Geiser vs Eibach vs Collar

[K223]

Thanks for relaying your experience. I was also disappointed to learn that there is no good way to run 37s without a huge level of effort.

You can but you really can’t go full blown Baja off-roading unless it’s done right. Stock offset BL wheels work better than most aftermarket offsets, and you still have to trim the truck up. More mild off roading or mall crawlers can get away with it. Most who want the power back will need to tune as well, as the tires are a bit heavier as mentioned.

Front fenders and trimming pinch welds is mandatory if you want 37s and use your truck for what it was designed for. It was completely worth it to me!!

I would caution anyone with a 2019 who wants to add Eibach springs to level truck. I was hoping to get 1.7 inch lift to level but instead I got 2.75 inch lift. Now my front is an inch high and drives like crap. I have an appointment with Ford to recalibrate the live valve ride height sensors but that’s not going to change the height. I can add Deavers +3 to get level but that idea is going in the wrong direction. I am now going to put the original springs back on along with 1.5” collar and forget about it. I sent pictures to Eibach and they said that 1.7 lift is only an estimate. So it’s my bad.

This, and my experience described above, are examples of why it’s worth paying for experience and quality reputation.

I do a lot of work myself. That’s easier on a simple, solid axel, Jeep than it is on a Raptor. The Raptor is the product of some really fantastic engineering and some much-better-than-average components. I should have known better than to trust a confident local shop without actually confirming they had been successful modifying raptors in this way. As it turns out, they hadn’t. They were relying on the vendor and manufacturer of the product — so we all learned an expensive lesson.

I plan to mount up the Eibachs and Deaver +3s, and then replace the hacked up front fender liners. I’m hoping the truck will be back to factory performance and steering with slightly greater clearance and firmer ride.

Most new springs require about 4 weeks to settle. This is common with all of them no matter the brand.

I'm not a fan of collars as the factory springs on the truck progressive rate springs. What that means is the more they are compressed the stiffer they get, so as you compress with a collar to get the additional height its changing the base spring rate and making more firm. Thats why some people say that collars = harsher ride, but it will depend on how much height you add.

The perfect solution would be for a vendor like SVC or Camburg or BajaKits to take a stock height linear rate spring and combine it with a collar similar to how KW Coilovers work on Porsches and BMWs, but that product doesn't exist for this truck even though I have suggested it to all 3.

It’s not worth their time. Geiser has a progressive spring and eibach has linear springs covered.

Both lack adjustability. Guys like Loctite above wouldn't have an issue with the combo. It also helps with corner adjustments as sometimes springs don't settle the same so you can be off .1" to .5" in height from passenger to drivers side.

Maybe truck guys don't give a shit, but as someone with a car background that shit is important to me.

EDIT: They could buy the linear springs from Eibach for the set up. I've talked to Eibach and they can make them but it's 100pcs min so it simple for a manufacture to make this set up. Literally 1 phone call to place and order for stock height springs and then they just add them to their existing collar set up.

I have been running Eibachs on the front. They gave me that 1.7” height increase and got me dead level. The springs never settled either. If they did, it was not measurable.

I have seen 2-3 guys including @Loctite with the dreading squatted truck after the Eibachs were installed. It doesn’t seem to be the norm and can’t imagine a particular truck to be that out of spec or were they not installed correctly or may the shocks be locked out some. Ride height reset is a must, many of us eventually found out on the 19s and 20’s.

I believe the rear ride height is the same as before the springs were added. Just got too much lift out of the springs. The truck has 8,000 miles. I don’t think the rear springs are already sagging. Anyways the truth is, I didn’t check around with guys that have experience with this set up before I jumped in and had it done. I made one phone call to an experienced off road shop and the tech told me to take them off and sell them. End of my story on this screwed up deal
