Chevi Apache 1958
Hi all, first of all a happy new year to everyone. I own a 1958 Chevi Apache with V8 283 cu inch engine and three on tree transmission. I would like to reduce the engine speed. I guess the easiest way would be to change the rear axle ratio. I searched trough the web but unfortunately cannot find any useful info regarding the OEM axle ratio or what which axle ratio would solve my problem. Thanks in advance and greetings from Switzerland.

Ok, I get it, higher ratio rear end, lower rpm. I don't know what he has in it, or what he wants to do other than lower the engine rpm, but I'd go with a 3.73 myself

I'd say pull the rear cover, and count the gears, that would tell what he has. I'd also suggest if he's wanting to replace it, go with one already built, not try to shim etc. yourself. I was in Geneva last summer, they got some great stuff! I caught a pix of a pre 55 23 window VW bus.

Thanks for your fast feedback. As you might know Geneva is located in the french part of Switzerland. Every year they organize one of the biggest carshows in Europe. But myself I was always more interested in old iron. Could you pls have a look on the kit I found. The owner manual was also a great help. Thanks!

That's fine a 3.38 if that's what you want. You will also, or should consider replacing axle bearings. You also will have to deal with gear mesh which will require shimming the ring gear to the pinon for proper gear mesh. Good luck!
