Not sitting level after King shocks installed

[ScumbagTakumi]

Just looks like you need more spring which is a cheap and relatively easy fix.

Well, King did respond back and they indicated they had not seen this issue for the Bronco yet. I assume they will get back to me on which springs to buy and replace. I think the total weight of my "stuff" in the rear is about 100 lbs. I would just think the factory setting would have easily handle 100 lbs back there. Later today, I am going to remove the fridge and the drawers to see what the results will be. FYI the top spring is SPR 3-4-500 E22 and the bottom is SPR 3-14-350 E22. Looking at the King spring catalog, the top spring is the only one they offer, for the lower spring they offer every rate from 150lb to 700lb in 50lb increments.

King private labels most if not all of their springs from Eibach and they have a of springs in a 3" ID and with a 4" free length like you need. They will be silver but You can definitely get the rate you are looking for. I would presume a 600 lb spring would probably work well but it does look like they have heavier rates as well https://eibach.com/us/i-619-eibach-silver-coilover-spring-3-00-i-d.html

That is the correct fix

Any updates on what you did
I just ordered the eibach upper spring.
And going to install that.

Well, I didn't think all the stuff in the rear would have caused it to drop that much considering I didn't really see any dip in the rear with the sasquatch suspension installed. I did send King an email asking them about it but I think you both may be correct that I will need to install stiffer springs. I will see what King tells me. I may try removing everything from the rear and see what it does. I appreciate everyone's feedback.

I changed to coil overs and use the Ford drawer in the rear of my bronco. I have a fair amount of stuff in it but not as much as you. Even with what I have, the rear of my bronco sits lower than the front. I had to add an additional inch and a half of lift to the rear coil overs to level the truck. I didn’t think the amount of weight would make such a big difference and sag the vehicle so much but it did.

So, I decided to talk with Down South Motorsports who I bought the Kings from. They are really knowledgeable with offroad suspensions. They explained to me that the top spring really is a tender spring. And changing out that spring will really not help. They recommended going with a larger main spring. I just purchased the 450lb spring. He said that you want to size the main spring to handle any additional loading to the rear and then just use the top tender spring to create your preload as needed. So, once I get those delivered and installed, I will let you know.

I guess with you going with the top spring change, let's see which creates a better solution to the issue. Let me know your results once you get them installed.

Trust me, I was surprised as well. I knew it would sag some but not as bad as it did. With the factory Sasquatch Bilstein shocks, I did not have any real sag in the rear. But with the King coilovers, it sagged way more than I thought. I ordered and will be swapping out the main 350lb springs with 450lb and see if that gets me to a more leveled stance.

I might still consider stepping up the secondary spring as well especially since that is what is eating up your preload. It is basically your "bump spring" or the stiffer rate for when the suspension is about to bottom out so it may work better to have a 600 lb secondary with the 450 lb main spring.

I have it cranked down where the top spring is fully compressed. I will definitely need a heavier spring. Waiting on a recommendation from King.

Are you going to install a larger tire soon? Why so much fender clearance now? Are the Front Coil Overs maxed out as well?

I'd lower the Front Coils One and a half inches or so, then lower the rear about an inch. It looks like you have plenty of height front and rear to work with and adjust up and down.

The fronts are set as King sets them from the factory. I will eventually be swapping out to 37's so I will need the space. I have heavier rear springs sitting in my garage and will hopefully be installing those this week.

 

[Aztec1382]

Changed out to the 450 lower
And you are definitely going to want to go higher with the weight you are carrying.

It just further compresses the top spring

definitely going to have to install the eibach 600 lbs tender

I actually just finished changing out the 350 for the 450 like 1 hour ago. It is sitting level right now with the preload set at just about 1 inch. I didn't get any pics of the shocks with it sitting on the ground but it is now sitting almost dead level with everything I typically carry in the back. I can tell you that the top spring in almost completely compressed. Based on a response from King and another shock specialist, it is not a big deal if that top spring is compressed this way. They indicated that the main spring is what you really want to set your load weight with.

For folks saying the front or back is a different height than the other end, use a tape measure and provide the measurements. Photos for lots of reasons don't work.

i ended up with 1 inch of preload as well
However i think once the suspension settles you will realize you need a heavier top spring.

I may eventually go with a heaver top spring but I am not in the mood to tear everything out again. Maybe later next year when I am feeling bored!

How much weight do you have in the rear of your vehicle? I would also be interested to see what the rear springs look like on a Bronco with no additional weight and set to King factory settings? Wonder what the top spring looks like.
