I'm planning some upgrades for my crew cab this spring, I've ordered a aluminium radiator, led headlights and am going to install a Hydroboost braking system and new steering box.

On the redhead you can add as a option two threaded ports for hydraulic assist steering. Would this work for hydroboost or is it easier to do another way? (Cheaper too)

Also I have a Hydroboost unit available off a 1995 dodge 1500 2wd, 2003 Avalanche and 2006 F350 diesel truck. If any of those would work

I'd like to see where the ports are....could get pretty crowded under there with two extra lines coming and going.

This is the only picture they have on the website

Yeah I saw that one....those are just your regular ports.

mknittle

No because the extra ports on the redhead are for a ram that would go on the front axle(assist). so one is pressure and the other is return when turning one way and when turning the other they reverse.

The hydroboost is plumed so the pressure from the pump goes to the booster first then from the booster to the redhead.So you just want a regular gear with no assist.
Hope this is clearer than mud

gyman98

Yes it does, thanks!

Glad if I helped. Sometimes I have difficulty explaining what I am thinking It's a hangover form the cancer

gyman98

Well just a hangover is better then the alternative!

Do you, Brian or any one else have any feedback on the hydroboost units I have available?

jimbo486

This. Exactly. Hydraulic assist utilizes a hydraulic steering ram (usually mounted to the front axle or frame and connected to the steering knuckles) which gets its power from the steering gear box. A hydroboost system utilizes pressure directly from the power steering pump itself as described above.

Yeah, Brian has worked on the Dodge Units. IRRC Brian has had both Dodge and Gm units apart. I have only resealed the GM.

i used a GM unit from a G2500 van. bolts direct to the firewall and has been working well for about a year now. i'd bet its similar to the avalanche one you have. they came in 90s-early 2000s 3/4 and 1 ton vans/trucks. the astro van booster looks very similar as well but i didnt like the small MC reservoirs. here is the G2500 one(to compare to your avalanche unit)

gyman98

The Avalanche unit seems like a vacuum boosted model? The 95 dodge was too




The Ford unit

mknittle

ford is a hydroboost with a huge master cylinder. I don't know what the ford uses for lines or what the sensor/switch on the bottom is.


I got mine from a pre 95 Chevy astro van and bought a new master cylinder for a 94 Chevy k3500. the mount is a direct bolt on. I did change the pushrod to adjust the pedal to my liking.

mknittle

A couple pictures Ignore the pushrod in the first picture. I bought a thread stainless one and made a bushed end. last picture.

Hey Ashley....seems like the Ford is the only Hydroboost set-up. You could run it as you have it, or do some research and see if another MC would work...not sure if that tall unit would clear the underside of the hood....

Here's the thread I wrote up on my HB trials and tribulations....
