Bumper/winch Front End Sag- How to fix.

[andersman02]

Big Bend SaS


After added a Fab Fours stubby and Winch- I got an additional .5-.75" front sag. Total rake now is about 1.5". I'd like to raise up the front to be at about .5-.75"rake, and also bring the back up a bit, maybe an inch. That would essentially mean bringing the front up ~2" and Back ~1" from where it sits now.

My options I'm looking into
-Eibach Spring Replacements
-Billstein 6100's w/ SaS springs
-Rpg 2.25"/1" perch collar.

I currently like the ride as it is, just not necessarily the rake. I think all 3 of these would get me the lift, however the Eibach springs have been said to have a fair amount of dive, expecially with the heavier front end.

The Billsteins I also like, however the SaS billsteins are great andI'd be kinda sad to see them go.

The Perch collar seems like a good fit too, as I BELIEVE, that amount of perch may actually put the factory billsteins more into their best position for day to day driving.

I do use this off pavement, Rocks/ forest roads/ etc. Have and continue to plan on doing 1-2Jeep Badge trips each year ranking from 4-7 difficulty

Thoughts?

If you want to keep the same ride, the 5100, 6100 or even a perch collar should work, just keep in mind you have an extra 100-150 lbs of weight on top of those stock springs so it could be a bit soft or wallowy.

I would also look into Old Man Emu medium springs which should be rated for the additional weight.

I recommend 1.25 perch collars from wildhorses4x4. com. I had them and really miss the firmness they added with my heavy bumper and winch. I now have eibach springs and although I like the added height and nice ride they gave I absolutely hate the brake dive and body sway now. They suck compared to the ride quality that I had with the 1.25 perch collars and sasquatch springs.

To use Old Man Emu springs you need to use their struts or you’ll need to remove the rubber isolator on the bottom of a Sasquatch strut so they’ll seat properly on the bottom perch.

Get some spring wedges. Cheap easy install that should get your .75-1” back.

I know you didn't have this on your list but I used a 1" RC leveling kit to level my Bronco back out after I added my winch. Ended up looking just right and didn't change the feel really much at all. Cost and ease of installation was great too.

I will say I always knew it was going to be temporary until I upgraded coil-overs. I went with Eibach 2.0s and I really like them.

You could remove the winch since you never use it anyway?

It does get used, and no way I'm doing some of the Types of trails Ihave done without one. I probably used it more than most people, not directly off road related...

Stiffer springs.

Well then great idea, also go ahead and remove the air bags, you haven't used them yet have 'ya, just takin' up space I say.

Have you loaded the bronco with all your gear and measure with you in it? My rake is also significant with a bumper and winch but rides level when ready for travel.

what I do lose is the ground clearance and want to get the heavy/heavy spring setup from EMU but they don’t have a sku for the 2 door and no eta.

I installed the Heavy springs and struts from old man emu with top spacer, brought sas back to ride height and no nose diving while braking.

So you put OME heavy on stock (SAS?) Struts without issue? And Why the need for the additional spacers?

 

[Berggie]

I used the OME struts and springs. I used the spacers because I am running 37's. So it ended up level with my 2 inch SAS lift.

 

[andersman02]

OME springs require different struts. If I went that route I'd probably do 6100's

I was a bit confused today. With 1/2 tank of gas I measured my rake for shits. It's at about 2.25" measured again on different flat ground- the same.

Before I do anything, I'll recheck the rake before filling up, and after, as well as with a couple hundred lbs in the back, to compare.

Right now I'm leaning towards ~1.5" front perch or 6100's. Eibach springs are out. Really don't want to loose the SaS suspension though, as I am an OEM guy at heart.

My measurements will be the deciding factor I think. Not sure I'm crazy or what, but I wouldnt have thought 1/2 a tank of gas could add .75" of rake
