Super 35 Upgrade

Is it true that the super 35 upgrade for your axle would be stronger than the D44 im trying to go the cheapest route until later when i will eventually get new axles. will it hold up to 35" tires if i wanted it to?

I don't know where it ranks in terms of strength against a D44 but It is supposed to be good up to 35" tires no problem.

Yes a Superior Axle Super 35 Kit is stronger than a stock D44. Yes it will handle 35" tires but nothing bigger. This is the easiest axle upgrade for a TJ. Not necassarily the least expensive. You always have to figure the cost of regearing the front as well. I did mine for around $2300. That included the S35 kit w/ DL and 4.56 gears for front(4.55) and rear. All new bearings, seals, brakes, u-joints.

Technically it's only the axle shafts from a Super 35 that are stronger than a stock Dana 44. The Super 35 shafts are hardened alloy 30 spline shafts, the OE Dana 44 are standard carbon steel 30 spline shafts. The D44 gears are still stronger but a Super 35 equipped Dana 35 is certainly up to handling 35" tires and its locker on even a very tough trail. You won't really have to worry about your Dana 35c after installing the Super 35 so long as you stick with 35" tires and don't just absolutely try to beat the snot out of it.

P.S. My comments only relate to the Super 35 kit made by Superior Axle, who first developed the Super 35 kit. Since they did not copyright the Super 35 name, there are lots of imitators out there who "stole" the Super 35 name but not all of them are up to snuff. So be wary of lower quality imitators, a "Super 35" kit is not necessarily a real Super 35 kit. But if you stick with Superior Axle you'll be fine.

Would it be reccomended to "truss" the d35 in combination with the superior super 35 kit. Or would it beneficial to just take that money and do a 44 or 8.8 axle.

Yes I looked around. Jerry B actually put me onto Savvy Offroad. They where the cheapest. Talk to Gerald at Savvy.

At the end of the day its still a dana 35 I would never invest a dime into one. the tubes are still weak the ring gear is still small. Its just a POS axle. find a dana 44 or an 8.8 and build that up or if your really into wheeling find a 9/60/14 bolt and build that up

Those are all childs play...you are only serious if you are running 2.5 Rockwell axles.

The TJ's Dana 35c uses the exact (!) same axle tube that the TJ's Dana 44 does, they are cut from the same tube stock. Ad even out in the Hammers trails in Johnson Valley where some run them, they do fine. I personally know several running them. Other stuff breaks but of the couple guys I know running Super 35 kits with 35" tires in Johnson Valley, they've broken lots of stuff on their Jeeps but not their Super 35 rear axles.

So when you do the super 35 on the rear what do you do to the front? I have a 97 TJ and I believe it's 35 in rear and 30 in front, besides changing the gear in the front is something else I can do? I'm wanting to run 35" tires also...

The D30 is capable of running 35" tires. You would only need to regear the front. Superior also makes a kit for the D30 but that is up to you.

Any idea the cost of the kit/install? Does it always require regearing?

Once you get to 35" tires and have a front-mounted locker, a good upgrade I'd strongly suggest is a set of hardened alloy axle shafts for the front axle. I broke my passenger-side front axle shaft years ago on Sledgehammer but upgrading the front shafts to hardened alloy 27 spline shafts stopped further breakages. I stayed with the Spicer 5-760x u-joint for that setup and never had another breakage. Hardened alloy 27 spline shafts are plenty strong for 35" tires and a locker doing trails even like Sledgehammer. Superior Axle makes a nice set of 27 spline hardened alloy shafts called the Evolution Series.

cv axles from rcv performance I believe are the best dana 30 choice. Lifetime guarantee, they say its the last axle you will ever buy. Not much more than chromoly axles that do break quite often.

HPD30 is another awesome upgrade for the front. You can pull a HPD30 out of a Cherokee for super cheap. Direct swap, everything from your LP D30 swaps can be swapped over, except the R&P, but since you are re gearing anyway it doesn't matter. Plus if you find a Cherokee with higher (numerical) gears you won't need a new carrier or have to mess with thick cut gears.

What years models of Cherokee are best for the hpd axles.

I beg your pardon? Chromolly axles break "quite often"? I don't think so. Come out to my neck of the woods and watch how they do on the types of trails I enjoy.

P.S. What kind of steel do you think those CV axle shafts from RCV Performance are made out of? I'll give you a hint... chromolly steel.

Anything '92+ will work. If you want to pull an axle and use the shafts look for '95+ because they came with the better 297x u joints.

yes they are but i have seen alot of stock type axles break even if you have a dana 44 because the outer stub is the same as a dana 30. If you are running 33's or smaller it usually doesn't matter. If you want bigger tires you better upgrade or you will break you stock style chrome moly axles.

The big difference is the joint and ears where it mounts, thats what breaks quite often.

The ears that hold the u-joints on the OE (factory) carbon steel shafts are known to stretch and fail, it happened to me and I have broken them plus an axle shaft on Sledgehammer in Johnson Valley.

However, the u-joint ears are NOT known to stretch and fail on hardened chromolly shafts like the Evolution Series axle shafts from Superior Axle. I haven't had a single stretched/failed axleshaft ear/u-joint since switching to hardened alloy axle shafts on my previous Jeep (Warn axle shafts) and present Jeep (Superior Axle shafts). When RCV talks about the ears failing, they are referring to the OE factory unhardened carbon steel OE axle shaft where that is a problem.

And I woud have to suggest that the rock crawling trails out here in the deserts of SOCAL and Johnson Valley are about as tough as you'll find. Axle shaft breakages there are rare once you upgrade to hardened chromolly shafts from companies like Superior Axle. Do I dare ask if you have personal ownership experience with any type of hardened aftermarket axle shafts yourself besides what you have read? Like do you personally have an RCV or any other aftermarket hardened axle shaft installed in your Jeep?

I dont have either sets of axles yet. Some of the guys that I go wheelin with have had chromoly and stock and two have crv axles now because of breaking regular chromoly axles. The joint usually fails which in turn causes damage to the ears on shafts. I was just saying if you are going to spend 600 dollars any way for chromoly put 400 more with it and you dont have to buy another axle ever. you break it, they replace it.

Only 400 dollars more. You could buy a lot of other things with 400 dollars...

If your spending 600 dollars on shafts, another 400 dollars for RCV shafts is almost a 70% increase of 600 bucks.
