HOSS 3.0 Perch Collars vs Eibach Springs vs Eibach Coilivers

[derichio02]

Hey all,

I have a 24’ Wildtrak with Foutz 2/1.5 collars (2” collar only gave me about 1.5” up front). I want a bit more lift for my 37’s and wanted a few opinions on ride quality. I’m mostly on fire roads and some moderate obstacles to get to my fishing hole.

Option 1: I could simply order a foutz 2.5” and move the 2” to the rear as it’s the most cost effective and simple and I wanted to keep a bit of rake.

Option 2: I could get Eibach 3.0 springs. This will give me more lift up front but I may be level and I heard it’s stiffer. Is this true?

Option 3: Least cost effective, Eibach Coilovers. This I could dial in the lift but is this a downgrade compared to the Hoss 3.0 Foxes?

Thanks for any feedback. I’m not yet at the point where I want to spend the $$ for ADS or upgraded Fox coilovers. I did search but didn’t find what I was after.

Options #1 and #2 would certainly be the most economical to purchase however it will require removal/disassembly of the coil overs. I love my Eibach 2.0 coil overs but I'm guessing the HOSS 3.0 most likely have a better on rode ride.

I had the same but SVC collars, I hated the ride but loved the look. Just recently changed over to eibach springs and kicking myself for not going this route from the beginning. FYI going the eibach route your rig will sit lower than perch collars. I run 35's so I have no issues with clearance. Pretty sure I will switch over to ADS coil overs sooner or later.

Not sure if it would be a better ride, but the HOSS 3.0 should be less suseptible to shock fade due to the larger 2.5" tube and remote reservoir... Ride could be substantially better with either shock until it hits the outer limits of it capabilities. When you consider that the alleged goal of the WildTrak was high speed off-road, it makes sense to use a larger diameter shock to reduce the possibility of shock fade.

I have the Eibach 3.0 Pro Lift coil springs on my 2023 Wildtrak 3.0 HOSS Fox set up. I wanted more clearance up front for the Method MR315 wheels. I went with a 0" Offset wheel and Falken Wilpeak ATW4 315/70/17 tires which are a little bit bigger than stock and had a little rubbing on my mud flaps at full lock when backing up. Eibach advertises +1.9" Front +1.3" Rear increase with the 3.0 Fox setup. I got almost exactly that amount of lift. Between 1.75 and 1.875 on the front and about 1.5" rear. I still have a little rake front to back of about 3/4" higher in the rear but I'm good with that small amount of rake. So far liking the street ride. I personally think the Eibachs are a little softer and smooth out the hard bumps like pot holes. If it were me going with 37s I would go with the Eibach springs, JKS clearance kit and UCA and you should be fine.

Nice looking rig. On a previous Bronco I had RPG 3/2.25 and had zero rubbing with my BFG 37’s. With true 37 I would be up shit creek. I don’t hate the ride I have now just weighing out my options.

What’s your measurements ground to fender if you have them handy? Would be good to compare and see where I sit now. I have 35” Recon Grapplers currently.

On Falken Wildpeaks ATW4 (35") 315/70/17 tires which are just a little bigger than the stock Good Years and Method Racing 315 wheels with 0 offset. I got FRONT DF 40-1/8, PF 40-1/4 REAR DR 40-7/8, PR 41.0

Thanks! I’m running 35x12.5x17, Nitto Recon Grapplers, and Method 315, with Foutz 2/1.5 collars and honestly I’m a littler underwhelmed by the amount of lift I got. I may move the 2” collar to the rear and get a 2.5 for up front.

I also added about 80lbs of gear in the cargo area after the lift, my wheel/tire setup is only 7lbs heavier than stock. Also running 32psi

DF: 39.375
PF: 39.5
DR: 39.75

I've added a 1.5" collar to my '23 Wildtrak and a mount spacer to gain 1" of ride height up front to level out the rake about 10 months ago. While I think the perceived increase in spring rate has more to do with this shock's construction than pre-load, it highlights the fact that the shock valving needs to match the spring rate. Since the Hoss 3.0 shocks are height specific, adding a perch collar moves the shock piston out of the sweet spot for the internal bypass mechanism. The further you get away from stock ride height, the more you negate any benefit from these shocks. Not to mention you limit you bias your shock travel. I have to wonder how close a 3" perch adjuster can get to coil bind on the front strut too if the shock were to bottom out. 2" of spacer in the stock shock body has to just about eliminate any down travel. That's not really the concept of a suspension when it can only provide compression with some articulation. It might be acceptable if the truck never goes off road.

