Eibach rear coils

[Jamrock09]

I’m having trouble locating a set. I was told there Won’t be any in production until June 2019...

Any help is greatly Appreciated

Get the Icons 1.5" coils, you'll get anwyhere between 1-1.5" depending if you carry a full spare or not, quad cab vs crew cab etc, and if if you're doing offroad you can run 2" longer shocks with those, plus they'll also help carry more weight than the stockers.

I’m shying away from the icons I heard they are pretty noisy. But what the heck I might go for it.

Well, what is your goal for height, usage etc. Ram1500rsm, Bruiserram and revitmoto are running the icons, use them hard and don't really seem to comment much on the noise except for here and there. I have the bilstein rear coils and love them aside from being a bit soft and linear rate.

Depending on your end goal you have a few options, I gave up on eibach stuff in November when it initially went out of stock, and tho it's gotten good reviews, I'm happy it didn't work out.

Pretty noisy? Lol
There is “some” noise when you hit a speed bump, pretty much the dead coils hitting each other “once”. If it bothers you you can install spring isolators (I don’t have a part number but perhaps Bisltein or eibach rear will fit, I made my own for $4, they’re not pretty but do the job).
Bilstein 1” springs have isolators already but I think you only get 1/2” in the back after they settle although I guess the same conditions apply quad cab vs crew cab, full spare in the back etc.
You can also run any of the tuff truck ones but they are shorter than stock,again it depends of what you need springs for, I tend to forget not everybody around here is off-roading their trucks so some put heavy loads for work and spring performance is not as important, for some like me performance beats the crap out of a shorter spring because longer performance shocks are a necessity first then weight. Icons can do both well.

I need to measure mine again, I think I got about .75-1" lift now that I took my tool box out. That ******* weighed a good 250lbs, plus a spare, which would explain why I only got .5" lift, no matter as I'll forget to measure again, but my rake is visually more for sure

Those rear coils are still back ordered and I am not sure I would believe any ETA from them at this point. We have plenty of the ICON rear coils in stock. The ICON coils can be a little noisy but I honestly dont think its to the point of being annoying. I also wonder if customers are hearing the coils AND the bypass valves (2.5 shocks) combo of that makes it sound worse. The bypass valves will make a click noise as well. The owners with the 2.5 shocks seem to be the only ones I have seen say they heard the coils

You have to do a test like Bruiser did and throw 1000lbs back there so we can have a comprenhensive rear coil spring test

This is what Icons can give you on a quad cab from Bruiser's post
"SQUAT:

@ 200#: - 3/8
@ 400#: - 3/4
@ 600#: - 1 1/8
@ 800#: - 1 1/2
@ 1000#: - 1 3/4

Every 200# added was about 3/8" of squat, up to 800# Then 1/4" from 800 - 1000#"

We could infer that the Icons will compress 1" with 266lbs/inch on each individual coil on their first rate and it takes 533lbs of weight in the bed to push them down 1".
2nd rate starts at 800lbs, where it'll take 800lbs to compress the spring another 1" if it was linear, but because this things are progressive, the spring probably increases its rate pass 1000lbs, Icon old claim was 25% softer than stock in 1st rate, and 75% stiffer on the 2nd rate. We know given Bruiser measurements that the Icons seem to have a a linear rate up to 800lbs as the difference in height remains the same up 800lbs or 1.5" compressed, so you have that much room to play with weight before you're back to factory height.

Yea, I need to because that was an awesome nearly scientific test, but my weights are in my basement and that's alot of extra working out! That 3/8 with 200lbs is just about right tho, figure my box is about 250 and I'm sitting about that much lower than advertised height. Roughly.

I would like to match my front 6112. The most I will tow is my boat. And I do a lot trails from where I live 100km of unpaved washed roads to my house.

I’m looking for comfort and performance

I have a full thread on my setup. I'm running 6112s front with 5100s and the bilstein coils out back.

A great companion for those 6112's to match their performance will be the Icon 2.0 shocks with Icon 1.5" springs, they're diggresive like the 6112's, and you can get them with or without reservoir. The reservoir will give you extra longevity, both can be rebuilt and revalved.

You guys are awesome

Alright thanks to nick for hooking up a Canuck. I’m going with the icons.

Will be running a 3” body lift also. Nick do you sell those too. Maybe the PA system thank you

 

[Jamrock09]

Thank you everyone and nick for the coils.

I haven’t seen my truck in person yet, these were sent to me. I cannot wait to drive her.

 

[Jamrock09]

Wow major eff up on the dealer when I picked up the truck today. I went to wash and clean my wheels I noticed the tires on the rear are off size. Like big time

I live 100km away and they are closed until Monday morning. Should I be safe for now on my diffs?

 

[ram1500rsm]

Lol, ready for track duties with big meats in the back and skinnies in the front

Lmao it’s on the back I have one 295 and a 275

 

[hodge-xj]

So you have 3 295s and 1 275?

Do you have the anti spin rear dif
