Hey Guys, I am a noob and have been doing a ton of reading here. Lots of great info. I know the d30 and 35" tire thing has been beaten to death and I've read everything I could on it.

I wanted to do a poll to see real world experiences with this set up. Have you done it? Have you done any axle reinforcement? (sleeves, gussets, chromoly shafts, rcv shafts, etc...) Gearing? Lockers? Have you had any problems? What problems? What kind of use do you put it through?

I am getting lifted soon with 35's, 4.88 gears (6 speed manual), evo sleeve, evo upper and lower gussets, lca skid.... debating chromoly shaft. I know the best scenario would be to upgrade the entire axle but unfortunately out of the question at the moment.

Would love to hear what everyone's experience with this is.

Thanks!

 

If you are not swapping to a 44, my opinion would be to upgrade the housing as far as your budget will allow - but leave the stock shafts in. I would rather replace a shaft than destroy the gears.



To answer the 'have you done it'.
I bent my 30 running 33's mostly onroad, just a few light trails. No gussets/sleeves, and no stupidity in the rocks or anything.
You will find that a lot of people are not having any issues at all. (or they don't know that they have issues. Yet).
And you will also find people in bone stock rigs shattering their housings on-road. And you will find people with gussets that are still bending the C's, and people with sleeves that are still shattering the housings.
How lucky do you feel?

And maybe some old polls asking the same thing would help...

Thanks for the link. Didn't see that one.

 

Put gussets on it, run it till it breaks, then upgrade to a prorock.

 

I wheel my dana 30 pretty hard, It has an electric locker, which I try and only use when wheels are not cranked hard one way or the other, sometimes unavoidable, so far so good. Also have 5.13's installed so I'm into the axle pretty deep money wise. I'm still running stock axles. I think I've been lucky so far. I think I will weld on outer c supports and upgrade shafts and see what happens.

 

got the evo kit and stock axles shafts
no issues.

 

All I have is evo gussets and I run 35's and 37's. With stock shafts no problems yet

 

The reinforcement is for the axle housing rather the "axle". The 30 ring gear is smaller than the 44 but if your not planning anything to extreme am are light on te skinny u will be just fine

 

I just added 5.13s,TF gussets to my D30, but I ran a stock D30 with 373s for 2 years with 35's and numerous wheeling trips and didnt bust anything but 2 power steering pumps. When my mech was adding the gussets he said my C's were fine. Just don't gun it everywhere and you will be good.

 

I am in the same scenario. I am changing tire plans due to still keeping the d30. nitto trail grapplers @ 80lbs 35x12/17 down to Duratracs @ 63lbs 315/70r17.. And I will be installing the evo gussets as well..

Specs to be installed yukon gears 4.88 w/new front carrier and EVO gussets. David @ Northridge has yet to steer me wrong.
