Bilstein 6112/5160 + B12 Springs

[Guru6022]

I have done it and may be the first ever, maybe not, to have installed Bilstein 6112/5160 with their new Bilstein B12 springs.

47-259768 6112 front

25-227611 5160 Rear

53-291387 Front strut Spring. This is supposed to be 14" 650b spring for an additional 80-140 pounds of front weight. It only works with the 6112 strut. Some info states it lifts an additional 0.5" but when I called Bilstein they said it does not lift an additional 0.5". I was told to use the original clip settings so get the desired lift height with the additional front weight. I wanted 2" with additional weight so that's circlip #4 for my kdss vehicle per the instructions. I have stock 6112 coils which are 600lb and 14" i think that I try to sell off later.

36-281824 Rear springs. These are supposed to lift an additional 1.5" in the rear without additional weight. They have a 1" lift spring option but no one has it and its on back order until nov or something.

I just finished the lift and no weight on the front yet but the rear seems to have gained 2"+ eyeballing it. The front with out the winch and winch bumper is also super high about 3in. The winch and winch bumper should be about 130lb total. I haven't driven the vehicle as it still needs to be aligned but ill provide some feed back on ride quality. I have been told that the suspension needs to "settle" or "break in". Is this true? I did realize that I don't have pre-lift height measurements, I was too excited to get started I totally forgot. Ill get measurements post alignment and post winch/winch bumper plate install, then measurements again 500-1000 miles later to see the difference. I hope it does settle, it looks like I have 3" front and back now. Im keeping stock 265/70/17 tires, and stock UCA. Ill get some pics up.

How do you like ride quality? Did you go from stock to the 6112/5160 setup?

On Bilsteins website, I think the clip setting instructions are different with the different coils 600 vs 650. I am set at 6th clip setting with the 600lbs coil and netted 2.7” in line with the instructions.

Also, I do think it takes some time to settle right after install, especially with a 650lbs coil.

I swapped my 600lb springs for Bilsteins 650lb sometime in spring and I could find very little to no info. I did manage to find the clip setting info for the 650lb and I based my decision off of that. Initially I had it on the 7th clip for about ~3” lift (w/ KDSS) in the front but moved down to the 6th clip once I swapped to 650lb springs. I am currently at about 3” with lo-pro bumper, winch, group 27f battery and arb twin compressor with 1 gal tank. I was afraid of leaving it on the 7th setting and possibly over extending the KDSS system.

Help, so I was about to install my lift. I just saw this and it totally screws up my setup. So I was installing the rear Dobinsons springs which are supposed to be 1.5 but apparently their like 1.75.

The 6112 springs only have settings at 1, 1.4 and 1.7 and so on.

So with this theory, if I do a 1 inch lift, I will get 1.5 for the front and have a 1.75 increase in rake from the back. If I go with 1.4, I will end up at 2 in the front and 1.75 in the back almost eliminating rake.

I want to maintain my stock rake and had planed on 1.75 across the board. What should I do? So frustrating.

You are referring the KDSS clip settings with the 600lbs coil, correct?

I am at the 6th clip setting for 2.7” of lift with a 1” Eibach rear coil that is really 1.5” and I have slight rake.

I’m actually looking at the 650lb coils.

I will be installing my Slimline and Warn 10K.

Just found out that the 650lb Bilstein springs has a .5 lift.

I was trying to do 1.75 front and back, but the .5 extra changes that. Either I will be 1.5 in the front or 1.9 (ie 2) in the front. My rear coils will always be around 1.75.

I just don’t know which way to go!

Tough call - I keep going back on forth on that also. I would call bilstein and ask their opinion. I think they have pretty decent customer service.

I actually called them today as I am close to doing the install. I have winch, rear Dobinsons coils, JBA high caster uppers, 6112s, 5160s, and B12 specials all sitting in boxes, just still waiting on that slimline Front bumper 13 weeks later to get shipped.

I looked up Bilstein’s manual last night and sure as shit it says adds .5 lift. Today he said that’s without any weight on the spring. I said, but the spring description says for front ends with up to 130lbs. He says yes, it should be close to zero with that much weight.

I said then why would you say plus .5??? Anyways, it a a circular line of questioning that personally I think could be avoided. I just wanted to share in case someone else is looking.

I think it would be best to go with an equal lift in the front and back and have 1/4 inch less rake than go lower and have an increased rake.

I tow a small trailer and personally couldn’t imagine having a reverse rake by leveling it out.

I also have the brand new front 600 lb Bilstein coils that came with the front shocks if someone wants them discounted w/KDSS.

Good info! Sounds like a solid build. Do you know the coil pound rating for the dobinsons coils? Good luck with the install and post pictures after. The Pro folks can run the 600lbs coil on TRD bilsteins for some lift so I don’t think you will have problems selling that pair of coils.

The rear Dobinsons are 10% over stock. I will point out that apparently the 1.5 lift ends up at 1.75 and the 2 at 2.25.

All this gets super confusing when trying to coupe that with the front spring height.

Bilstein does make them at stock with a lift in case you wanted stock. I didn’t want to go too stiff myself...

Just got back from vacation, up loaded some pictures and the alignment specs. Caster is close enough to 4 degrees on stock uco and it handles better than pre aligment. Did have to replace the lca, had to be cut out due to frozen bolts, what a bich.

I took post lift height measurement and post 200 off road mile measurement but I can't find the paper I wrote them on!!!! The height did settle down after the 200 miles and it looks very nice now. I'm much happier than immediately after lifting with no miles. It handles better than before and it rides smoother than stock. On the washroom board I didn't even have to air down like before due to harshness. Tires are at 36-38 psi on the road on p rated dynapros. I was very surprised how much smoother the ride is offroad even at street pressures. Once I find my paper with the measurements, I'll post it.

It was my understanding that the rear dobinson coil is 1.5" lift on 4runner and 1.75" on fj cruiser when I spoke to them. I had planned to use dobinson but their front would not fit the 6112 struts. I wanted to keep both springs the same manufacturer

 

[Blue4Fun]

That’s what got me too. Nope. 1.75 on 5th Gen without third row. I had several back and forth discussions with Mike at Dobinsons.

I wanted to bump this thread to ask a question. I just bought the 6112/5160 setup. I’m going between the 1.2” and 1.6” setting for the front. If I do the 1.6” setting, will I need the B12 1” coil springs to keep the slight forward rake? I have a 2018 SR5 4wd non KDSS. If anyone has a done this setup or have another rear spring idea to get the 1.6” lift in the front do you mind sharing some pictures? Thanks in advance. I’m also planning on KO2 tires but torn between 265 vs 275.

Just had 6112/5160 installed yesterday! I stuck with Bilstein springs. Love the ride. Night and day over stock.

I did the 2" setting (6/4 for non-kdss), and used the Eibach 1" in the rear. Sits pretty level with 275 ko2.

That looks awesome. a couple questions for you:

1) what setting did you use for the front? 1.6" or 2"

2) which Bilstein springs did you use - 1" or 1.5"

3) are you running 265 size tires?

thanks for sharing.

your truck looks clean. i think 2" is too high for what i need. so if i did the 5/3 setting for non-kdss, then do you think ill get significant forward rake with the 1" rear springs?

Maybe a little bit of rake with that setup, if you can live with it I say go for it. You could instead do a 1/2" spacer in the rear

 

[safdSA]

All good questions!....but I don't know! I'll call the shop and ask. I told them I just wanted 2.5-ish of lift and they set it up.
Tires are 255/75, just to be different
