hey, I a little birdie told me that you can use marlines hysteer for minipickups on fj60s?
is that true?
is that true?

Knuckle bolt pattern is the same. Wheel base is different so ackerman steering no longer exists...
Yup. His arms work. The tie rod and drag link are longer but he sells those too. The taper in the 60 arm is too big but a mini arm reamed for an 80 tre will fit on the 60 gear box and then you're set.
really? I would have thought the Ackerman angle would just change...
how important is the Ackerman angle?
when you change the Ackerman what will it do to the scrub radius?
FJ60 wheelbase is is withen a few inchs of most mini trucks
I am using the whole set up. Be sure, double sure, you tell them it is for a FJ60. The tie rod and drag link are different lengths than a mini, everything else is identical. And, yes their kit uses beefy FJ80 rod ends...
Ackerman angle? Does a lifted, 6000lb. boat handle tight enough to take advantage of Ackerman angle geometry?
4x4labs seems to thinks ackerman angle matters - at least they engineered their arms to keep it right.
coool! that makes things cheaper/easier!
Not trying to knock Luke. He does some awesome stuff
So does a 84 FJ40 and a 84 FJ60 run the same arms? The wheel base is 17.5"s different.
Mace do you still have your arms off the 40?
Ok after some searching...
a FJ40 has a wheelbase of 90"
a FJ55 has a wheelbase of 106.3" FJ40 Specs
both the 40 and 55 share the same track width. and according to SOR the knuckle arms are the same Specter Off-Road-Land Cruiser Parts - Search On-094-23
So I guess Toyota failed us again...
thanks Mace
I am not sure if the mini stuff and the 40 stuff share the same angles on the steering. But I do know that stock mini arms are the same as stock 60 arms (minus the stock J arm). The width of the axle is different (same as a 40) but they are angled the same and use the same pitch TRE's.
Honestly, I would not be concerned about ackerman. It is a nice thing.. but by the time you lift your rig and put 35" tires on it, you will never know the difference.
Considering that the problem with the rim back spacing is pretty constant between LC's and mini's.. I have to think that the arms are designes with the same angle....

IIRC Toyota never made Mini/LC steering akerman in the first place. Mini/FJ60 wheel base is close, but not the same. If you call 4x4 labs, the mini/fj60 arms are slightly different.
Like Mace and others say though, akerman really doesn't matter much in a 6,000 pound rig, I was just pointing it out....

it was not that they did not have any ackerman, it looks like they took the approach of finding a good middle ground that will work with a multitude of trucks...
BTW, ackerman never actually goes away if it was there in the first place. It just varry's off from the ideal setup.
Also, there are variations of the term Scrub and how it is applied to a tire.. When dealing with ackerman angles scrub relates to the tire scuffing while at full lock making a turn. When talking about backspacing, wheel scrub relates to the arc that the tire travels around the kingpin centers.

Good Info, thanks Mace
I've never heard any feedback from anyone running the 4x4labs setup. I know it's more expensive than other options, but does it work noticeably better?
It would be sweet if I could get my 60 to turn as nice as the wife's 80. The 80 feels like it actually wants to make tight turns, where the 60 just wants to go keep going straight.
Luke makes awesome arms...
Depending on your steering setup, a bunch of things might be the issue..
Caster, toe-in, etc.. The rig may behave differently..
Large amounts of caster makes a rig want to go in a straight line. And it will return to center very well.
Ackerman is not always a felt thing, exact ackerman is easier on tires and also makes tight turns.
Backspacing and rim width make a huge difference as well tho..
A 10" wide rim with 33's and 3.5" BS will have a greater scrub radius than a 8" wide rim with the same 33's and 3.5" BS. It will also turn easier..
Hey, Is There Anybody Else Who Makes A High Steer Kit Besides 4x4labs?
and behind the axle is better cuz it keeps it away from getting hit more often right? but does it do anything else that is good??
