 IFP) and the +3 Deavers (not HD) along with a 2" longer shackle, but factory shocks...My ride was different from factory, but not really stiffer..just a little less "float" and a more progressive spring rate as I get further into the wheel travel...I do not run the rear tires that high, I run mine at 31-32 psi and I do have a chase rack with 2 tires, ProEagle Jack and 10lb Powertank...Around town I run only about 34 psi in the fronts (except if I'm taking a trip out of town and all freeway, then get them to about 36 psi)

Up front I'd say spring rate, in back I'd say too much compression damping...And totally agree with the guys telling you to open up the compression tubes up front...

I'll try going down in psi some for the front and rear tires and see what difference that makes. I did open up the short compression tube in the rear bypass some and that helped. I guess the biggest difference I have with the new setup is that with certain bumps at low to medium speeds (20-45mph) the rear seems to bounce. It's hard to explain it, but its like a small tremor that kinda radiates into your head. I feel like a bobble head if that makes sense.

The compression adjuster is fully open in the front. I do have some additional preload in the front coil overs. If I'm correct, that doesn't effect the spring rate of the linear coil, but increases the potential energy, correct? that means that the coil will droop faster, but will still compress at the same rate? Maybe taking out some preload would help....

I understand that these are racing shocks, and will be firmer. They perform great off road. Especially when hauling ass. I guess I assumed that these shocks would be compliant on road at their most "open" settings, and then provide more dampening off road at their most "closed" settings.

I sometimes think it could be something as trivial as over torqued shackles.

Thanks for all of the input guys, it is definitely pushing me in the right direction.

My only complaint about the Kings on my ‘17 is the spring rate on the front is too high. I also run it wide open on the street and it’s still too much. Even Offroad I only go 2-3 clicks.

I wish they had a softer spring

Where can I find the torque specs?

Little update. So far, I have tried endless compression/rebound settings with little effect. Been riding around for the last week at 31-32 psi with about 450 lbs in the bed. Still very harsh. I'm pretty stumped... This week I'm going to take some preload out of the front coilovers and see if that helps. For the rear, I wonder if it could be something as trivial as the installers torquing the rear leafs/shackles before setting the vehicle down on its own weight. Maybe that caused some kind of preload in the rear? Who knows. May call around and see if Fox will sell some of their 550 lb/in springs that come on their factory race shocks. Thanks for all the input guys.

have you checked to make sure the rear shackles are in properly and arent contacting the frame?

Every shackle, even the factory ones, rubbed on my truck. I went with SVC's shackles and they dont rub a hair.


does it feel like the front is fighting the rear? like a bucking feeling? or just all around harsh?

Are you getting coil bind?

are you hitting your bumps at all?

are you making more that one change at a time? (i.e. adjusting multiple tubes at the same time)

I am running King 3.0s with +3 HD Deavers. My truck rides better than my new BMW M. It is slightly firmer than stock, but the dampening is ridiculous. My suspension eats up everything. I have put 10,000 miles on them.

But as you noted, you added race truck parts to your truck. There are only trade offs when it comes to adding aftermarket parts to your truck: do you want to sacrifice on road drive ability for off road ability?

Try 30psi up front and 26-28psi or so in the back for your tires. Have you had a chance to check the pressure on the Kings yet? I installed a Carli Pintop kit on my F450 and it rode way rougher than I thought it should. I called King and they said my shock pressure was probably too high. I checked it and they were at 220psi. They suggested I not go down below 100psi or so, so I put it down to 110psi and it made a world of difference. Gone was the harsh banging I got across freeway expansion joints, etc. King said that if lowering the shock pressure didn't help then they would revalve them for me based on my preferences. Apparently the first revalve is free, so all you would have to do is pay shipping back and forth. I'm guessing a change in your shock pressure will make quite a bit of difference.

There doesn't look to be any interference between the shackle and the frame, but i will double check both sides this afternoon.

I guess you could say there is a bucking sensation. It feels as though the rear is preloaded; every bump I go over is much more abrupt in the rear. Maybe this causes the front to feel stiffer than it is?

How could I check for coil bind?

The rear bumps have plenty of clearance. Only engage them when I'm running the truck hard off road.

I have been taking detailed notes of any adjustments made to the rear bypasses. Only adjusting one tube at a time; usually in increments of 1 - 1.5 revolutions.
