is hydro and ram assist steering the same thing or different....please explain

bleakhorizon · « **Reply #1 on:** Oct 28, 2010, 01:16:12 AM »

hydro assist and ram assist are the same thing, you use a hydraulic ram.... (uses a cylinder plumed from the steering box -> cylinder) still has mechanical linkage steering wheel to steering box to wheels

now full hydro steering is not...(uses a hydro pump -> steering valve -> hydraulic cylinder) has no mechanical linkage from the steering wheel to the wheels

thats wat i needed to kno but wat is beter...will the ram assist do the job cuz its a whole lot cheaper...

Depends on your setup. Full hydro steer is a little crazy so most will run hydro assist. The assist should be all you will need. Plus, if the hydro assist craps out on you, you still have a mechanical link so you don't completely loose all steering

what tire size? do you plan on EVER having on the road? i'de say for anything over a 39, full hydro would be nice. but if its ever going to see the road, forget about full hydro, its too dangerous. if your motor dies for whatever reason, or you lose a belt, there goes you steering with it.

yea i never even thought bout the engine driven pump on full hydro lol.... talk bout Armstrong steering.... that would suck...

for a yota axle the 8" stroke is more than enough... and most would run something like this https://www.surpluscenter.com/item.asp?item=9-4410-08&catname=hydraulic

but if you would need more power you could up the piston/rod size... but when you go bigger you need a better pump also...

I dont know where people get that you loose all steering if the motor is off or the belt breaks!!! All steering valves that you buy for a offroad vehicle or any vehicle will still operate. The only difference is that you become the pump yes very hard to steer but have you ever driven a 4x4 with a locker in the front without power steering same thing! The only time you loose steering is if you loose fluid, if one of the steering hoses break it wont turn that way but it will still turn the other direction... Hydro assist is perfectly fine as long as you dont have a long travel suspension.

Long travel as in Super long travel

If your leaf sprung, you will be okay.

Not entirely true... with most valves you will still have steering in those cases

Im sorry how does how much suspension travel you have deal with if you can run hydro assist or not ?

i have hydro assist on that.. 40" boggers 3 link etc and that is not full travel.. so i dont really follow

Only on an IFS truck it will matter.

er... what? how?

potter85 · « **Reply #13 on:** Oct 30, 2010, 02:58:12 PM »

long travel.... haha uhh there is no problem with that. unless you worried about the lines. but you can get any length line you want

True, I still turn with motor off, no worse than without assist.

@ Ironclad What I was saying is if you have long travel suspension (3link or 4link anything more than a leaf spring) it is better to run full hydrolic since when you have long travel suspension when the tire opposite the steering gear box is at full droop or at full stuff it limits how much your tires actually turn!!! If you havent noticed that when your passenger tire is at full droop it wont turn right as much and when its at full stuff it wont turn as far left

If you have FULL Hydrolic the steering is attached to the axle and always turns an equal amount!!!

Sounds like someone didnt build their suspension correctly.
im 3 link + panhard and have 0 steering limitations other than when i get into my bumper hard. full stop to stop on the knuckles.. still dont see how you figure that

hahahahah thats hilarous i raced a nova in hs that was a circle track car and it only turned left as well

potter85 · « **Reply #18 on:** Nov 13, 2010, 09:02:17 AM »

if you run full hydro on the road you cannot "feel" the road so around 50 plus you constantly start overcorrecting and will just lose control.
the hydro assist does exactly what the title says. it assists tho load in turning the wheels but being that you still have a positive mechanical connection you can in a sense still "feel" the road

k-nutty · « **Reply #19 on:** Feb 07, 2011, 02:18:40 AM »

how much does a basic hydro setup run ya?

Sparkplug · « **Reply #20 on:** Feb 07, 2011, 09:12:58 AM »

I did mine for 140 bucks, including tap what not. Hydro assist takes away a bunch of feeling on the road also. It lags a tad, and can get sketchy at times. But, like most things we do to our trucks, theres a tradeoff for off road performance vs on road performance. I will never again run a rig on 35 or bigger tires without hydro assist, Ive been ruined.

k-nutty · « **Reply #21 on:** Feb 07, 2011, 11:27:59 AM »

oh thats not to bad at all. and from what it sounds like the tradeoff is well worth it. do you recommend any certain brand ram or any other parts.

my buddy has a bronco with full hydro steering and its so easy to turn the wheel im in love ...just wish i could afford it for my toy $I\'m Down$

yeah i bet. haha

Rockin4Runner · « **Reply #26 on:** Apr 11, 2011, 04:22:36 PM »

I'm just curious, how do hydro assist. rams hold up to going somewhat fast across the desert (40mph). I'm not saying to drive the rig like a trophy truck threw 3' deep whoops at a 130MPH but you now, sliding at ass end around well going around turns and going across bumps that are roughly 8-10" tall at 40MPH

. Will it bend the shaft or blow the seals out on the ram?

Thanks

X2 and my truck is a dd. I did add a after market ps pump to my setup, it's so nice to turn 37x14.5x15 with finger tips.
