33's and D35??

Hey all. I'm looking to go with 33's but don't have the $$ and time for an 8.8 conversion at the moment. I don't do a lot of heavy wheeling but I have a tendency to take a left off the pavement now and then. I've heard a few different outlooks on it like no to 33's with the d35 and also have heard from friends in Colorado that have had no issues that wheel regularly. Looking for some of your input from experience. Thanks in advance.

This thing was babied. Only had 105K on the odometer when I picked it up. The PO only put 600 miles on it from years 2008 to 2013... crazy right?? They took it to the beach now and then and took care of it, all fluids and regular maintenance was done to it. The only major problem was rear frame rot, but that's been taken care of since I got it. Even had BRAND NEW rims and 31/10.5 General AT2's on it. Looking for a little taller tire and something a little more aggressive like BFG's KM2's plus I can get those in a 33/10.5 instead of going wider with a 12.5. I'll be doing the 8.8 conversion at a later date though.

I have run 33's on a Dana 35 for about 4 years without a problem. They aren't the greatest axle, and as long as you keep that in mind, you shouldn't have a problem with it.

If you want to get stupid with it and do a burn out on pavement to "impress" the crowd, then you will have issues. But as far as back roads or trails that only occasionally need 4wd, then I wouldn't be worried about it.

I swapped to the 8.8, cause that was the thing to do for an upgrade, my 35 went out while I was turning into my driveway. No stress, no torque, just "pop" say good night Irene.

Thank's guys. No burnouts planned OIIIO, just some wheelin now n then. It's my DD for now till I get another rig and then I'll either build this one or the other, but that's not gonna happen any time soon unless I get a smokin deal on another one. Plus I have other things I'm getting for it like new suspension, MC2150 carb, front n rear bumpers and some 33's.

I've grenaded 2 D35's with 33's but both times it was caused by needing to bump up a ledge the shock snapped the shafts. And that was behind a 2.5L also locked. I'm already looking for an 8.8 for my current YJ

33s on a Dana 35 - alot of them break and alot of them survive. It's a risk.

I replaced mine with an 8.8. I didn't want to be trailering my Jeep home after breaking an axle when offroading. That sounds like a horrible PITA for me and the friends that I wheel with.

I'd personally recommend you place it higher on your Jeep upgrade list. If you can't afford an 8.8, can you afford the potential recovery and towing fees?

Hi;
I'm clueless but interested in learning. I just put 33" tires on my 95 YJ to get through the deep snow. It works so far up to 18". As far as I know the drivetrain is stock. So what are the Dana 35 and the 8.8 referred to above and what is the difference. It looks like the 8.8 is preferred. Have pity....

d35 and 8.8 is refering to different rear ends..if stock then your jeep has a dana 35(d35)..the 8.8 is a ford rearend like used in the ford explorer.The 8.8 is a popular swap into jeeps because it is narrow like a jeep axle but a lot stronger

I need to replace springs first, one leaf broke in the rear (original leafs), plus I gotta get rid of the 2.5" lift shackles that are on there...(garbage). So like I said, I'm spending $$ on correct lift kit and new shackles. Also as mentioned, Tom n Stan, I need a carb too so limited budget for now and I can't have my rig down for more than a day at a time as it's currently my DD so time is more of an issue. Plus I know well enough not to lock a d35, seen what happens to those especially with stock axle shafts.

Thanks Harleydragon. I went back and looked at StanF's installation of the 8.8. I get it now. Something I could do I think. Much appreciated.

I broke the 35 in my first 95 YJ by doing a 2nd gear powershift. This was with 31's on pavement. Barked the tires like a big dog, but that was the end of that particular D35. (1998 time frame). The center section pretty much broke into two pieces. It should be noted prior to that I had worked that rear end over pretty good. Me & the boys blazed a lot of trails back in the day with that Jeep. The stories are still told to this day. lol.

Fast forward 16 years. I'm older & smarter these days. My current 35 should last a long time given the way I drive the Jeep & what I use it for, even with 33's. If & when it blows up, I'll do a 8.8 swap but not before.

Bottom line is, yes the 35 gets weak with oversized tires. But if you use your head & don't get too crazy it should last. I agree with you, I would never lock a 35. You've pretty much signed its death warrant by doing so unless you've done some serious upgrades.

If you are going to do 33s with a D35 I would suggest getting a spare axle shaft. It could be a life saver off road. Safe you a lot of money it getting it home. They aren't that hard to change. But I would suggest changing your rear diff fluid and going through the process of removing the center pin and c-clip in your garage so you aren't experimenting on the trail.

Good suggestion...but don't forget a drain pan, gear oil, RTV, gasket scraper, rags, tools, fill pump, etc.

Thanks Thomas S. I used to wrench for a living as an A.S.E certified technician so I'm familiar with pullin a rear diff apart. Of course I don't know if that's a good thing or a bad thing lol.

X2 on the spare axle shaft(s). Remember that the D35 has different length shafts on each side. Murphys Law dictates that if you only carry one axle, the other side will break! Thats one reason that I went with a 29 spline 8.25 axle when I finally swapped mine (same axle on both sides!).

Ive got 33s on my 4.0 94 with the d35. Its my dd because my four door ford diesel is lifted with 35s and is a bit thirsty. Ive learned from these forums, which i have dubbed " The Bible to all things Jeep", that the long pedal is the nemesis on that joke of a rear end and its not if its where its going to give. Take what these guys say as the the gospel truth because almost all their info is from experience. If you stay with the 35 for now baby it until you can beef it up. JMO

Everything that's been said it's spot on. I've been running 33's on a Dana 35 for the past year or so and have been lucky thus far. Currently looking for an 8.8 to swap in.

On my first YJ, I ran 33s for 4 years and the PO had 33s on it for who knows how long. I ran that thing hard on trails, in mud, and on the pavement. Even jumped it a couple of times.. Never had an issue with the Dturdy5.

In fact this was with a brand new set of Mickey T Baja Claws.. had to break them in ya know.
sorry for the crappy quality.. cell phones used to not take such great videos years ago lol

I drove my jeep on 33s with my dana35 for well over a decade...


...before I broke my pinion teeth and swapped in an 8.8. YMMV.


To be fair, I never changed the fluids, deep forded and didn't play nice.. So I was impressed it lasted that long.

A heavy foot can break anything. I weld the spider gears on every Dana 35 I have had for a wheeling rig and have run 33's-35's. I have never had one "explode" like people say.
I personally feel that have a traction aid is better on the axles if one has common sense because you don't have to use rpms to get though something. You can just crawl
If you bounce much it will break, so will the bigger, stronger axles.

IMO the Dana35 isn't worth putting a lot of money into such as upgrading the axle shafts etc. 8.8's are way too cheap.
That being said, I have recently changed mine to an 8.8 and geared 4.88 for the 37's and 4.0 I plan to install very soon.
