No new pics, been buying hardware, mostly from Steinjager since I'm a dealer for them now.
Ok throwing this idea out there, any one ever done hydro assist with IFS?
Basic CAD layout, nothing in stone but something to have laid out to tweak on.

Design looks great, nice and stout!
Will the arms be CNC cut metal that's been boxed and ribbed for structure?
If so, I think that'd be one of the brawniest IFS setups I've ever seen.

Better to have a vertical upper pivot, horizontal lower. The UCA is a shorter lever, thus greater change of angle. Currently the design sacrifices steering angle and travel.

I did it with the orientation that way because I don't like the load of the lower ball socket from the spring force against the race sideways, it seems a better design to have it load with the ball mounted vertical. I have seen them built both ways.
I think I can still get the pivot angle.
Travel only needs to be 10-12", not building a pre-runner 4x4 setup(yet). I've got 8" travel Fox Air's for the front.

SCToy

Would be better to run dual verticals then to maximize travel to arm length since running a single vertical already limits steering angle.
You can always pull the axles to fool around prerunner style

Dang, had all the parts for the first time tonight, and as you so correctly stated not enough rotation is available for steering more than 15deg each direction. Good thing its a solid model and not a fabbed part.

SCToy

It's possible to get away with verticals if you aren't driving in cities much, but it is kind of a pain.

Good point, didn't I mention it's a trailer queen? It is and will always be except for the 20mi drive to the mnts on back roads.

SCToy

right, so generally you don't need a ton of steering off road because it usually just breaks things anyways. As long as you have enough.
The car I was working on had dual verticals and it really was only a problem on short course when you were drifting around a corner and you couldn't counter steer enough and it would want to spin around on you.

What kinda racing u doing with that? Looks bout like the figure 8 cars around here. They outlawed mud tires a few years back tho.

Any idea what the max steering angle from straight of a stock IFS Toyota is just for some reference? I'm going to measure my solid axle but I seem to remember hearing that IFS turns sharper?

SCToy

No idea, I don't have an ifs truck.
Also with ackerman, it's even less. Because the inside wheel maxes out the uniball first. Unless you kick them at a compound angle, splitting the difference of the ackerman so they max out at the same time.

SCToy

That truck fit in the trophy truck class in the VORRA series here, but they also do some short course. It's got skins that fit it. I don't know what it's doing currently. Not associated with the team anymore. I didn't design it, but I did most of the welding on it.

IFS sure does turn alot more than a SA

Yeah, definitely need to rotate the bottom ball to the flat position. I'm only hoping for about 12" front travel any more that works out is a bonus.

SCToy

Right, so in that case, I believe it would be better to put the snap ring down.

If the joint is going in the arm

Yes, don't want the spring compression load against the snap ring.
