Gears? 33's, C4 and 3.50's currently

[rdanford]

Looking into gears for the Bronco...302 EFI motor, 33x12.50's and C4...Currently running stock Dana 44 and Ford 9" with stock open 3.50's. It seems fine currently, the new motor added the power loss from the larger tires. Both the front and rear have 215k miles on them and I know nothing about working on them.

Should I look into 4.11's or just rebuild the current setup? What will the cost look like? Who should do them? Am I missing anything?

Thanks!

Totally interested Dan...Let me know what you want for them, also any advice on install?

[rdanford]

Got yourself a deal on the gears and finding a weekend for the install. Thanks again as always Dan!

Is that a thick front ring gear? If not he's gonna need a new front carrier too.

Just a rule of thumb, be honest with yourself as what tire size you plan to stick with for a long time. There are many gear calculators out there, and you want to target the same drive ratio as you had with stock gearing and tires, maybe even a little lower numerically, to compensate for the heavier tires.

You can look at www.completeoffroad.com and many others to see what gear ratio's are readily available.

Anybody have a used D44 open carrier for the 4.10 gears they want to sell? If not, Tom's has new ones.

If I have mine it's yours. I think Zoso knows where it is so he's gonna rummage around in the garage tomorrow so hopefully he will find it for you.

Awesome...Thanks

Also checked with Melissa at Bronco Hut...she has a used one if you don't have one.

Great thread. I will be moving to 33's in the next few months. I imagine I have the stock 3.50s (I"ll check before I do anything) but is it necessary to go to 4:10s.

most of my driving is around town with occasional short drives to a trail (60 miles).

No plans to go any bigger than 33's

Thanks.

You can always upgrade your tires and see what you think, but with the extra load from larger tires, you work your tranny harder, and your engine, which could overheat both. Plus when adding 33's (and likely a lift) you increase wind drag and yet another factor to making your rig work harder.

However, Shawn, with those ghost flames, you get an extra 25 ponies at least. :)

Found it and Zoso took it to zillas.

I actually dropped from factory 4.10s to 3.50s when I swapped to my 79 Bronco axles. I like it. I drive on the highway and it dropped my rpms @ 65 from 2700 to 2300. I can't pass as easily as before, but I'm not passing tons of folks in my Bronco anyways. But, if I wasn't running a NP435 w/a 6.69:1 first gear I would hate the higher gears. The granny gear makes up for it off road. I get started in 2nd gear around town (similar gear to 3 speed 1st), and its fine. I may have to ride the clutch a little more, but its ok. I'm running 33's.

Yeah, I'll probably try out the 33's for a bit and then go from there. Or I may just keep the 3:50's and paint some more ghost flames!

Maybe a ride in the Porsche

Sounds like a deal
