Do OME springs sag?

So I’m in the final stretch of my research. One of the options I am looking at is OME 885 springs on 90021 shocks. But out of curiosity, I looked into spring sag. I’ve seen reports of up to 1” on some 2nd gens. Is this normal? Did ARB change the metal in the springs? Or is it just another “Internet is full of unhappy buyers” case?

 

It depends. Weight, usage, and individuals expectation vs reality.

 

Springs do not lose spring rate or length over time; assuming they haven’t lost a significant amount of steel due to corrosion.

I take all reports of spring “sag” with a huge grain of salt. Ask those people how such sag was measured. My guess is that in most cases it was with their eyes and not a tape measure.

 

Okay. Well, my “pavement trail-rider” limousine will be used mostly for hauling stuff. My EL111r leafs have been good for 6 months, so reasonably, I can expect the same. My research lead me to “the sky is falling” reports then?

 

All springs and leaf packs will settle, OME though are known for it.

 

That is urban legend unless actual scientific evidence is produced.

 

The newer coils are indeed different than the earlier ones. Multiple people running the newer “x” versions with zero sag.

 

Steel has been approximately the same for centuries.

 

I agree. I havent seen an updated chart with the "x" coils. Meaning im pretty sure they have the same weight. I just installed a set on a 4runner and they had the x on the tag. So im waiting to see if the settle at all on a stock front end.

But if there is some info out there on the X's? Then that would be nice to know.

If OME i would just consider the 886 bc they have a 660 weight which matches better with the 3rd gen stock coil weight of 717.

Thanks guys. I am rocking a 2nd gen, old school ‘06, looking for about 2” of lift to match the back. I thought 885s were that to the 2nd gen? Move to the 886s?

 

if you are second gen then the sag conversation shouldn’t be of concern. The weight of the 3rd gen is is what most attribute the sag to, if indeed it even is legit.

 

886 is also a 14” coil. Which is a bit long. A lot of people prefer the 887 with a 3/8 or 1/2 inch spacer in addition to the OME trim packer. 888 is also an option that can remain above 2”

 

@908tacoma Thank you for that. So I should be looking more at the 887 or 888? Aren’t those 2.5” or 3”? ARBs site said the 885 with the 90021 shock was good for 2”? Or should I go with the 887 expecting some settling to around 2”?

 

you have to consider spring rate as well. I think the 888 are a bit harsh unless you add some weight up front. 885 is common but are you going to be upset if they settle below 2 inches ? Is the harsher ride with the 888 worth the guaranteed 2+ inch lift?

Also, it seems what you read a lot online about sagging is rarely when these coils are paired with the nitrochargers. It’s often the 5100 that people seem to mention they are running and experiencing sagging.

 

Here is a comparison that may help..not a 2nd gen like yours but

 

@908tacoma Thanks for the info. Pictures are great! My wife explains a lot to me with red crayon. 885s might be my answer, although 887s might be my answer. Much appreciated.

 

I used to have 885s and 886s and both sagged. Swapped over to dobinsons mrrs and there coils no sag.

 

People swear Eibach and Dobinsons do not sag, and I think their is some truth to that.

 

Thanks all.

Based on my research, where there seems an overwhelming number of “sag” reports, especially on 3rd gens, I went with my other option, where sag reports are few and far between.

 

There are over 25 different grades of spring steel listed on this web page alone, 8 of which are specifically carbon spring steel:

Do all of these have the same performance & longevity characteristics?
