This question was asked on a local forum and I wanted to know which would be better.
Guy is running 35" boggers. I assumed to suggest the R&P change would be best. Due to the reduced stress on the transfer case and transmission and drive shaft. But others say the 4.7 Transfer case change and keep stock 4.11 gears.

I look at things different because its mostly paper analyzes.

well, 4.7 t-case and 4.11 gears is "supposedly" stronger because the gears are larger than 5.29's

it depends on what he uses the truck for the most? i'm assuming 35" boggers means it's a trail rig or like 80/20 trail/highway

4.7 t-case gears would help to NOT break anything lol

I was assume 80/20 trail and street driving to the trail. I just see the stresses put on the case with those gears. But have not ran them or never been around any one that has trail ridden then either. Thats why i assumed the 5.29's would move the stress point to the axle shafts and pinion, rather than the Tcase.

I run 5.29s on my 85 and I havent had any problems. I put alot of highway miles on it too

it's allll about strength, that t-case can handle A LOT more horspower than anything in that rear axle, and i'd rather break something in the axle instead of the t-case LOL

I seen guys running 37's with ultimate duals on 4.10 dedicated trail rigs without issue.

4.7 w/ 4.10s hands down.

merace19

Well I am convinced. Ya'll say the same as the other forum.

Wab can you add WHY its hands down better?

Because I have driven both and have experienced the difference.

4.7 gears make a lot more difference than 4.10s to 5.29s.

What about breakage? And what difference are you talking about? Take it I have no clue on either and I am just getting the info for later use.

That's a myth: http://www.gearinstalls.com/410suck.htm This example uses 5.71s but the principle is the same.

Lower gearing availability where you can change it is more valuable than a static differential gear.

why would'nt you do both? What wrong with having 529 and the 4.7 gear in the transfer?

That wasn't the question.

cincy85runner

I know its not. but is that a good alternative. and is there any reason that you should'nt do it that way?

I understand sorry, everyone made it sound like that was a bad combo to have for some reason, and that setup is what I'm waiting to install just wanted to make sure I was not making a mistake.

i also run the 5.29s and lower transfer gears no breakage yet but i would start with the transfer

merace19

Well thanks everyone. Straighten me out on what should be done.

myyota85

id say if money was tight then stick with the transfer gears like (wab fab said) but take the build slow and do both.
