For those that used the FJ springs. I had a DIY moment today and decided to do the FJ coils with 5100 on the rear. The coils did not seem to me to sit as nice/flush as the stock ones. I can get photo if need be. Any pics of how somebody's FJ coils are seated would be great and much much appreciated. I'm not sure how safe this thing will be with the ones i have now if they are not the right ones. The is my first attempt at suspension work.
Thanks guys....

My front has the Rancho quick lift strut.

Yea, wouldn't hurt to include year model, I know the 2010's require modification to fit. Thanks! Once we get a large list together in this post, I'll move it all to a spreadsheet, calculate some formulas, and post that back.

Thanks bro, for writing back. I have a 2007 XSP (SR5) 2 Wheel drive. I'm trying to get some pictures loaded of the spring seated as well as my truck. What got me is the fact they are supposed to fit 2007 to 2010.

Finally got the pics uploaded. I did not realize the minimum pixel size my phone took. I've enclosed a pic of the way the FJ rear springs are setting for me.

The rear moog FJ springs aren't going to fully sit down into the lower seat.
Some people leave them half seated and some return them and choose another option.

the moog fronts i used had the same issue. the coil is wound flat(ish) but isn't ground perfectly flat like the oem spring. it was close enough for my fronts, the rubber in the upper mount took up the slack. been running them for a couple months and they're fine.

Need to grind off

something like a 1/2 inch of the spring to get them to set correctly

Thanks guys. I was worried about they way they were seated. You guys eased my mind a lot. Thanks for the option about the grinding. I dont have the tools or time for that though. So I guess now I will let it ride until I find actual set of 07 FJ springs used. It seems to ride well. Thanks a lot guys. By the way if anybody is thinking about the Rancho quick-struts I have them up front. They are pretty nice. I used the same setup on my Tacoma.

Question for you all, sorry if its been asked before but I searched.

On rock auto they have two sets of front and back FJ springs listed with different moog part numbers

One is: Front=81092
rear=81083

the other is: Front=81108
rear=81081

When I searched the 81081 I saw post about unseated spring issues and the other set I found nothing on. The first set says RWD, does that make a difference and do FJ's even come just RWD?

So the question is are one of these sets right or wrong? Thanks in advance!

Search was using a 2008 FJ. A guess is maybe one set is for the 2010+ and maybe that why they aren't seating? So which set is for the 07-09? The first set? Both sets come up in a search for a 2010 as well.

One is for 2wd the other is for 4wd. You want the 4wd. I was able to get the driver's side rear to seat with a pry bar, but I had to cut about 3/4" off the other side with an angle grinder. It then went on super easy, and the passenger side still measures about 1/2" more lift.

Thanks for the quick answer, was the lift different per side with cutting one side?

Looking at your sig, I think you have what im going for. 5100s with fjs in the front for 3" and 5100s with fjs in the rear for .5"(I have a v6 4x4)

 

[nhaniger]

Awesome, I just picked up some 2014 FJ springs and shocks, I'll let you know what happens!

Hey guys, thread revival here.

I found a complete set of 2014 FJ Bilsteins and springs to replace my Xreas.

I've surfed through this and a few other FJ suspension swap threads. Can someone confirm the modding needed to fit 2011+ FJ Bilsteins on a 4th gen? I've read a few folks said straight bolt in, while OP's help link mentions there's some grinding and drilling needed to get them to fit.

Thanks!

From what I have read, the fronts should not be an issue. The rears are the ones that will require some modding, the lower bolt hole on the shock doesnt fit.... (spring should be ok)

I did the install after some more digging around a few weekends ago. Sometimes there's too much info around in the forum diluting the sources.

Fronts: Lower strut eyelet needs to be ground down.
Rears: Upper chassis mount needs to be widened.

Yes, that's true... I would say the best way to have a solid answer is to dig through the stickies and read almost every post lol, somewhere in there someone will have the same set up as you and already tried it.

Good information

Oh look another FJ Spring Swap...

Just installed my setup this past weekend.

2006 V6 Sport 4X4
Bilstein 5100 Front and Rear, set at 1.75"
2009 FJ Springs w/ around 20k on them
Airlift 1000
Stock Wheels with 265/70R17

Original measurements with stock springs and FJ black shocks.
Pre Lift
Front Driver: 33 3/8"
Front Passenger: 33 5/8"
Rear Driver: 35 1/8"
Rear Passenger: 35 1/2"


Post Lift
Front Driver: 36"
Front Passenger: 36"
Rear Driver, airlift at 5psi: 36"
Rear Passenger, airlift at 5psi: 36"
Rear Driver, airlift at 35psi: 37"
Rear Passenger, airlift at 35psi: 37"

Net front is spot on at 2.75" (1.75" from Bilsteins, 1" from FJ spings)
Net rear is 1/2" without airlift, 1.5" with full airlift.

I'll probably add a Daystar 1.5" to the rear to make it look better - I love how it looks when the airlift is at 35psi, but don't want to run that constantly.

 

[damthemainstream]

OK, I'm looking for some advice on where to set my spring perch on the 5100's. I have an '05 V8 4x4. I will be using Icon 2" lift springs in the rear, so I'd like to lift 2.5" to 3" in the front. I don't mind a little rake though, it doesn't have to be perfectly level. With the FJ front coils, should I opt for the 1.75" setting, or go all the way to 2.5"? I'd read some mixed reports saying that 2.5" may actually net well over 3", but I'm not sure if that's with the V8 and 4x4.

Assuming its like fitting 5th gen rear shocks, where people have to widen the upper chassis hole, I opted to mod the bushings instead so I didnt do anything permanent to the chassis. Been great for 10k miles.
