Steeroids disappointment
http://www.corvettesteering.com/55-57%20chevy.htm
I have installed one of these and was very satified.
norval, what's the big attraction to the Jeep box? I took a quick look and it appeared to me to be just another pitman arm control box similar to the original stock except smaller.

"Must be a "Jeep Thing" cause those Jeep guys are right.......I just don't understand.

As Norval said, the Jeep box has the PS control valve built into the input side of the box, eliminiating the dino-tech "catch-up" control valve on the steering linkage. That system doesn't provide power assist until you the pitman arm starts moving. The Jeep system kicks in as soon as you move the steering wheel.
The bracket flex you mention has to be an exaggeration. Turning the wheels with the car at a stand-still yields the highest loading the steering will ever see other than an impact. Movement of the rack at this point is a matter of the mounting bushings and the brackets. Keep in mind that performing the same test on the stock Corvette steering will result in the frame flexing because the loads are so high. This is a good time to mention to everyone that you should have any car rolling (even slightly) when turning the steering. This will significantly reduce the loads placed on the steering and frame.

I assume this kit bolts to the power steering pully and then to the manual steering linkage via the pitman arm??
Any fabrication/mods needed to fit this to my car that is currently manual steering?
My car has the early steering box, will a stock early rag joint bolt to the above power steering boxes?
Was just about to order the steeroids, now I am rethinking the situation.
Thanks guys.

Yes it's my alter ego ;-)
I've posted several times about the play in my steering wheel. I've probably got 5 degrees or so of play, and it drives me nuts. I watch the linkage while my wife moves the steering wheel back and forth, and I can see it moving around. It's just inherent movement that I can't get out.
I checked Speed Direct's website for answers, and I replaced the lower column bearing, but it didn't do much. The reason they push the bearing idea is because of the way the kit is engineered, it's loading the column laterally (which is not natural for the column). The u-joints operate near their maximum range at all times...not well engineered at all.
After all that ranting though, I will say that the car does steer better with the kit. I just wish they had a better solution for the u-joint design.
Hoses: The high pressure was fine but I needed to make my own low pressure (71/406 SB).
Brackets: Yes, the brackets allow some movement when turning the tires at rest, but so do many GM and Saab brackets. When the car is in motion it's not a problem.
Steering Play: You can minimize any U-Joint binding by spacing the Steering Column rearward.
Ground Clearence: Yes, it hangs low, but not lower than the pan. That said, I think this is it's greatest weakness. If you car is lowered then this is an issue that the Jeep Box doesn't have.
Feel: There's no way any Recirculating Ball Box can have the road feel of a Rack & Pinion, no way.
Install: Steeroids, bolts in with some minor Die Grinding of the Frame in my case. Took a couple of hours with a helper is all.
Install: Jeep, requires moving the front Brake Lines as I understand it, though I've never installed one. How easy is it?
Weight: Steeroids.
Price: Jeep.
I like my Steeroids, but I'm sure both do a good job when properly installed!

The jeep box is of the newest design. I don't believe it came out before 1999. It has a very responsive control valve right at the input of the box.
And like ratflinger said gone it the slave cylinder, all the complicated lines that have to flex and the control valve.
It certainly isn't like the old box with it's catch up system.
It is 1/2 the price of steroids and look at the steroids installations. You hang this rack under the car, under the pan cluttering up the undercarriage. It is a messy install. Also look at the linkage with it's double universals to connect the steering column to the rac.
It is a micky mouse system, again there can be problems with binding in the linkage and I understand one of the pressure hoses can be a problem hooking up.
While BOTH systems were available to me very cheaply after good advice I went the more modern Jeep route , both a homemade kit and the bought kit. Both turned out very satifactory.
All I have left is a simple drag link running below the ban. The lines are extremely neat, don't need to flex so they can be routed neatly and I have nothing against Jeeps

I vote for Norval to please install a rack in his car for a test drive/season, and report to us as to which setup has the superior road feel, and so forth.....he is the only one of us with the time and talent to do this without spending a fortune......
what say Norval???

Gene I looked at alot of pictures of steroid installs and really hated how low that thing hung under the car, how it interfered if I wanted to drop the pan quickly, the linkage setup etc etc.
I really feel at $1249 it was way overpriced but again that didn't affect me since I would make my own system so cost wasn't part of it but it is for most.
I honestly feel the Jeep box besides being 1/2 the price is a great fix for out steering problems.
That said I also found the REAR stabalizing bar has a big influence on steering precision and braking control.
As you know I had problem under high speed braking and turning at the same time and the rear sway bar besides tightening that problem up totally made the car stable under rough road conditions.
Absolutley no twichness?? under all driving conditions
At that point I started bracing the frame in that area , even went to solid mounts and gussets on the frame rail motor mounts and will do even more this winter with the motor out.
You can not go far enought to support the frame in this area.
I would love to see a video of your flex as well as a stock setup. It would be a real eye opener.
I understand that everything is cumulative. When I installed the kit (a very easy project, and well thought out) I discovered the slop in my column support bearings. Unfortunately, I was renting a lift bay, and was unable to get the parts in time while I had the bay. (I also did the upper and lower A-arm bushings while I was at it)
With the front end on stands, and the motor off, I can go from lock to lock with one finger on a spoke.
I talked to many people, and read a lot of posts on your product prior to taking the plunge. The positive remarks overwhelmingly outweigh the negative, so I'm sure I'm experiencing an anomaly, and I'm not trying to drag you through the mud with this.
