Cardone IROC steering box (pn 276550) ???

I have a '68 with power steering and have read countless threads about converting to an IROC Z steering box for faster ratio turning and a firmer feel. People rave about these boxes and the improvement it will make to your steering. I have read numerous threads also about using the Cardone remanufactured box made for the IROC Z. Cardone's part number 276550. The ratio of these boxes is supposed to be 12.7:1.

I Googled Cardone and the part number and it showed up in stock at the local Advance Auto Parts store so I picked one up. I checked the ratio of the box to be sure it was 12.7:1 and was surprised that it turned out to be 15.1:1.

I returned it and picked up another one from a different Advance Auto. I checked the ratio on this one checked out to be about 14.4. Neither of them near the advertised 12.7:1.

So I am wondering what gives here?........Do I have the wrong box?.......Is Cardone just throwing any gear ratio in these boxes?......Does anyone else double check their ratio before installing one of these?

Another thing I am annoyed at on these boxes is the sloppy paint job on them. Absolutely awful! I don't expect show quality any means but it looks like these were completely assembled including the plugs in the ports and then the entire unit bathed in black paint. The splines of the input and output shafts are clogged with paint. Both boxes must have been boxed before the paint was dry because the paper lining the box it came in was stuck to the steering box. When you tried to pull it off, the paper ripped and fragments stuck to the steering box. The paint is still soft on them and I could scrape fragments off with my fingernail. Nothing that can't fixed but if I was making them, I would be embarrassed to send something out looking like that.

I considered the IROC box upgrade but ultimately went with the one in the link below. Amazing difference in feel. Before, I was constantly steering and moving the wheel especially over every road bump. Now it's smooth as silk. I feel like the suspension is absorbing the road now versus the steering.

I think some of the remanufactures think since the bolt pattern is the same they will all will work for these old cars.
As you found out, that's not the case.
I got lucky with the"IROC" box I picked up from NAPA.

It's a crapshoot. Or spend the $ for a 500 series.

Read my sticky on IROC boxes in the Steering forum. Not all rebuilders put the proper valve in them. The only way to be sure you are getting what you want is an actual IROC box (have it rebuilt, not expensive) or pay the big bucks for the ones like DSE offers

I ordered 2 1988 IROC boxes from O'Reilys and both were the same ratio. Paid $116. Coating was sloppy, no mater most remans are like that. Cleaned it up and shot it with cast majic then with flat Eastwood clear. I was under the impression some years were different. Just a crap shoot I guess. I have had the same experience with ordering the power steering pump. I have had to order another to get the right one. Still a lot cheaper than the after market ones, especially considering the low miles my toys are driven.

The Cardone one I bought has the correct ratio but the valves and setup so you do not get the road feel that you were supposed to. I sent it to Lee power Steering and they went through it and converted it to the right setup. You could just send in your old one to Lee and they could convert yours to this setup.
