What steering box?

Ok, heres the deal...my 69 needs a new steering box as the orig fast ratio 2.5 turn box started to leak. I have researched back a little, and a lot of you guys have gone with the late model IROC box...easy swap and seems to be met with great results.

But I was looking more towards the 600 series box as this seems to have great reviews, and is a tad smaller, and 5-6lbs less weight. I have tried 2 reman 800 series from Cardone, and they were leakers...argh! Lots of work to R & R with a big block! So I would rather do new, and the 600 box seems really like the way to go, so have any of you guys used the 600 box, and if so how do you like it???

Was thinking of going with the 12.7.1 ratio box from DSE, or Flaming river. NO more reman!

And can someone tell me what front end Alignment specs I should use? Car is not a road race car, and once in awhile will see the drag strip, but all in all is a street car I like to drive.

I heard that Factory specs are not the best... I have stock control arms on for now but over winter or spring will do aftermarket ones, if this matters. Sorry to be long winded, I do hope that I get a lot of feedback on this. Thanks for your time.

Re: What steering box?

DSE, ceramic coated if running headers, is what I have. DSE: quality stuff. I have a very little used quick ratio Z/28 box that was on my 69 for sale. AGR is another product that is quality. Check out DSE ceramic coated-looks great next to ceramic headers.

Re: What steering box?

Hey Dave, so I guess you like your dse box...what ratio do you have? And I guess you have their 600 series box? I dont have ceramic headers, but the coating must last a while.
As I said, 12.7.1 is what they recomended to me, which seems close to my original, but with a lot more road feel to it, at least thats what dse says.

I am more than happy with my AGR steering box. I originally purchased my AGR unit from Summit Racing, as a 12:1 unit. After installing it, and driving it many times, I felt that 12:1 was to twitchy and quick for the street. I called AGR and they agreed with me. I sent the box back, directly to them and they installed a 16:1 variable ratio gear in it and shipped it back to me at NO CHARGE ! They sell this box for the street and they advertise it as 13-16:1 variable ratio. I love the performance of this box and couldn't dream of using that 12:1 on the street. It was a 100% bolt in with no adapters or even a rag joint needed !AGR's customer service alone, was superior.

The 12:1 was VERY responsive. If you sneezed, you would be in the ditch. A very slight move of the wheel and you would be doing a 180* turn. The 16:1 variable is what was used in the later Iroc's etc. The cardone box is basicly the same (16:1 variable) except you won't need any adapter's with the AGR.

Re: What steering box?

I did talk to flaming river on their 600 series box, which is what I prefer, and they said the same box in a 14.1 with 3.5 turns is also avilable too...maybe thats a little more safer??? I do have my factory 2.5 turn box on the car now, and they said its about the same as their 12.1, but their box has more road feel.

Re: What steering box?

I don't think so. I had/have that same stock box, also. It was NOT near as responsive as the 12:1. If I were you I'd go test drive an IROC, not a plain jane Camaro, and see if you like the 14:1 variable.

Re: What steering box?

So then is a late model IROC closer to a 14.1 box, or a 12.1 box? ...I have driven my friends 1987 iroc and i like the way it feels. DSE says their box is a 12.7.1...am i better off with that then say a 12.1 box?...is there that much of a diff between 12.1 and 12.7.1?

I guess what I want is a box thats ain't gonna get me killed if i jerk the wheel...my factory 2.5 box wasnt like that, do you know guys know what that box has for a ratio?, I know its a variable box so it will change as you turn the wheel i believe...

I guess its either the DSE 600 series 12.7.1 box...or a 600 series 14.1

You guys are great and keep the responses comming...I need to get my car on the road again...I just want to make the right choice...and not be dissapointed. So as i said, prob the 12.7.1 , or 14.1...what do you think?
Thank you!

Talking Re: What steering box?

I was told the newer Iroc's had the same gear that I have now. A 16:1 variable ratio. AGR's web site says it is a 13:1-16:1 variable ratio. AGR uses the 12.7:1 as their 12:1.(same gear). If you jerk the wheel on a 12:1 box, you ARE going for a ride.

Re: What steering box?

TJS69, Would you recomend the 14.1 box then...flaming river says its more of a driver box than the 12.1, and has 3.5 turns...and has a nice feel to it. So I would guess the 14.1 is closest to the IROC box? Again, im going with the 600 series box (670 they call it), I didnt think this was going to be such a crazy decision!!!! Thank you for ur help.

If they call theirs a 14:1 ratio, I feel (IMHO) you would be happy with it. Just make sure your PS hoses will bolt directly to it, without adapters. I personally reccomend AGR, but I'm sure others will work.

Re: What steering box?

Yea, I love my box-no pun. It is the dse 600. I have 245 Nittos up front and love the responsiveness and feel, I don't think it is overdone or twitchy.
