    I have been in the market to purchase a full hydraulic system for my new project for a while. After doing a ton of research, I was going to go with PSC out of Texas, however, during a club Show-n-Shine a couple weeks ago, I ran into David Hagan and his bad a$$ Jeep!
    [​IMG]

    David spent 16 months building this Jeep and you would not believe the amount of engineering that went into it. The best part, David owns a machine shop and he custom built most of the parts himself!

    Anyway, after spending some time talking to David at the show, I asked if he would build me a ram and his response was sure. Then I threw in, can I come and take pictures of the build, he said yep!

    His ram starts with a 1.75" Diameter shaft that weighs in at 21.5 lbs. It is made from Hydraulic Shafting 1045 steel. It is turned and ground then hard chromed. He machines the ends to accept 5/8" ball bore Heim joints and he recommends running the 3/4" shank version. He personally runs Nationals Black Max Heims on his rig.


    [​IMG]

    Next he builds the piston using a two piece ductile iron unit that is the standard in the hydraulic industry. To seal it, he uses a large o-ring between the piston and the shaft. This stops any leakage that would cause slop in the steering. He then uses a teflon ring to seal between the piston and the housing. Under this teflon ring is another o-ring for extra sealing and to help support the teflon ring. He also installs a composite wear ring on the pistion.

    [​IMG]

    He then installs the piston in place on the shaft using TWO snap rings on each side of the piston.

    [​IMG]

    Next comes the cylinder. He uses hardened hydraulic housing tube that is then machined and honed to precise tolerances. He then tigs in the bungs. The housing weighs in at 10.25 lbs!

    [​IMG]

    The ends he uses are a machined work of art! He uses buttress threads on the ends which, again is standard in the hyrdaulic industry. He uses Parker poly packs to seal the ends which includes two o-rings, an inner seal, and an outer dust seal.
    [​IMG]

    Next he made me a set of spacers that reduced the amount of travel to my requested 9.25". I measured this on my Rockwell axle and this is the maximum travel I wanted to run. He said he has built rams for up to 10" of travel that guys are using on the Rockwell...
    [​IMG]

    That's it for parts. He then lubes everything really well with hydraulic fluid and puts it together.
    [​IMG]

    [​IMG]

    Oh, he also included a set of these sick clamps to mount the ram into place.

    [​IMG]

    David is a super nice guy and has been into racing his entire life. He is very knowledgeable with hydraulics and I would highly recommend his ram over anything that is out there. His pricing is very competitive, and he will not lower his quality to produce a cheaper product to compete with some of the stuff that is out there. If anyone is interested, please send me a PM and I will get you his contact information.

    If you need a ram I would call David!

    Nice link to the software site. There are a bunch of companies making hydraulic assist kits. Some good, some not good. I run the WTO kit on my '90K5 and all is good when the ram is not leaking.


    btw, this is not a hydraulic assist ram. This is for full hydraulic steering.

    Also IMHO I'm not sure of the use of your rig but if its driven on the street I wouldn't want to run full hyd. steering system, too much at risk in the result of catastrophic failure ecspecially at high speeds :blush:

    Hey I am in the market for a double ended cylinder....got a couple of questions....

    Why did he use spacers on your cylinder if he custom machines these things? Why didn't he design it for the correct stroke if he builds them?

    Why did you use 2 different sizes of spacer? When using 2 different sizes your rod will not be centered when you are at the center of the stroke...


    This leads me to beleave that he gets the parts then assembles them or customizes them to work with your setup. If so who did he get them from? Prince ? Cross ? Someone like Tisco????

    Does he also give you all the seal #'s so you can put together an extra packing kit? It would suck to have a seal go out and have to figure out what this guy used in your cylinder to repair it.

    I can get a PSC 1.75" tube. 2.5" bore X 8" stroke, 1.5" rod, 3/4-16 female both ends, #6sae female ports From Blue Tourch Fabworks for 275$ online. Or the Surplus Center ram for 199$. I know I can get the packing kits for these cylinders if the seals go bad. Can he realy compete with these prices?

    You are ass-uming a lot. I don't plan to drive it on the street. Especially with the 46" Michelins. :D

    I guess I'm just used to reading the idiotic posts from some of the rednecks on pirate who would put a full hyd. system on a DD running 53"s :eek:

    Thats freakin sweet. I want to do mine exactly like that. How much do you think you have into your convert so far? Are you going with pinion mounted brakes?

    I am trying to stay on the cheap with this build... I probably have $2K in it so far. That inlcudes the '89K5, axles, 46" Michelins, springs, ect.

    That does not include the cost of the Atlas II, driveshafts, beadlocks, Detriots, or any other expense I need to button this thing up for the trail...


    Yep, I am running pinion brakes. Got the Screamin Seeman kits... The calipers came from a local salvage...

    [​IMG]

    However, I am seriously debating on dropping the leaf springs in lou of coils and a linked supsension... The leaves are real close to my ram and I have more lift in front than I want. If I pull a leaf out or replace a "lift" leaf with a stock leaf, the spring pack drops and gets even closer to the ram... : mad:
