You can play with fire if you want, and you might get away with it, but the more you play with fire, the more likely you are to get burned.
42s on a d30 is a whole lot of fire, and a whole lot of playing around with it. :dunce:

33's is the best tire size. the move to 35's usually dictates building axles. 33's can live on a stock d30 as long as you're not a moron.
an AW4 is probably the most durable overdrive auto trans on the planet. Seriously, I hate all things auto trans and I have respect for the abuse an AW4 can take and not even flinch. That said, heat kills fluid, and crap fluid takes out the clutches. No way around that. Torque converters make an extraordinary amount of heat when they do their thing, and with stock gears on 33's its gonna slip a ton.
The only good thing about 4.10s is that you can find them in junkyard axles. Otherwise, 4.56 all day long. Don't be afraid to run a 4.0 at 2500+ rpm on the highway. The lower gears will mean sooner converter lockup and less unlocking on hills. The more a torque converter stays locked the less heat, the less heat the longer your trans is going to live.

I have done ungodly things to AW4s without killing them. Possibly one of the most bulletproof autos I've ever run.
Probably because it's (iirc) rated for 450 foot pounds torque when our engine only produces 235.
Toyota uses the same tranny with a different bell/torque converter/tailshaft/output housing/a few other changes behind their 4.7L V8 in the Tundra. And basically in every other RWD Toyota ever. They call it the A340 and it's bulletproof in those too.
dana 30s? IMO don't go over 33s. Maybe 35s if you're in Moab and can crawl everything. Muskeg or what we have out east, which is rock gardens, but with moss and mud and trees mixed in? Don't even think about it, 33s max.

If your ragging on Swampers then you have obviously never run them before. They are built for one thing, mud, and they do that exceptionally well. Hands down no other tire is going to do better in the mud. The only thing that will come close are ag tires, and that's a completely different animal.
I understand that professional offroad racers like Ultra4 don't run them, but that is because they are not race tires. However the guys at TTC are running boggers and I would say they have enough experience to qualify as professionals.
Give credit where credit is due. Interco Tire, or Swampers, makes a damn good mud tire that has stood the test of time.
FWIW I am running BFG KM2s 33s on stock HPD30 and 8.25. Been running it for over a year and have yet to break anything. My experience from Swampers comes from the 39.5 TSLs that I ran on a 93 Bronco locked with ARBs on both ends and a Ford Racing 351 under the hood.

Disagree.
It all depends on ur riding style and what ur riding. Being in Tennessee I won't run anything but a TSL on my trail rigs. I've ran red labels and maxis treps and still came back to the TSL. IMO a TSL is the best all around tire considering how they dig on dirt, mud, n creek beds, price compared to other tires, side wall reliability, etc.
With that said, sure you can spend a wallet size load more cash on red labels or treps, but in the tennessee mud and muck they just didn't give me the handling and drivability I wanted. They def kicked ass on the rocks.
Of course if we're talking 33-35 you can't get red labels in those anyways. I think they make creepies that small, but still don't compare to a good ole fashion TSL or TSL sx around here.
To each their own...

Agreed.
The AW4 is no weak point. I have rarely heard of them going out even on trail rigs with 250k on them. You've got guys running them in 400hp Supras running the hell out of their cars with no issues.
I ran 35 bfg mud terrains on my silver xj for about a year. We don't just ride logging roads and that crap, we wheel hard crush beers bounce into trees and break parts. With an open 30 on those 35s and 4.56's I wen about 6 months before exploding my front and going to a 44. If logging roads and moderate trails are all you ride, I don't see any reason why 35s on a stock 30 wouldn't last you a few years if longer. You may never have an issue if that's the type of riding you do.

Based on some of the haggard hillrod fab I see in some of those rides, I'm going to have to disagree with this.
The rest of your post however was fairly on the mark. I have no opinion on boggers/etc as I have never run them.

I have to agree with kat stain on the TTC guys. A great event to watch, always a good show ..... not professionals.
On the AW4 a great trans yes, but not a 400+ HP trans as guys claim. Last year we took the Ultra4 stock class series championship in an XJ with just shy of 400 horsepower, and basically went through an AW4 every race. More than once we came over the finish line with no 2nd gear and at half throttle just hoping to make it there. We think we have the right combination of upgrade and aftermarket parts now to make it hold up .. but time will tell.

The only swampers worth anything are stickies.....otherwise the only thing worse than swampers are Falcons
surprisingly the falcon wildpeaks do better in the mud than our mtr/k's did..

We're running 5.38's, so I wouldnt expect the size of the 35's to be a big effect on the trans. I think its more the torque converter has a hard time with shockloading (disabling lockup permanently helped) and the higher RPM's into the pump overpressure the solenoids and they pop open at the wrong times, causing eradic problems.
We did strait up burn one up, but to its credit our transmission cooler fan failed .. on the starting line! .. we raced the entire king of the hammers with effectively no cooling. It finished the race with our fingers crossed, but then failed giving some press guys a ride the next morning.
