TRD Pro fronts need replacing. 6112's???

[TRDpro4R]

Hey all,

See the specs in sig for current setup. 57K miles later between the preloading and extra weight from the slimline bumper and roof rack, I am getting a pretty rough ride up front with an occasional clunk and some bottoming out. I am also getting a decent amount of sag on the front (about 1").

I was thinking a spring with a higher spring rate (thinking 600lb versus the 520lb stock) would help the sag. If I could find taller springs, then I could ditch the spacers (and preloading problem) and hopefully get a better ride. Unfortunately that spring (600lb and 2" of lift) for use on TRD pro shocks doesn't exist. Dobinsons is working on one but it is not currently available.

So I am thinking about just replacing the whole front setup with 6112's which happen to come with 600lb springs. My understanding is that these are identical to stock TRD pros but adjustable height. They would provide enough height adjustment to level out with the SAW coils in the back (I got 2" lift with them) and the spring rate increase is a similar percentage (15% increase on front, 12% increase with the SAW coils). My questions:

Is this dumb? Is there an easier fix that I am missing?

Will this work with the factory TRD pro rears and SAW coils how I mentioned?

I am not interested in ICONS, Fox, Kings, etc. Well, I am :hail: because they are cool but they would be overkill for me. Vast majority of my miles are on the highway with a handful of camping trips each year that get some off roading. No rock climbing either.

Thanks for the help. I have spent the last two days on this site reading through countless threads on suspensions . Head is spinning haha.

The spring you want does exist, I run eibach 14” 600lb springs with the spring perch on the lowest setting, if you want 2” of lift then install the spring perches on the upper setting or for less preload leave it low and get 15” 600lb springs, here is my pn used Eibach (1400.300.0600S) $100 each on amazon. Beer me up Scotty!

if you want to stay with nice red toyota trd springs you can try to score some trd fj pro springs, trd tacoma pro both 3x14 600#, or trd tacoma baja pro which is the 650# version.

Do you have a link for a 15" version? It was my understanding that pretty much every spring manufacturer uses even numbers which seems to be the case on Eibachs website as well.

Only other problem with this that I could see would be no one knowing if you can run a 15" spring on stock TRD pro 4R shocks. They do not have adjustable perches like the 6112's. Mike at Dobinsons is testing this to see if its possible but as of currently, I do not think anyone know for sure that is a safe setup to run. Again, talking about stock TRD pro shocks, not 6112s.

The 600lb 3x14 would be good for the added weight and should get me about a 1" lift on the front. I could leave the rear stock but was wanting a little more lift. More like a 3/2 lift overall. or 2.5/1.5

The trdp front shocks have two settings actually was as the 6112’s have 7 if I remember correctly. Ok yea after some more searching it seems most other manufacturers only go up in equal increments

i could be wrong here, but as the previous poster mentioned the 6112s come with 7 height settings and i'm fairly certain they also come with 3x14" 600lb springs as standard

They do. The advantage with the 6112's is the adjustable height. This allows me to pair with the 2" lift from the SAW coils on the rear. There is no spring available that will work the factory TRD pro shocks and provide a 2-3" lift that I am aware off.

I have 6112’s and 5160’s from Bilstein with Icon 2” springs in the rear.

I am using Falken Wildpeak AT3W’s in 285 70/17.
I have SCS RAY10’s
Size: 17 X 8.5
Bolt: 6 X 139.7
BS: 4.30"
Offset: -10mm

The front 6112’s are set to 2.5”:

The rear with 2” springs:

I maintain the factory rake with 2” springs but I am planning on a new rear bumper with swing away spare tire.

I thought the stock TRDP front set up was a TRD/Bilstein 5100 shock (46mm vs the 6112 at 60mm), and the rears were either a 5100 with external rez or a 5160 with rez. Not so?

This looks fantastic! Favorite wheels and the gray/bronze combo is perfect. Do you happen to know your ground to fender or hub to fender measurements? Specifically, how how is the front end with the 6112's set at 2.5". Did the Icon springs provide an actual 2" of lift or more?

I'll soon be having the same issue, looking at a full front bumper and winch - originally I never planned on rock crawling but I love it and the spacer lift doesn't cut it, i'm looking at the off the shelf 6112's until the 8112's are available for the 4R platform.

I'd like to know if anyone has used the 6112 (not pro 6112) with a full front bumper/winch without sag? setup?

The front spring rate on TRD pros is 518lbs. The 6112's come with a 600lb spring rate which should help compensate for some extra weight. Depending on how much weight you plan to add will determine whether it will sag or not. Check out this thread from Dobinsons:

You can get an idea of about what spring rate you need based on your estimated weight from that info. I know if you order your 6112's through Wheelers, you can order them with higher spring rates (650 or 700 listed on their site).

Decent, I didn't know that thanks!

No problem

Yes, starting at the rear ground to fender 40”

Center hub to fender is close to 25” it looks like 24 but I was holding measuring tape with one hand.

Front is about 38” ground to fender

Center hub to fender in front is about 23”

Top of front tire to fender is just under 7”

Top rear tire to fender is about 8”

I would say the springs provided 2.5 of lift in the rear. Hope that helps.

Thanks so much! That was exactly the info I was looking for
