Concept One Power Steering Box

7515 Views 35 Replies 13 Participants Last post by  AGVI
Has anyone out there installed the Concept One Power Steering Box in their C3, yet?

I was close to buying the jeep box kit from Corvette Steering, but I like the idea of eliminating those adapter plates. I'm wondering which is easier to install, and which one has more clearance height wise on the inboard side.

Thanks!

Anybody have any more info on this box? I know Witz installed one on his Vette but I never heard how it worked out. Sounds like this may be a good way to go. Here's a link: Concept ONE Performance Steering Gears
Get a hold of Gary - GTR1999 - He is our resident guru on these things. He may be out of town for a day or two though....

I just installed a rebuilt steering box from Gary and it is AWESOME! My '79 steers like new again.:cheers:

He did mine as well.... Steers like a new car. :D
Lower plate on that gearbox is a welded plate to a casting. I kind of cringe at the thought of that section failing. I would like to see more bracing at the lower section of the gearbox, some triangulation or stiffening brackets. I think I will stay with Corvette Steering service's adapter bracket for my changeovers. I like that weld about as much as I like the Steeriods bracket for the rack mount if you know what I mean.

:agree: It may be a fine product but for $995, I think they could have done more. I just saw a picture of an A-body rack and pinion kit. The brackets on that look a lot more substantial than the C3 Steeroids setup.

My $.02. I don't know why the aftermarket cuts corners on brakes and steering products for C3's. You could say it's because we are cheap but the A-body setup I saw was the same price as the C3 Steeroids setup. Being the low cost provider of brakes and steering products is not a good business plan.

Sure it is.....the lowest cost is allways the best.....

That weld is most likely a lot stronger than the cheezy adapter plates and those holes drilled right on the edge of the mounting ears or even intersecting each other. Talk about a backyard way of doing it. I like how they turned down the box and welded on that sleeve. Why would this fail, yet welded axle tubes to a cast solid axle case won't?


As for quality, the fact of the matter is that most aftermarket products (steering in particular) offered for corvettes (C2. C3) are junk compared to what's out there for other cars. For a corvette they use a POS grand am reconditioned rack, yet for msutangs you can buy a proper kit using a very high end and very high quality woodward rack with beautifully crafted tig welded bracketry. Why is there nothing like that available for our cars? The woodward rack on the stangs is a center take off rack too, and it has a PROPER center bracket for locating the tie rod ends, not some flimsy stamped piece that has more resemblance to a tin can than to a suspenion part.

Hey TT, I believe you were involved with a Flaming River rack & pinion install awhile back. Any updates on that? Right now, I'm thinking that and the Concept One are my two best alternatives. However since the Flaming River is a manual setup, I'm wondering how much steering effort is involved.

U do see Marck's pix there don't you.....you think for one second he is concerned about steering effort???

Most are spot welded. :crazy:

Hmmm... You do have a point there. :laughing:
the flaming river install is complete, after a lot of modifying and such. I've seen that someone w/ a white 82?? here has installed it also and didn't have any issues. I posted pics of the install in one of Karstens (mybad79) threads.

The effort isn't even bad, rolling the car aroudn w/ a 502 ramjet up front, it steers very easy
Yes, it's much sturdier and tighter and the best part is, the rack doesn't move w/ the cradle type mount. It's very sturdy.
MY only criticism of the FR rack install I see there is......since they are using 3 joints, why they don't collapse the column like I did to get more angle on the middle joint and relax the upper most joint angle a bit....other than that, and lack of power assist, it's a slick install.....

It's safer without it collapsed.

With all those joints to swing back, it's a moot point.
