Has anyone installed one of these systems? How do you like it. Thanks

 

I did mine back stock, but if I had it to do again I would definately go that way over Steeroids. I have driven a "Jeep" box in a '71 and was quite impressed.

 

Just go to search and punch in grand cherokee steering . I've swapped one onto mine, but I can't comment on the performance yet.
Good Luck!

You mean Grand Cheerokee what year model? generally when you talk about a jeep box to fix into a C3, of what year model you talk about? thanks...

99-03, I think.

 

Had the Jeep box put in 2 years ago. No welding or cutting involved. It is a bit sensitive , but, I like it.

Tom is a pleasure to deal with.

 

When you say it is a bit sensitive, could you elaborate a little bit? Is this at highway speeds making the car feel darty, or lower speeds and the car turns very quickly with little steering input?

 

Darty at highway speeds . OK at lower speeds.

 

Is this with power or non power steering? I have non power and wondering if it's worth the swap.

I guess the engineers at GM got it all wrong upgrading the C4 thru C6 Corvettes to a rack & pinion steering. They should have stuck with the old worm gear box.
I'm very happy with Steeroids.

 

I have the jeep box too.
Its great. Feels just like my new 07 chevy trailblazer. Very minimal effort to turn the wheel and its 12:1 ratio is great. Alittle sensitive at highway speeds though. If you go with an aftermarket power steering pump like KRC you can adjust your output flow with a different size fitting which could help with the sensitivity at high speeds.
I have hooker headers and I had to really beat a dent in the side of two tubes to fit with the jeep box. I still think its too close that it is boiling the RedLine performance power steering fluid b/c I keep having to fill the power steering system with fluid. No leaks.

I read too many times about the crapy brackets of the steeroids kit and even got to twist a display model at Carsile two years ago. The darn brackets flexed right in my hands.

After my 5-6 speed trans upgrade in the next two years I am thinking about going with a rack and pinion setup if I can't solve the heat issue with the jeep box...but I want a R&P that is built well. Waiting for feedback with the new VBP R&P that just came out.

 

are the steeroid kits so weak that they are not worth getting and reinforcing? I don't know if I like the idea of twitchy at highway speedes. Does Unisteer make something for the C3?

 

That would help if the Jeep rack gets too much pressure from the pump. Might that be a thing to consider? Pump speed/press?

 

Its all about fluid flow.
You can change this by changing the valving but you don't want to cause back pressure and burn up the pump.

Here's the catch 22.

You want enough fluid flow to have good feel and power steering at low RPM's like turning in a parking lot, stop sign ect.
Then when your on the highway your RPM's are up so your fluid flow is more which is why the steering gets twitchy and sensitive. The increased fluid flow make the jeep box much easier to turn with less road feel so you're likely to turn the wheel too much.
It has been discussed on here a few times about changing the valves but I haven't heard of anyone acutally doing it sucessfuly.
According to discussions on here...actual Jeeps have an electronic controled valve that changes depending on RPMs to change the fluid flow at low RPM's and high RPM's. Any excess fluid is diverted back to the pump instead of actually changing the pump turning speed. Like a fuel regulator that can constantly change its psi rating with engine RPM. Haven't figured out how to adapt that to our cars yet.
If you go with a KRC power steering pump you can change the output valve size so the pump flows less gpm, the low RPM turns require a tad more effort but it helps desensitize the high RPM turns which btw should only be in emergency situations. You shouldn't be darting left/right on the highway unless your trying to avoid something.
Personally, highway driving is pleasant, you just have to be careful. 90% of the time your turning at low RPM's so the unit is great.

 

Can anyone tell me more about the jeep pump? What year/model jeeps
are these off?

Thanks..

 

Not the pump, it's the steering box.

Read post #5. There are lots and lots of threads discussing the jeep box setup in detail.

 

So there is less road "feel".... so a step backwards if your doing some track time, autocross etc? correct?

Is the Jeep box bigger or smaller then stock? ask because of header clearance issues.

thx

Does anyone know if the Grand Cherokee boxes are modified other than the mounting holes? I have one off a 2004 Grand Cherokee and if it's just making mounting plates & positioning holes, I can do that and save myself about $300.00.

It's also the Pitman arm and the lower shaft that are modified.

 

An old A-body Pitman will fit, the linkage hole might need to be reamed for the correct size.