Earlier this week I drove a '25 Braptor and realized it makes the Hoss 3.0 seem like weak sauce. I want that level of ride comfort and control. Having added a bunch of power to my truck also pushes the Hoss 3.0 to the point that it feels a bit on the sketchy side when driving aggressively. The stock springs rate, while they provide a very soft ride, is a little too softly sprung for me. If the Eibach springs are lighter than stock, I'm glad I didn't try that avenue. I think jacking up the springs on stock type struts and shocks to gain ride height is not taking advantage of a longer shock body and increased suspension travel. I just ordered a set of Accutune modified Fox dampers as my solution.

As to whether to go Eibach or a better strut/shock package, that's going to be more of a personal budget issue. I think a spacer type lift that fits from at the strut mount would be a better alternative to big spring spacer perches or longer springs that are provided lift at the shock with these specific OEM Fox shocks. Zone has a lift solution for the Hoss 3.0 that's pretty cost effective and will keep your stock shocks in their intended cycling ranges.

Thanks for you input. I’ve been around for a while and have had 6 Broncos (2 Raptors, 3 Wildtraks, and 1 Badlands. I very much understand their geometry, pros, and cons. I have had 35-39s, collars and spacers, but have never had a spring or complete coil over change. I was honestly just asking to see who has had both to help provide a ride quality comparison.

I have the 3/2.25 RPG collars on my 23 WT. I am looking to get a little more height ...maybe 1.5 inches or so.

Couple questions (still learning the broncos)

1. Since collars don't change the length of the strut, does the preload gained not allowing as much compression cause increased CV angles?

2. Would adding the eibach 3.0 lift springs to the collars allow any more height or would I essentially just be squeezing them down to fit the top hat back on again negating the effort?

3. Would a 1.5" spacer work if the above doesn't or would I be way too extreme on the CV angles?

Thanks!

1. Since collars don't change the length of the strut, does the preload gained not allowing as much compression cause increased CV angles?

Regardless of lift method, the total amount of lift with the axle at full extension is where extreme CV angles come into play. You can measure the angles to see if there is too much droop, but the higher the ride height, the more your CVs will stay at a more aggressive angle in all driving situations.

2. Would adding the eibach 3.0 lift springs to the collars allow any more height or would I essentially just be squeezing them down to fit the top hat back on again negating the effort?

You should be able to jack up your front end and see how much extension is left at the shock from your current ride height. Whatever that might be is the maximum lift that you could obtain adding the Pro Lift springs with perch collars. But the combination of components is likely to render both front and rear shocks at full extension even under the weight of the vehicle, so you have no down travel of the axle because it's at it's limit. You want to have somewhat equal amounts of uptravel and downtravel, so you have a suspension that can not properly articulate over bumps. With that much pre-load using collars and longer springs, it may also result in a high spring rate that rides extremely harsh.

3. Would a 1.5" spacer work if the above doesn't or would I be way too extreme on the CV angles?

Not really. It's the same scenario, although perhaps slightly less extreme. Only if you were adding more weight to the vehicle, like a winch, it could have some merit. Either the springs of the collars will take the position sensitive section of the piston out the sweet spot it's designed around. I think the heavier feel from either of these have more to do with that than pre-load and/or increased spring rate.

For best performance with the Fox shocks on the Hoss 3.0, you want them as close to the same shock length as they are at stock ride height because of the position sensitive nature of the shocks. Zone makes a kit engineered to do that, but the front limit is 2.25", and does not alter the spring in any manner except for a minor perch adjustment. Lift is achieved by a spacer between the strut mount and the frame. The perch collar may be responsible for roughly .5" of lift and roughly 2/3 of that at the spring.

If you want or need more lift than that, you may want to buy a suspension lift that's properly engineered to give you that amount of lift and not cobble bits and pieces of kits to achieve a stance that may ride and handle like a buckboard. I would think such a kit will come with longer shocks that do not employ position sensitive technology. It would also make sense for 3" of lift or more that it also provide a means to lower the front differential to not overextend the CV joints as well. I have seen separate versions of these if not supplied in the lift kit. I've not looked into higher lifts, so I don't know what is available. You could sell your Hoss 3.0 shocks to offset the increased cost.

Thank you for such a detailed response. I assumed this would be the case.
Looks like I'll be leaving it alone!
