Alot of guys do the Hyraulic assist but is anyone working on some sort of rigid mount hydraulic system aka rack and pinion style...LakeRat??? Seems to me that alot of people go the other way and monster trucks use dual cylinders which is an option but am thinking that it might be possible?????

I don't know the specifics, but a guy around here that I kind of know does this on his mud-drag trucks. Not very complex I guess. He just mounts it up, runs the lines, and goes.

I've seen several setups like your talking abvout. I've seen them done 2 different ways. On one they mount the rack to a crossmember and then ahve the short links that go down to the knuckle. This works good for street or even in the mud, but will bind the short tie rods when even moderate flex is happening. On the other, it was mounted to the axle itself which let it flex with the axle. But then the steering shaft was always binding up because it had to have so much travel in the steering shaft to match the up and down movement of the axle.

Hummmmmm????? <IMG SRC="smilies/idea.gif" border="0"> Sounds like the perfect excuss for a High Angle Driveline CV steering shaft. What do ya think Jess, ever thought about getting into the steering shaft business?

LakeRat...the set-up I saw was just like one that you would find in a small to mid size car but beefy, 1.25" rods out either side and was rigidly mounted to the axle. The steering shaft was funny and wasn't anything I've seen before and had tons of flex(literally) I wish I had my camera to snap a few pics...it was well thought out but had to be super assisted since the steering shaft(sector) was almost like carbon fiber with only two u-joints....it didn't look safe but the guy insisted that it never broke....it reminded me of catching a 5 lb catfish on my tweety bird pole....

uuhhh!!! I'm not sure if you are just kidding or not??

All you need is a double sided ram (much like a rack&pinion)and an orbatal valve.

mount the ram to the axle and the orbital to your steer wheel, run the lines ang go.

WARNING: this is harder than you think, but still pretty easy to do.

P.S. that thing with the steering coulumn was realy funny (if it was a joke)

Nope, it wasn't a joke. But then again I guess it was if you had seen it TRY to work.
I've seen and done the double ended ram thing and yes, it does work well but that would be a full hydro setup, not rack and pinion.

Here is what we use, its a "Balanced" Ram, its double ended so when mounted it acts like a rack and pinion with two little tie rods but its actually full hydraulic so there is no dealing with the steering column.

Cool set-up Ant...got any more details on where to buy and such?

Like LakeRat mentioned is was a Rack and Pinion with a steering shaft....but this shaft was flexible with 2 universals to handle complex angles...will try to snap a few pic's this weekend...but I like Ant's better...

The ram has to be custom made, any hydraulic shop can make you one, everything else is off the shelf stuff.
