26000525 box with a Z cast into it is 2 1/2 turns lock to lock. That's about the quickest one I've seen. Pulled it off of a 86 grand prix v6 car.

Early 90s IROC camaro is a quicker ratio steering box.

Good luck on that in a oem box theres no certain way to id them.

What you need is a 12-1 ratio many sources sell them etc.

instead of spending big money on a new box or even trying to find a use one ,

Can you use a steering quickner? cheeper than a box and easy to install

just a thought

[buterbaughb1]

I used a quickner last year, just didnt like the feel of it, and i junked my factory box (not from the quickner). So i made a bracket that bolts up to the same holes as the quickner. If its too much i can but the quickner right back in. Thanks for the info fellas

I was going to enlighten the above poster to the fact that when you go to ANY parts store, junk yard etc.

And ask for a gm p.s box off a 16" wheel Iroc which comes from the factory with a quicker box... They all REPLACE it with ANY ratio box that will fit...... Which generally is a 14-1 much more common box.

I have been to all the parts stores and went thru all of this years ago and even got a few that swore they could get the right box after ordering in 4 and all of them being 2.5 turns they gave up.

BUT hey maybe youll get lucky once in a while and get a actual direct replacement!!!

Sorry

Actually realized that I counted after on the the car with quickner, the napa part is a correct part number for a faster box I know this because I work there and recently ordered and placed one on my pierce car, which is a metric clip car and it was faster than the used "z" box that was on before.

You probably didnt have the Z box. There is no way to id one that I know about other than counting turns. The casting number on them that ends in 7 or 2 is supposed to designate, but I trusted that for years and two years ago realized my two cars were steering different because that box comes as slow as 3.25...

I also worked for Napa, Super Shops, California Auto and managed a Ford parts department in the past, lol. Trying to get specific parts isnt easy.

That said Harris and I believe Jr motorsports sell a 12-1 box now for 199 or so.
