4th Gen Suspension Options/FAQ

[PronouncedJIF]

Got the 5100 lift kit from bilsteinlifts.com with the 1.75" B12 rear coils but I think I'm going to try staying with stock front coils. Thinking about setting the front 5100s to 1.75" to keep the front close to level or small rake. Any thoughts on this?

any suggestions for a basic street suspension combo?

Should end up with slight rake once it settles

Postin this in a couple areas to get advice before I can make my own thread. Any advice appreciated!

Problem: Getting bad rubbing during turns on rear of front wheel well and on body mounts. Want to clear rubbing and make this thing at least somewhat capable on and offroad. Red area in pic.

Setup:
2006 4Runner V8 Limited 4WD
Coastal Steel front bumper (~120lbs I think)
Bilstein 5100's front (2.5" lift) and rear (unsure of lift setting)
Bilstein coils / springs in the back (B12 heavy springs)
OEM coils / springs up front
285/70/17 tires (32.8" diameter)
FJ 17" Wheels with 1.25" Spidertrax spacers
JBA High Caster Upper Control Arms

Questions: What can fix this?

Would OME 886 coils in front on 0" Bilsteins achieve more lift to help this? I went to alignment shop and asked for as close to 4° caster as they could give me but they basically lowered them both I'm at 3.3°L/2.77°R and getting pretty bad rubbing. Was hoping to make this thing at least somewhat capable offroad, and at least driveable on the road lol. What else can I do, or do I just need new / smaller tires?

Got the Bilstien 5100s with OME 855 2” Medium coils, if I set the shocks to the highest setting at 2.5” and still pair them with the coils will it mess up my suspension?

I doubt changing any coils will fix the rubbing and you already did the casters setting so I would say your best option is a BMC.

I ran 285's for years with no rubbing running with a 0 offset wheel but once I changed over to a -10 offset it rub at the same area at full turns so I had a SPC specialty alignment shop set my casters and it helped but stilled need s a BMC to be fully capable off road.

2003 Limited Suspension - What should I buy?

Hey, I have a 2003 v8 limited 4.7L with the xreas system. Because of the xreas, my normal mechanic is afraid to mess with the suspension even though I've suggested they could just remove it and replace the suspension like a normal truck. I've called around and another shop was spooked by the xreas too.

They seem to feel better about me buying the suspension parts and coming in just asking for them installed. I don't know what I'm doing, but I want to buy the right stuff. I do a fair amount of offroading, but I also do a lot of towing a 16 foot trailer so I don't want to lift the 4runner and affect towing. I'd like to do this as cheaply as possible, so I don't need the fanciest option.

I've heard Bilstein 5100s could be a good option, although I called Bilstein and told them I had the xreas and they said they don't recommend their products then!

Anyway, has anyone replaced the suspension recently who has or knows my setup? Could you post links to what I should buy? Everybody talks about FJ coils in the back, but would that raise it?

Sorry for asking a question that maybe has been asked too much, but I appreciate any help I can get!

Finally put my lift on my 2003 4Runner, used Bilstein 5100s on the front an rear, used 5th gen coils on the rear and stock 4th gen coils on the front with the bilsteins set to 2.5” I’ll reply to the post with an after picture.

I just installed 5100s and so far they’re a lot smoother, look up on YouTube how to do a xreas delete and install the 5100s at a do it yourself shop

2021 Tacoma Suspension swap?

Hey all, new to the forum and am looking at potentially upgrading the suspension on my 05 SR5 and I found a set of 2021 tacoma suspension parts, shocks, struts, UCA's for a pretty good deal. Does anyone know if these parts would be compatible with 4th gen 4runner?

the front shocks will fit but if you want to lift your vehicle get some actual shocks and you can use the 5th gen coils, the 5th gen shocks will fit the rear but you have to modify the frame. I used the stock 4th gen coils with bilstein 5100s on the front set to 2.5” and stock 5th gen coils on the rear with bilstien 5100s it pretty much leveled the vehicle out and gave it about 3” of lift and it’s a lot smoother. You get get a full set of 5100s for around $450 and it’s well worth it if you want more than 3” of lift you’ll have to get different UCAs (not stock)

I just installed 2020 Tacoma UCAs and front coilovers on my 2007 4R and they're plug-and-play on 4th Gens. You need to change the bushings in the rear shocks but that's easy to do. See the "X-REAS delete..." post linked in my thread for more.

These are the 2021 tacoma parts I was speaking of

Great and helpful info, thanks for sharing!

Interesting, okay. Thanks for the feedback — that's partly why I'm confused, I keep seeing posts on these forums of people that are running 285's with no rub and with less mods then I have! I believe those Trail Edition / FJ wheels I'm running have a +15mm (1.5") offset, but with the Spidertrax 1.25" spacers I believe that is reduced to about a +6mm offset (is that correct?) Wouldn't a -10 offset make for a pretty damn wide stance?

Looks like I may just need to do the BMC (though I worry this won't solve the tires rubbing on wheel well / quarter panel plastics) or just switch to some narrower pizza cutter tires for my next set of rubber. Was hoping a little extra lift in the front could help, but perhaps it won't. Wish I could find a good shop around STL!

Also, I did go to the shop to try to increase caster, and from what I understand the JBA high-caster UCA's should allow a good amount of play, but I still only got ~3° caster from the mechanics there (was hoping for 4° or more but they told me they wouldn't do it).

The rub actually got worse after installing the high-caster UCA's which was disappointing, but I was partly thinking the shop that did the alignment didn't really give a good attempt at increasing caster for me. Before the JBA UCA's caster was supposedly at 1°L and .7°R on OEM UCA's, and yet the rub was much less severe. After JBA install but before alignment caster was at 3.19°L and 3.98°R, which was updated to 3.3°L and 2.77°R after alignment, but either way it's now rubbing worse compared to OEM.

Body mount chop is probably your only option.

It's definitely an option on the table, but I see so many build threads like this where it seems running 285/70/17s simply isn't an issue in regards to rub / clearance. For example:

https://www.toyota-4runner.org/3351961-post36.html

He's running: same wheels, same tire size, same spidertrax spacers as me. No mention of rubbing / body mount chops, etc. From what I can tell he may be sitting a bit taller than me in the front (~1"), and about the same in the rear. Hmmmm...
