I am thinking of changing the steerring box on my 89 RS with one off of a WS6 firebird....Is it worth it to do, if I get it dirt cheap??? How exactly will this change the way the car drives...I know this sounds kinda silly, but I have never experimented with different ratio's on the steering???? Any of you guyd dones this swap??? Pros'??? Con's???? Thanks alot, Tom

 

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)

This probably helps with the answer to my thread. Was the JL box used 82-92 as the base box? Is the radius listed the amount of times you turn the steering wheel?

 

See my edit.

So that means there will be a difference in the car's turning radius between the base box and the quick ratio box? I don't know what year it's off of and I don't have it yet, all I know is the seller said it had no play and is 2 1/3 turns lock to lock.

 

Well mine is an RS, not a Z-28 (I wish) Would it be worth the effort to change it???I dont care if its a little harder to turn, if it gives me more road feel so to speak...What do ya think guys, yah, or nah?????? BTW, ive already done the wonder bar, and 17 inch tires, new ball joints, and idler arm. wheel bearings, brakes.Am fixxing to do the sway bar bushings.... Thanks, Tom

 

The above info is part of a document that I can't readily copy and paste. If you'd like the doc in its entirety (though I'm not sure how much it will help), provide an email address and I'll send it to you as an attachment. Never mind. It's in the following link:
