hey guys just wondering what i would have to do to run 35s on a D35/30 i want to have a strong set of axles so i would like to know what gears lockers and spline will git-er-dun

The 30 and the turdy 5 are two different animals entirely.. The HP D30 is legit. The 35's just aren't made the same. No reverse cut, low pinion.. Now, you can totally run 35" tires on a D35 but you have to run it pretty gently, which isn't always an option if you get into deeper mud or bigger rocks..

VTJeep nailed it, with 35s the D35 will do if its a pavement queen but offroad its a ticking time bomb where it may last a long time or may last a week as as with everything its will go when its least convenient, the D30HP on the other hand i have seen guys run 38s for a long time on D30HP/F8.8 combos and never had an issue so i would say look for a D44 out of an older XJ or a F8.8 if you want to be able to run 35s without worry

My buddy runs 35" boggers on that combo and beats the hell out of it and doesn't break anything. But other people snap shafts on 31's. It's pretty much hit or miss I think.

I have been beating my open D35 with bias ply 33" swampers for a bit now its already taking its toll. I wouldn't try 35s on it I pulled my pickups 8.8" to go into the Jeep since the pickup is going full width. The D30 can run 35s open on stock shafts. I would recommend some form of beefing the housing if you smack on it though.

Please don't try to wheel 35s on a D35.

The FIRST thing I'd do is make a trip to your PAP. Find a nice disc brake 8.8 from under a Ford Explorer. They're cheap and there's plenty of them. Put that under the back and you can run 35's on it with little modifications. The only thing you have to do is weld leaf spring pads on top of the axle and put some gears in it.

Then, work with the 30. Personally, if I wanted to polish a turd to handle 35's I'd build a truss for it, LCA mini skids, FULL carrier locker (Like detroit), chromo shafts, CTMs, tube seals and a good cover (I'd suggest Ruff Stuff). At the least...

Personally, I'd suggest that you not waste 2000 bucks on the 30 and just build a 44 for half that JUST so you could run lower gears. I run 5.13s on my 35's.

I wouldn't waste my time running anything bigger than 33's until I'd done all of that.

Sure, it may last all stock on 35s. I've seen dumbasses run 38's on a stock D30. I'm not sure why they would want to do that but I ended up driving past them while they're broke in the middle of an obstacle.

Running anything larger than 33's correctly costs time and money. If you don't have the time or money then stick with 33s. If you have time and money then find a better axle to start with.

How much lift do you plan on running with the 35's?

my first thoughts after quite a bit of research was to get a IRO 6.5 3 link on 35x2.5. i already knew that i needed to do forsure one axle swap and put new gears and axle shafts and lockers mostlikely arb or e lockers becuase i have a np242 i have to run a hack and tap SYE fro what i know. once i get dana 44 and or a chrysler 8.25 ooorr a ford 8.8 could you tell me the best gears and lockers what add ons do i need for two of the three axles.

I think the S35 is highly under-rated, albeit expensive.

You can run 35's on the 30/35, it's just not that practical due to cost compared to other axles.

i would never take a d35 out on 35's and actually beat on it.

everything in the d35 is tiny, the shafts only measure out to a 1.12", the ring gear is tiny, pinion is tiny, housing is tiny, spiders are a well known weak spot.


if you want to run 35's on a real tight budget, then just toss in a 29spline 8.25.

I wouldnt run 35s on a 35 on a front 30 yes i would but a 35 no ive broken 3 shafts on 31s you can find a 97+ c8.25 theyre 29 spline and direct bolt in and willl handle 35s some people to get lucky though my friend ran 38.5 on his YJ 30 /35 axles wheeled it and never broke had a lunchbox locker no truss stock shafts dont no how

LaredoLover8

thanks man if i can find a dana 44 before a 8.25 would that be better once i put new gears locker and shafts

Thedude

a buddy of mine runs 35's on his d30/d35 combo and does very well. They're still geared at 3.73 and have no extra work done to them. He's had this set up for well over a year, goes harder than i do and hasn't broken anything. so it COULD be done, but it's better to be safe than sorry

They're about the same strength. Aftermarket for the 44 is much better, but paying for the 44 is where it gets you. Unless you find a deal.

Skunkape

35s on a 29 spline 8.25?The rumour is its comparable in strength to the 44.Works for me and a buncha others

LaredoLover8

If i cant find one or want to pay for one iol just go for a ford 8.8 there are lots fif them there almost a strait dropin just an inch short.
