X-REAS Delete + New Suspension Install
Update Jan 2023: Replaced the front Tacoma coilovers with Eibach. The Tacoma gear was still good but I decided to go with Eibach all around. First time I've ever had all new springs and shocks and the ride and handling are superb. Also installed LCAs and sway bar links from TRQ/1A Auto.
Update 21Aug22: Changed out my rear suspension over the weekend. Took off the FJ rear springs I've had for 3.5 years and ~82K miles in favor of some NIB Eibach E30-82-073-01-02 I picked up from forum member

. I've had Bilstein 4600s (p/n 24-186049) on the rear for a year-and-a-half and 32K miles. Swapped them out for Eibach's E60-82-008-02-01 (new from Jegs) since the 4600 is for stock height. Picked up an inch floor to fender well with the new setup, from 36" to 37". I find it tough to get a precise measurement from the center of the hub but it went from ~21.5" to 22.5" IIRC.
I got Eibach front springs in the deal as well and will do the front once I find a bargain on their front shocks.
I'm still a huge proponent of the Tacoma suspension swap, which is a great, cost-effective short- or long-term solution for 4th Gens. For me, the Tacoma swap was a terrific choice as an upgrade to my worn-out X-REAS and gave me the time to figure out the direction I want to go long-term, which is the Eibach setup.
Update 09Aug22: I found a great deal on some new-in-box Eibach springs and have also ordered Eibach rear shocks since the 4600s I'm running are designed for stock height. I plan to swap out the rear as soon as the parts arrive and do the front later as I'm still very happy with my 3rd Gen Tacoma setup. More to come after the install.
Update 18Jan21: I have reconfigured my suspension as follows:
Front: UCAs & coilovers/Bilstein shocks from a 2020 Tacoma TRD Offroad, taken off at 3700 miles.
Rear: 4Runner specific Bilstein 4600s (p/n 24-186049); kept the 2007 FJ springs previously installed.
Love it and highly recommend these components for a budget-friendly yet highly capable on- and off-road setup. More

Original Post----------------------------------
I finally got the X-REAS swapped out and the difference in ride quality is night and day. Much, much smoother now and it handles better too. Bonus: the new front springs added about 1.5" of height at the fenders and 2" at the front lower skid plate (right under the bumper) that leveled out the rake nicely even with the .25" the rear springs added.
Before going to the gear & install, my reasoning may be helpful to anyone considering this swap. Suspension choices are tough b/c this isn’t a shirt you can return if you don’t like the fit. Ride quality is so subjective and opinions so varied such that it's tough to know whether someone’s advice applies to you until you bolt the gear on and drive it.
If possible, regardless of what setup you’re looking at, see if anyone in a local 4x4 group has it and will let you ride shotgun. Even a trip around the block will leave you better informed to decide where you want to invest.
In my case, I'd rather risk $200 to see if I like this than spend hundreds more on a setup I may or may not like and will either be stuck with for a while or lose money reselling it.
Update: this setup is terrific on & off the pavement. See my linked YT channel for off-roading videos.
Here's the new setup:
Bilstein 4600 shocks and front springs from a '15 Tacoma TRD Offroad ($130 from local Craigslist)
2007 FJ rear springs ($70 shipped from a FJ Cruiser forum)
Energy Suspension rear shock bushings (Model 9.8108G [hourglass] or 9.8140G [straight - may work better])
Parts are plug and play except for the rear shock bushings. Here's a
thread about ways to change the bushings and
my post showing how I did it using the Pitman puller method. Be sure to get
this one (Autozone p/n 27022). It’s the smaller of the two that they loan. The “jaws” on the larger one are too wide.
Also needed a 22mm wrench to disconnect the X-REAS fittings at the appropriate place (not at the shock!) so that was $7 at Home Depot.
I bought new top mount nuts and lower bolts, washers, and nuts from Toyota for $42 including tax but returned it all as my original hardware all worked with the new gear.
Scrapped the old springs and shocks at a local yard and they gave me $4.20 for them. Woo!

Happy to answer any questions, and I also put together a set of PDFs from the Factory Service Manual that provide a lot of useful info including torque specs, directions for removal of the entire system or shocks only, and so on. As with anything, this is for reference only and it's your responsibility to use whatever is helpful to you in a safe manner. Here's what is included:

Disconnecting X-REAS
I couldn't get the 22mm wrench on the fitting and turn it without bending the wheel well wall in a bit. Just tighten down a crescent wrench all the way and gently bend it toward you, then slide the wrench down a bit and do the next little section until you have enough room. About a half-inch in was enough. When you're done, just gently bend it back. I had some black spray paint handy to cover any spots where the coating got scraped.
It's slow going to disconnect the fittings b/c you can only move the wrench a fraction of a turn each time. Here's one of the rear fittings with the wheel well bent out of the way and the fitting partially loosened. The pic is a bit deceiving as it looks like way more room than it is. Bracket at left is where the rear sway bar link attaches. It has to be removed to get to the fitting.
This one's off and I'm ready to remove the shock.
The bottom spring mount is designed such that you rotate the spring until the end runs up against a stop as shown. This is the old spring before removal.
After installing the new shock and wrangling the spring for a while, success!
The front X-REAS fitting is tougher to reach and is easier to confuse with the brake lines. Be sure to follow the tube from the shock to the fitting and be sure you have the right one.
The FSM disposal instructions say to remove the banjo bolt and drain the shocks. That was only possible for the rears b/c it took 5-6 extension/compression cycles to empty them and I couldn't budge the fronts with the old spring on them. The fluid was amber and remarkably clear. It's just a trickle in this pic since I didn't have enough hands to compress the shock and take the pic.
Old rear spring vs. new-to-me 2007 FJ spring. They're sitting upside down; when installed, the rounded end is on bottom and the flattened end is on top.
On to the next project!
