I was referring to this statement, "driving on the highway locks it in straight even if i let go of the wheel going 100k's an hour on 44's".

I just wanted to ensure no was afraid they would end up too stif to even try ram assist.

I see it is an old thread. I was just playing around in my truck and got a little overzealous to share again---Sorry!

 

if the steering was too loose it would be all over the place and would wonder.

 

Nice ram i have the same brand but swivel heim ends

Its actually not ideal though. When i do it again i will go with a psc 1.75x6 stroke with high steer.
You guys want some REALLY good advise on hydro assist...
Read this page of this thread I replied too it has all the pics https://www.ford-trucks.com/forums/1...teering-4.html

 

Now that you read that heres the deal with making the BEST hydro assist for on and offroad.
When we did my bros high steer setup hydro assist we found that with the tie rod located over the axle the ram only needed to trave a total of 6"s. Now my 1.5" bore ram gives good power and acts well on the street I could upgarde it to do better. The problem is the bigger ram you go with the slower reaction time the steering response is due to it taking more time to fill the extra fluid needed. First is to get a saginaw pump and drill out the back passages to allow more flow or buy a AGR "superpump" of some sort but my saginaw after testing with a professional tester puts out 1500 psi the same as they advertise with the "superpump". Anyways it will be scary on street if you were to go with say a 2" bore.
Now heres the thing:
with high steer beacause you only need a 6" stroke vs 8 I would use a 1.75 X 6.75 X .75 ram from PSC because now it only has to push 3"s in each direction vs 4 it should act the same speed as the smaller ram.
The larger bore gives more power but the smaller diameter rod actually creates more "pull" power on a ram. My ram is a 1.5x8x 1" rod . Problem is the 1" rod part. You need a smaller rod for that more "pull force but not too small where it is now weak.
A ram will always have more "push" power over pull back power..
Punch in some #'s on the ram size you want to use on this calculator and you'll see the pull never is equal to the push but gets closer the smaller diameter of rod.

Basically that PSC ram is the best of both worlds for power and street manners when done with high steer!!!
here are the results on my 1.5 ram
push 5301 lbs
pull 2945lbs

Psc ram
push 7216lbs
pull 5890lbs

for psi rating i put in 3000 psi on both

As you can see the psc rams lower pull is still higher than my "push" on my ram.
much better

 

I have a little air compressor that pushes the same PSI as my $800 compressor. That does not mean it can move any where near the CFM. How much volume does your pump push compared to the "Super Pump". I could run a 2.5 inch bore with a larger pump and have it be just as quick as my 1.5 inch ram. Actually, my 2.5 inch on my YJ with a large pump is faster than my Super Duty. But I would prefer to have a mechanical connection still for my daily driver. In this setup the larger ram and pump would be a waste of time and money.

 

"Basically that PSC ram is the best of both worlds for power and street manners when done with high steer!!!"

-It just depends on what Surplus Center is carying that day. I have seen some that appear identical to what the top hydro setups are running!

 

How much is that PSC going to cost? I You can build this whole setup for less than $200, about $150 if you get the right fittings the first time. I can turn my tires on pavement with one finger. I also have 12,000 miles on my setup, mostly with trailers.

By the way, those are swivel ends on my ram. I am not saying my setup is better than a PSC.... Well actually for me at this price point, it is better than a PSC setup.

 

The psc is about 200$ with the tabs and ends. If your after a "good" cheap setup the surplus ram is fine. If you want the best psc is the choice. I just had to find it out on my own like most of my junk and I'm more than willing to upgrade to get my truck to perform it's best.

 

$200 is a pretty good price. I believe Surplus center is building PSCs stuff. I would be happy to buy a PSC ram for the same price though, just to have the PSC sticker on it. And the lighter color would look a little better than the boring black ones at Surplus Center. I know it sounds gay...but It is nice to have something stand out a bit after you have put the time in to build it.

 

haha i do know what you mean but it all looks like crap in the end anyways when it gets used a abused. Look at my motor in my avatar pic. Do you think it looked like that for long with the header wrap bombing through mud holes? I make things nice too hell i used stainless washers with grade 8 bolts on my whole truck..Theres about 350$ in just hardware

i could probably just get by with a 6" ram but to not take any chances i would just get the 6.75" one like above

 

If you are anywhere near Fort Benning, I will come check out your junk!

 

[QUOTE=73 ford guy;8411698]I usd this diagram to find where to tap my 2wd box.


thanks for the info......

 

[QUOTE=highntight;13447415]Good stuff!
Hopefully it all worked out

 

[quote=73 ford guy;13447439]73 ford guy

ok need you knowledge sir....

just want to double check before i start drilling. this is a

Ford F100-350 truck 68-79 Power Steering Gear Box 2wd right?

Ford F100 350 Truck 68 79 Power Steering Gear Box | eBay

if i could get some detailed pictures of yours drilled and tapped ide surly appreciate it. thanks again....

 

That's the right box.





I like to drill, tap , install fitting, then run a small 3/32,7018 rod weld pass around base. Buy little caps to cap off if you ever wreck a line on trail and your back to regular power steering.

Welding with that rod is best over wire as it will burn out any oil or impurities causing it to weep or leak! I'm a certified welder
