Corp 14 Factory Gears

Did the 14 ever come with gear in the 3's. I want to replace the old 10 bolt with a 3/4 ton 14 bolt with gears in the 3's to keep fuel milege on the resonable side. I plan on running the 35x10.50/16 SSR when they come out. So a 3.73 should be pretty decent.

If it aint broke, keep fixing it till it is.

Re: Corp 14 Factory Gears

As far as I know(which aint very far)[img]/wwwthreads_images/icons/smile.gif[/img] They did(14 bolt axles) come with 3.73s but if you're running anything more than a 33" tire 4.10s or 4.56s would be better.

Just remember that if your motor is not operating in it's intended power band that you'll suffer in mileage department.

Re: Corp 14 Factory Gears

The 14 bolt full floater generally came with 3.73 or 4.11's. I had factory (1980) 3.23 gearing in my FF and I have seen 3.42's from factory and aftermarket. With what you are running these are too high (low numerically). You would want a lower gear (higher numerically). Without Overdrive I would go 4.10-4.11 and with Overdrive I would go with 4.56's. If you go with 4.56 you have to get the Thick ring gear to compensate for the case split, or get regular gears and a 4.56+ carrier. The thick ring gear is the cheaper way to go, and most people say it is just as strong a setup.

If you didn't built it yourself, how can you call it yours.......
