Need Gears and advise

[airbornesoldier327]

Well im about to rebiuld my front differential as soon as i get some insite on how i should go about doing it, im running stock gears right now but plan to run 36" irok tires so i know i need to run some different gears. I was thinking that 4:10 would be alright, i mean this is stickly a mud truck, dont really need alot of torque, but i know i cnat run those 36"s im having trouble with the 3:03 gears that are in it now. well i need a set of 4:10 gears front and rear for a corp 12 bolt and a dana 44 front, also i have read in a couple of other places that i might need a installation kit to install new gears... is this right? alright i apreciate the help guys.

yup and then some

You'll prob need new carriers for both axles if your gearing now is 3.03 not sure
, any body will correct me if wrong, but you need carrier that will 3.7 and up numericly. might be cheaper to find a 14bff and d44 out of 3/4 ton w/ 4.10 gears allready. beside that 14bff is tuff.

well to tell you the truth, i dont really have anywhere to work on it and its stickly a mudd truck, so as much as i would love to upgrade the axles and bigger lift and stuff like that, i cant really justify it, i would like to find the parts that i need to do it and take it somewhere and hand him all the parts and tell him what i need done, so at least i can save some on the parts... but other than that, i bought it for 2,500 and i have already put about 3,000-4,000 in it and i still need to get bigger tires, lol... supposed to be saving money while im over here in iraq, but i just cant help myself when i buy stuff for the blazer you know. But if you could tell me where to find the stuff that i need and what exactly i would need that would be great. well i apreciate it.

how much do 14bff's run and what all do you have to do to change them out?

depends on your area.. around here anything over $50 is OVERKILL

hell I even have one under my 8' pickup bed trailer...

I'm running 35"s w/4:11. I would go 4:88 next time around because I have a 700R4 OD trans. Remember, big 1 ton axles sink really good in mud. If your worried about the strength, I wouldnt go bigger than 3/4 ton gear.

I run 38 inch tires on 4.88 gears, w/ OD tranny. Next time I WILL go 5.13. No reason not to if you have OD. My .02 cents. Good luck.

I agree... my non od tranny screams my engine at 3000rpm's doin 74mph
that is with 4.56's... could you imagine if I would have went 5.13's like people kept telling me to go with!!!!!

 

[djsblaze]

I think its kinda funny that alot of people bash the OD trannies. I have Bowtie 700R4 Stage 3, so strength is not a huge concern, though I admit a TH350 or 400 is probably more stout. I just like being able to cruise down the highway, and I do that just fine with 4.88 Next time it will be 5.13s, and then I think I'll be at about perfect. Trial and error I guess...

So is a 14bff a 1 ton axle or a 3/4 ton? And if it is a 1 ton, why is the dana 60 so much more expensive?

The 3/4 ton is a semi-floater with a smaller ring gear (9 1/2" I think. Please correct me if wrong). The housing is smaller and lighter then the full-floater (1 ton, 10 1/2" ring gear).

You won't gain any real strength with a 3/4 ton front axle. The Dana 60 is the only option I know of.

Why?? Because 60's are harder to find and in demand, so............. They go for what people will pay. Keep in mind this is a 1 ton FRONT end.

Sucks for me, I don't enjoy swapin axles in a feild or on a trail.

If somebody wants to donate a 60 it won't hurt my feelings .
