full hydro on the street?

[br0nc0xrapt0r]

does anyone run this I need to know the basics how it works and what stuff to get.

I was looking at this kit.

You can't run that on the street. It's not DOT. legal and its not safe for highway driving.

looks like a trailer for me.

I had buggy with full hydro about 6 years ago. It was a HOWE double ended ram with 2 turns lock to lock. It was fine up to about 30 m.p.h. then got really scary really fast! Very touchy. The 3.5 turns shouldn't be as bad but I have heard stories about them. As far as legality goes I did a bunch of research on the matter before using it on my buggy and at the time there was only one confirmed report of any kind of citation for full hydro. That was in MOAB. That was 6 years ago so I don't know how much has changed but I assume most people including cops wouldn't even think to look for it. Looks like a nice kit!

well this is the way I was looking at it. I need new tie rods and a drag link soon, so spend 300 plus on new hiem joint setup that still needs a ram assist. also I plan on going full width dana 60's when I get back to the main land. so it seems to be the smarter route.

Also my driving consists of not really faster than 60 and only long distance is to a trail.

I also hear that full hydro is very touchy on the street. I think they tend to have issues when turning one way then trying to quickly turn the other way. Seems there can be lag time which could be a bad thing. but I do believe there are people that run them on the street. Although If you have to get any inspections done it may not pass.
You'll have to decide after its installed and see how it drives.

My hydro-assist is touchy enough, I wouldn't want to go full hydro on the street. Safety is a HUGE issue to consider. If power steering fails, you still have manual steering. If full hydro steering fails, you have a steering wheel that serves nothing more than something to hold onto when you crash...

I just bought 2 of these kits. 1 is for a trail only rig and the other is for a trail/road truck. I talked to different inspection mechanics in Pa. and they all told me that they did not know why it would be illegal to run on the street. In my searching prior to buying the set up It seemed the people who have the double ended ram said they really liked it and it did well going down the street. I am putting the first one on the trial rig now. I would prob think that some time in October I should be putting the other one on the street/trail and I can let you know how it does.

I've got the same kit and I've had my bronco comfortably over 75mph on the street. The PSC kit is great for the street, it actually drives better then the stock touchy power steering I took off the truck. Off road the kit shines as well - take a look through my build and you will see a few stages of my install. My initial setup killed my pump, the second setup didn't really work off angles and my final setup is flawless - if you don't have a problem cutting a hole in your hood to clear the reservoir.

Save yourself some time and money and DO NOT buy a cooler from PSC at the time of your order... I wasted around $100 doing so - purchase this cooler from Summit and it will keep your system the perfect temperature. I am going to buy another one for the transmission as these work so well.

As for people saying they are dangerous - they have not installed and run one of these kits before. You can turn the truck if the motor dies - just like any manual steering. As for it being touchy - that is because the pump output does not match the flow of the orbital or the size of the ram. The hoses that are used are a steel core wrapped in rubber and wrapped in flame retardant material that is rated to 3000 PSI. I have not found anything tougher and more durable then the hoses found in the PSC kit. The hoses (should) be routed from the orbital (somewhat where the old steering box was located) down the track bar and to the cylinder. If routed in that orientation there is very minimal chance a line would be damaged - or somehow torn free.

As for PSC as a company I cannot say enough - they have been very knowledgeable and are great at shipping things fast, even overnight.

Yeah kyle your build was what got me thinking about it about 800 bucks seems to be a waist when I could get that kit from psc.

Yeah - the kit's quality blew me away; the fittings and hoses are top quality. Money well spent - even with the caster I'm running to get a perfect drive shaft angle the truck steers great on the road.

How well does it turn those 37's?

I've worked on many many impements with full hydro steering, and there's no way in hell I'd use one on the street. at 20mph they're real twitchy. 75+? Fn forget it

I am running a complete matched PSC single ended ram system on a ranger truggy deal. I have put several miles on it with 42" TSLs on the road including one road trip while at Moab that was nearly 35miles(after running Kane Creek canyon). Comparing the way the ranger drives to my eb with ram assist on 40" MTR radials: The full hydro Ranger drives better. In the eb's defense it has 2002 tech on it but it is more twitchy, slower turning etc..... If you are not worried about getting "inspected" at a DL/seat belt check then I say go for it!!!! We don't have many safety checks at DL stops here in NC. I have gone through several over the years in the eb with beadlocks etc.....
HTH

You can't run that on the street. It's not DOT. legal and its not safe for highway driving.

Wrong and wrong. It's completely legal and completely safe.

I will be installing the linked kit on mine. I've driven a rig with that kit, and it's really no different on the street than any other type of steering. And yes, if the engine quits running, you still have steering.

Don't believe rumors, hype or false information.

Ok, I can't say it won't turn since I haven't tried to turn one with full hydro, my bad so let me ask this - how hard is it to turn withouth the pump working?

Ever tried to turn a power steering setup without the engine running? It's about like that. Hard but very doable and you still have steering without the engine running or if the belt comes off or if the pump fails...

In my experience many people who have problems with full hydro on the street can attribute the problems to other things, like having caster way off or some other problem. As others have said, and as long as your caster and alignment is good, a quality double-ended full hydro steering setup is as good or better than a good power steering setup at high speeds.

The system linked here also has an orbital valve that provides return-to-center steering like a steering box.

I don't work for PSC and have no stake in them, I just hate seeing misinformation spread around.

 

[KyleQ]

It is just like running equipment, it does not go back to center after a turn, and it is very interesting st high speeds.

No it is not - as the PSC kits are load reactive and will return to center when driving. There are two type is orbitals - non load reactive and load reactive. Please don't misinform people of what is out there...

How well does it turn those 37's?

Great - I need a shorter belt as it squeals when I put an extreme load on it but if I am 3 feet in mud or flat ground it feels the same.

This is a load reactive orbital with the correct pump output and cylinder size drives like a dream. Ever heard of the king of hammers? If not I suggest taking a look because quite a few 500 HP rock racers have no issues doing 70MPH + across desert whoops and in the same race crawl extreme rocks and hit the dunes again. Once again, mis-information

Exactly - this isn't a tractor or some janky assist setup. This is the result of true research and design, a top dollar kit -

Take a look at my pinion angle - I had complete disregard for the caster when I set this up as I don't plan on driving this thing to work and back. From full left to full right there is over a 3" difference in height of the steering arm - but on the street with 37" boggers, cut in the back with 15 PSI it drives like my F150, although it is smoother.

Well I stand corrected. I still find it hard to believe thats it's legal. I'll go with the "safe" as far as losing a belt or losing power. So I will watch the rest of this thread and see what others will say.

I still find it hard to believe thats it's legal.

Why? ?:?
