I've read that there is a 'sport' higher ratio steering box with 2 1/4 turns lock to lock. I've got a parts car with a box that is 2 turns lock to lock. The one on my driver, which I hadn't checked before, is 2 1/2 turns. I've looked them up and see listings for 2 - 2 1/2 turn and 3 - 3 1/2 turn units. Why do they have such a spread and do I already have the 'sport' ratio? Any opinion on whether going from 2 1/2 to 2 is worth it? I auto-x the car.

Not sure about the 2 2 1/2 turn maybe thats an Rs.. A 3 3 1/2 turn is a Iroc ratio standard gear box. Iroc ratio Is street or Oval. Not sure of auto X...But even a Oval track you can get a better gear box for that also, same as Auto-X.. you just need some one to input with more experience.

The IROC box is 2 1/2 turns lock to lock--or thereabouts.

Base, though I'm unsure how helpful the following info will be, it is interesting, if nothing else:

Here's some general info (I'd like to give credit, but I don't recall where I found the info):

• “WS” – 1982-1992 Camaro – 12.7:1 ratio (just like your Z/28, this may be the box that you Z originally had.

• “XH” – 1985-1992 Camaro – 12.7:1 ratio (this box was also installed on Z/28’s and other high performance Camaros; it has slightly more steering effort required than the WS box.) NOTE – I believe this box was used on cars originally equipped with 16” wheels

• “WN” – 1982-1985 Camaro – 14.1 ratio

• “WP” – 1982-1985 Camaro – 13:1-15:1 variable ratio (used in Berlinettas, least steering effort required of all third gen. Camaro steering boxes)

• “JL” – 1986-1992 Camaro – 14.1 ratio (base Camaro steering box)

If you're interested in autoxing the car, Base, and the steering box is in question, the following link may be helpful:

Can we really use the number of turns, lock-to-lock? Cars with 16" wheels got different internal stops from cars with 15" wheels. Seems to me like that alone would reduce the number of turns, regardless of ratio.

Thanks for the links. When I had the car up to put on track tires I checked and I count 2 turns lock to lock without forcing it. There is a little more each way if I push hard. Anyway it sounds like I already have the fastest stock box available and it's not loose at all. I just wanted a little less turning for some of the tighter turns but not worth shelling out for only a small improvement. And if I get on a road track I may not want faster.

OK Im thinking my 88 G92 package has this box here with the 16" wheel
Now Im going to show you something from rock auto.

• “XH” – 1985-1992 Camaro – 12.7:1 ratio (this box was also installed on Z/28’s and other high performance Camaros; it has slightly more steering effort required than the WS box.) NOTE – I believe this box was used on cars originally equipped with 16” wheels

ACDELCO Part # 360516561 More Info {#88991244} Reman
GEAR,STRG 2 TO 2-1/2 TURNS LOCK TO LOCK; 2 DOORS; w/RIDE & HANDLING SUSP(FE2) or FIRM RIDE & HANDLING SUSP(F41) or IROC-Z PKG(Z28) So seems like this is the box with the suspension package..

ACDELCO Part # 360516530 More Info {#88991227} Reman
GEAR,STRG 3 TO 3 1/2 TURNS LOCK TO LOCK; 2 DOORS; w/o RIDE & HANDLING SUSP(FE2) or FIRM RIDE & HANDLING SUSP(F41) or IROC-Z PKG(Z28) This one here says no Handling suspension..
Now are these Ac delco just as good as our orignals? I see everyone sending there boxes out to places like
LEE MFG. CO.
11661 Pendleton Street
Sun Valley, CA 91352
Ph.(818)768-0371
Fax.(818)768-2687
12.7:1 w/ a 220 valve from Agr from Sweet Ride 45..

My main question is if I order one of these Ac/ delco box is the pitman arm going to fit? Because as I searched for a new one I found two kinds in a 88,, one had a number 7836737 5.. and mine has a 8, So they are very hard to find. Will Rock Auto have this info on there Ac delco. Or should I send mine out to Lee and spend the extra 100.00 that I could spend on a wrong pitman arm. I just want my pitman arm to work. I hit it with a hammer and left some hammer marks on it, I thought I was buying a new one, but that's not so easy. I just want the stock Iroc-Z g92 package ratio gear box with the 16" tires and be able to turn around real quick on a little more than a single lane road an with the power to make the quick rip around turn. And Im guessing sending my unit Lee puts the arm exactly back where it needs to go.. If I bought the ac delco Id be paying a shop to do it an if it's not right an alignment shop would have to do it.. So what do you think James? Send it out to Lee and get what Im looking for an need so there is no mistakes?

Guest

I just called Lee they want 440.00 to rebuild my Iroc-Z gear box. She didnt say why they were so high.. I thought people were getting them for around 220+.. No way could I afford that..

The end cap on my steering box has JL stamped and I saw that it's supposed to be the base "slow" ratio. I looked up some info on a restoration packet from GM that I have and it lists that the LT is a 2.5 lock to lock and it does do a 2.5 lock to lock.

Is is safe to assume that the JL box on my car and other LT's were specifically valved that way for this option package? I read also here on the boards that the "Z" stamped on top of the steering box really doesn't mean it's for a Z28/IROC.

I would to hear from the other LT owners chime in on their lock to lock.

Looks like a nice box. Anyone have one installed already?

Heard AGR boxes were crap, but I cannot personally say that I've tried them. I have a Lee 670 box (the smaller, lighter version of the 800 type boxes that bolts into our cars). It was really good at first, firm, accurate, no slop.. Then about 6 months later there was some looseness and off center feeling which I tried to remedy by turning the screw on top of the box, but became loose again. Lee offered to look at it and fix it for free if it was an internal thing, which is probably is.. I just haven't had the time to remove it and send it to California yet because I've been going through a bad breakup (selling and splitting of house and all that jazz). Camaro has been put on hold since November..

You can have your steering box built to a custom ratio by TurnOne and it will completely change the feel of your Third-Gen.

I paid 550 i think for mine, plus shipping and the exchange rate came out to 680$ canadian.

The average third gen owner would be better off putting that kinda money into their suspension and would see a bigger return on their investment.

If they did all the other mods to their suspension, then a box might be what they are looking for next for improvement in handling. This is all subjective what is better off or not anyway.

I have 2 boxes.

1 is a reman I bought, that was not the "quick ratio". Was listed for fe2 cars, parts store listed "quick ratio" for fe3 or 1le cars. It has no letters stamped on the end cap. It has a large z cast on the top.

I have another box that came of a ws6 car, appeared to be original. It also does not have any letters on the end plate, and has the large z on the top.

Wouldn't the ws6 car have came with the quick ratio?
Why don't these have letters stamped on thr end plate?
What number can I use to Id these?
