GEN 2 ***SOLVED***Please Help - My 19'' Rides like crap after Eibachs

***SOLVED***

2019 SuprCrew

I installed Eibachs a few weeks back. I wanted to give it a little time before making a judgement, but my Raptor is not the same truck as it was stock. In my research, most if not all are saying the ride was a little firmer, but overall an improvement over stock. This is not the case for me, as i now feel ever single bump in the road, im getting bump steer pretty badly, and the expansion joints in the highway are unbearable. My 2017 F250 i just sold rode better non the highway with 70# of pressure in the tires. As for my wheel/tire set up, I have 17 inch Venomrex 602s with 35x12.5 Nitto Ridge Grapplers filled to 37 PSI. One thing i did notice was I now have some negative camber. I dont have the print out of the alignment, so i cant check to see if i'm within spec or not. Would negative camber play into the ride quality? The offroad show where i got my springs installed also did an alignment and are a reputable shop in the area. They did the level on my F250 and it was perfect.

Has anyone else experienced similar results with their Eibach install. Any suggestions on things i could do to fix my ride? I want that buttery soft Raptor ride back!


I took this pic to show the negative camber. Its kinds hard to tell in the photo, but its there:

Here is a pic of the truck before the springs are installed (just because this thread needs pics)

maybe you got the old inventory Eibach springs with the higher spring rate everyone was complaining about?

 

[Simplejack]

other threads on here people were saying the live valve shocks have stiffened up since they expanded due to higher springs. might look into that??

I’m pretty sure I’ve solved the issue. I just ran the shock valve relearn process in the below thread and it made a huge difference. It still doesn’t feel like it did when stock, but i can attribute that to the slightly stiffer shock and 10 ply tires. I’m very happy with the results.

Yep, that was it! I just ran the live shock valve relearn process posted in other threads.

I thought the same thing for a moment. Turns out I needed to run the shock valve relearn process.

Just got my spring in the mail. Anyone know if I can check if they are an old inventory Eibach springs with the higher spring rate everyone was complaining about?

Mine felt even better after a couple weeks of break in. You’ll love em after.

I'm curious why you would change the springs? The stock Raptor rides amazing. Suspension is very well tuned.

People run to Deaver and Eibach without considering the impact to the overall result. There is a time and place for spring replacement but it really does depend on what you're trying to achieve. The stock Raptor is amazing and springs only improve things depending on what you are trying to do. Usually there is a trade off when modifying suspension. I'm gald in the end you achieved a result that satisfies you.
