Currie F9

Just wrapping up my Long travel and SUA on the 19OR. In the final touches I'm realizing I want to swap the axle and go custom width to best match the front. Ideally what are the thoughts on doing this. I would like to get as matched to the front as possible (Camburg's LT kit). I measured the front WMS to WMS today and came up with 67.25" Not sure what I did wrong. Referencing this thread: https://www.tacomaworld.com/threads/installing-a-currie-ford-9-in-a-tacoma.545890/

On a +2 front kit, he went 68" rear to better match the front. Im not looking for a perfect match, but like to be close. like to hear some thoughts.

 

Well you probably wont see many responses because it doesn’t make much sense to swap to an F9.

It’s a lot of money to swap an axle purely to increase width when there are no clear advantages for doing so.

It would have been more reasonable to SAS the front.

Maybe look into wheel spacers?

 

Dont we all do this for aesthetics? Camburg's SUA kit requires the wheel to be spaced 1.5" minimum. Im at this point in the "kit" right now. With no spacers at all, the tire will rub on the shaft of the shock. Im not sold on spacers, which would instantly create a weak link in the rear. I know there are plenty of people running them, claiming no issues. How are they driving it, where, how fast? ...now for me, with any articulation the tire will rub on the shock. So, I actually require probably a minimum of 2" wheel spacers.... So just for aesthetics, no not for aesthetics. To clear 3.0 16" bypass shocks. It amazes me how often I see people dump money into something and then half ass the end.

Not sure if you have looked at Currie's website, but they make a F9 for the Tacoma. An issue with swapping axles in our Tacomas create a world of issue with the ABS and ESP sensors. Without these sensors you'll need to run a standalone and the truck still wont shift correctly. Currie has taken all that headache and made a pretty clear straight forward swap, of course in stock width, but one phone call away to whatever size you want.... 30 spline vs 35 spline, larger diameter tubes, ring gear has a third bearing on the pinon, which Toyota does not. Did I mention you can ditch the elocker, run ARB in any drive, not just 4LO? I'm not stating the 8" is weak, however, too narrow for my application. I guess I should of mentioned I'm not overlanding.

 

Don't know how well the Ford 9 will do in the taco works but in the Jeep world they are great.

I'm assuming it's a big bearing 9 in. I believe you can run 35 spline?!

What size tires are you planning to run? Usually if smaller than a 35 you are losing some ground clearance.... Unless you do a shave...

 

Interesting build to say the least..don’t take this the wrong way since everyone has their own vision for their trucks but it doesn’t sound very well thought out.

Without us knowing what your vision is, and how you intend to use your truck it’s difficult to understand all of the decisions involved.

3.0 shocks are a bit overkill for our trucks, 2.5” shocks on standard relocations require wheel spacers so a 3.0 would further complicate that. If you didn’t consider a different axle in the design then another option would have been inbording your shocks within the frame and bed.

The SUA is a neat, I looked into myself but for the money it would just be better to 4-link the rear and add a truss. SOA to SUA adds some benefits but it’s a bit of a band aid, but it’s easy to install and likely satisfies your needs.

Someone can correct me later but the new Toyota axle already has a bigger/stronger R&P with 32 spline 1.32 axles which are similar to a Dana 60 and 14 bolt, it’s pretty robust.

From a weak link perspective, you always want the weakest link to be a cheap and easy part to replace , if that’s a wheel spacers then so be it.

Just providing some constructive feedback, I know if I was going to spend $8K+ on the rearend it would be 4-linked and caged.

I would check out the long travel suspension threads and maybe post your question there. You may get better responses from people running a similar setup.
