Default Yet another stupid question

In order to change my Dana 36 with 2.59's in it to 3.73's, do all you change is the ring and pinion or is there more to it than that?

You'll need to change the speedo gear too.

Speedo gear in the tranny? I am assuming. I thought I could just reprogram my prom chip for that? Can I not on a 92?

I just went through this same thing and learned that all dana 36s are NOT created equal. There are two different type carriers...a two series and a three series. If you have a 2.xx ratio rear you have a 2 series carrier and can not simply change the ring and pinion to a 3.xx ratio. To do this you will need a 3 series carrier. BUT, there are some companies who make 3.xx ratio ring and pinion sets to fit in a 2 series carrier. I believe the difference is in the thickness of the ring and pinion sets........ie., a 3.xx ring and pinion set is too thick to fit into a 2 series carrier. It sounds kind of confusing, but bottom line is that if you have a 2.59 rear (like I do) you can't simply change out the ring and pinion set for a 3.07 set-up. It may be cheaper to buy a whole center (pumpkin) section and try to sell your existing one. I'm going through the same exact thing right now.

Yeah, I was pissed to when I learned this since I had a lead on a 3.07 ring and pinion set for $50, but then learned they wouldn't fit :cuss

Well, at least you didn't buy it first, then find out!

I was so close to purchasing a new set from summit, but I thought, I better ask the forum first. Boy am I glad.

This forum is the best, thanks again for the info.

Hey, have you found out anything about changing the speedo yet, or have you gotten that far?
