OME 883 or Eibach

I have a 98 Tacoma ext cab 3.4l 4x4. I currently have the OME Nitro front shocks with 881 coils. I am wanting to add an ARB bumper with a warn m8000 winch in the near future. I was originally thinking of going with bilstein/Eibach combo. I like the height I am sitting at right now with the 881. Would it be better to just add 883 up front? What is the spring rate difference between the Eibachs and OME 883? I just dont want a lot of sagging with the added weight. Thanks

 

883s are ~590lbs, im not sure on the eibachs, the eibach coils that the second gen guys use with 5100s, the toytec ultimate lift kit, uses ~620 lbs spring. Im not sure if you can use the same coil for first gens

Edit. Looks like the eibachs are 620 And heres some good info

I would think you should be comparing 882's vs Eibach since 882's are taller springs vs 883's which is the same height just 881 500lbs vs 883 590lbs.

 

That's the thing, wouldn't I need stronger rate coils rather than just taller coils? I would rather have stronger rate coils (883) that hold their height over time than having some sag in no time (882). I am fine with the heighth I am at with my 881 right now, but I will go higher with the Eibachs if I need to if they would be the better option with an ARB bumper/winch.

 

Here is my dilemma, I have the OME shocks w/ 881 on my truck right now. Would I better off swapping to Bilstein/Eibach or just swapping from 881 to 883 for a bumper and winch? I want to know which combo will hold up my bumper and winch better over time. I am not concerned about the lift difference between the two, just their ability to hold up the extra weight. I would probably get a top plate spacer for an extra 1/2" or so with the 883 if I went that route.
