Called Eibach to get the compression ratings for their pro-lift kit -

Told me 375lb/in on the front, and the rear is progressive from 165-288/lbs inch for the rear.
Considering my Dobinson front is 610lb/in on the front - yeah, this should me a for...
yup, you feel my pain. Are you running the HOSS 2.0 billsteins? Someone else mentioned that the springs might "top out" the shocks and are literally preventing them from travelling much (if at all).
I just made an $1800 mistake with my springs and need to fix it.

Do you happen to have the compression ratings (lbs/inch) for the springs and coilovers?
That was my original plan - until this person mentioned, "Oh, but perch collars are 'double compressing' your springs with the extra weight - you don't want that. The right way to do it is to add a better spring...."
Ahh well - like I said, just posted this up here so others can learn from my...
Where did you find the spring rate on those? I can’t find them online anywhere.
Also, do you know exacly which part # springs you got? They offer 4 different versions, one that’s HD for 2D, one that’s HD for 4D...
Short term options (knowing that each of these carries $1200 in labor / alignment charges + parts).
a) put back in stock springs, add a perch collar to front to level it out?
b) go with eibach springs (anyone know what the compression rating is on those?) - which would give me *some* lift and...
Very effective!
Absolutely 100% my decision to spend the money and do this and should've asked more questions. I think I'm just so new that I wasn't sure what questions I *needed* to ask to get the right result.
I'm a little mixed on the point that the person making the initial...
LOL! Exactly.
After the fact, I learned that the heavy duty springs compression rating is something like 600lbs/inch - so I could add a chubby family of 3 up on the nose, no problem.
Well, here's where it gets interesting - the front springs were so overkill, that I was asking the shop where I was doing the work if we shouldn't just take them out and put in Eibachs for something softer - they steered me into ordering the NON-heavy duty dobinsons for the rear so things would...
**edit** - after being miserable for 3 months, I saved up and had them pulled out and replaced everything with the Eibach Pro Truck 2.0 coilvers and everything is WAAAAY better and smoother now. So $1800 to put them in + $2000 to replace them with Eibachs = expensive lesson learned.
*unless...
Perfect timing - Fraser from Mobridge actually responded back with exactly that.
Put the Morel Tempo Ultra Integra 402 MKII's in the front, and the 602s in the kickers.
Nice! That's in my future upgrade list after I financially recover from the front bumper and lights I just put on. I have HD Dobinsons going in the front....
I just put these on my front (after adding about 160lbs of steel bumper and winch)

I looked at the Eibachs - but noticed they didn't even have a...
