which ram for hydro-assist?

alright u have sold me away from the 2" ram.

so a 1.5" is gonna be strong enough, and isnt gonna be "just getting by"? just want to make sure, hopefully ill have a ram by the end of the month, just before i get the new tires :D
 
When you turn with a hydro setup that isnt fast enough it almost makes a grinding feeling.

With that said if I try and turn really fast with my 1.5" ram it just wont do it. I can only imagine how bad a 2" is. The 1.5" is almost to much.

A 1.5" is PLENTY of power to turn big meats. like I said I can turn my 42's with my pinky sitting on the asphault.
 
My hydro setup doesn't make a grinding feeling, it's just that you can only turn the wheel over so fast and if you try to go faster you've either got to pop it in neutral to rev it up (and speed up the pump) or attempt to muscle it which flat out doesn't work.

I'd recommend a 1.5" ram for a DD. I'm sure it has plenty of power. With my 2" ram I can stand outside the truck and turn the 40's when it's sitting on dry pavement. When I was in Hudson two weekends ago I was in a real nasty spot against a tree and up a creek really with one of my front tires up in the air. I actually lifted the truck at a 45 degree angle with the steering to help get me out of a hole, no effort involved, just let the fluids do the work.

Go with a 1.5" bore ram, it'll have more than enough power and if you do the pump mods it'll undoubtedly be quick enough for your DD.
 
Yeah, I know what you're saying. It's not easy to explain I just never interpreted it as a grinding feeling.

85, does rocklogic make any double ended rams?

I dont think so but I may be wrong.

I do know that there hoses suck though.

Not if the ram refuses to turn. Have you driven a rig with a hydro setup? (not trying to be a dick, honestly asking)

If you try and turn the wheel faster than the pump can deliver fluid to the ram, you're not turning anywhere. You've just gotta wait for the ram to catch up, it's just not possible to turn faster than the hydraulics are allowing you to.

thats true i totally forgot about that. ive never driven a truck with any hydro ram setup at all. i was thinking about how much quicker my friends turns over mine cuz the of the steering wheel. i have a ton more leverage though with my stock one.
 
Not to hyhack the thread, but has anybody every thought about using one of the old-style steering rams (before power steering boxes) as a hyrdo assist? I've seen them on old (60's ) chevys, C3 Corvettes, and 70's Fords (IIRC). I would think between the box and the ram it would be plenty of force for a DD plus the mounting ends might be more adaptable. Yes, no? :thinking:
 
Those of you saying that a 2" ram is too slow and the pump can't deliver fast enough....

I was just curious, are you talking about experiences you had with a stock pump? Has anyone used a 2" ram with the pump mods that allow for more flow? How slow is it like that? I've already got a 2" tractor style ram that I haven't installed yet, cause I couldn't find a 1.5" one that was cheap. Now I'm wondering if I should get the 1.5" before I put forth the effort to install the 2".
 
We are now distributors for Rocklogic hydro-assist rams and kits.

These rams are custom made for wheeling, double heim ends, 1.5x8", comes with pressure hoses, fittings and mounting tabs. These rams are have the right bore to keep your rig streetable.

Pictures do no justice, these are quality craftmanship.

If you are looking for a heavier duty cylinder we are putting together kits for 2x8" agriculture cylinders, these will be for offroad only applications, and much less expensive.

You provided the ported steering box and your set.

I was wondering the same thing. But here is my experience. I installed the WTO 1.5 ram on my DD and the stock pump was weak and I had slow steering performance. I replaced the pump and the problem went away. So if you bought a performance pump I can see why it wouldn't work well with a 2" ram. I bought a truck that has full hydro on it with the correct pump and a 2" ram and I can whip the steering from side to side with out drag. So if you want to run 2" ram on the street I would spend the money and get a really good pump not a stock style replacement.
 
I have not touched my pump as of yet, but it is in very good shape. I would know, I had to replace it shortly after I bought the truck. :crazy:

You could definitely make it more livable by adding the mods or going to a pump that's actually designed to move that much fluid, but if you have the choice between 1.5 and 2, just use the 1.5. 2" bores on assist systems are honestly unneccessary IMO.

Full hydro, yes, 2" is a good bore. If you were driving a dedicated full hydro system there was probably an HO pump somewhere in there to deliver WAY more fluid than our factory pumps were ever designed to. That's undoubtedly why there was no lag.

Try the pump upgrade here, I just did it. Super easy.

Those are the pump mods I was talking about. I was just curious if those alone would make the 2" somewhat streetable. I wasn't really talking about aftermarket HO performance pumps. If it's really gonna be that bad, I guess I can get the 1.5" and try to sell my 2".

Are those rams available alone/separately? Or sold with the kit only?
 
at this years OFFROAD EXPO the company HOWE PERFORMANCE power steering had a booth, they do trophy trucks, compitition rock crawlers, you name it. the owner was who i talked to. they have a hydro-assist kit for Chevy trucks. they are very pricy but i think their kit is a great setup. i asked him alot of q's about hydro setups, he said, as some of you have said that yes it is the pump that causes slow turning, they dont recomend the stock pump at all, a modified pump that will push the volume is what they recomend. that is why they sell a brand new NOT rebuilt hi po pump with there kit, and they have upgrades to what the trophy trucks run if you wanted. the kit comes with a 2.0 ram, a huge remote resevore with a screwon type filter like on an engine, ALL the parts in there kits are new, even the steering boxes that comes with the kit.

one thing i found most interesting is that he said a power steering unit is basically like a hydro tube bender, it will keep stroking until it reaches its stroke limit. he said the reason why chevy trucks are notorious for ripping the box from the frame is because the internal stroke of the box is more then what the steering componants will stroke, so when they reach there limit the box wants to keep going and the week point is the frame. he sets the internal limit in his new boxes alot less then the factory does so it stops at the proper limit. he said if a box is correct you dont even need a frame brace like everyone uses. he said some boxes might be only 1/4 in from there stroke limit but if all else has reached their limit the force on the frame is alot, for street driving with stock tires it probably in most cases on most trucks wont ever be an issue, but when you throw huge tires on and start rock crawling or mudding where you crank on the steering at the end of the stroke things are gonna break. there hydro kit is my next big purchase.
