Superior Axle 30 spline upgrade for D35

i was wondering if the 30 spine upgrade from the 27 requires anything besides taking out the old and putting in the new? i heard somewhere that the axles needed to b machined out?

Your spider gears need to match the spline count on your axle shafts. This now makes the ring gear and carrier the weak point in your rear end. I'd keep the stock shafts unless you're upgrading the carrier too. Axle shafts on a dana35 are like a fuse. They blow before you damage something more expensive to fix.

You can't get a 30 spline carrier, you have to get a selectable locker for the application, ie. ARB or OX.

IMHO, you'd be much better off and less money getting an 8.8.

Ya iv Ben thinking about the 8.8 but.. I can't really shorten that much at once. For my tires I had to buy two at a time cuz of money. I'm 19 and all my money is going into my jeep. But I am planning on doing the entire super35 kit.. I'm Judy going to buy the locker at a separate time as the shafts. Plus if I did do the 8.8 I would have to buy new wheels. And I just bought songs and had them all powdercoted..

why do you think that?


from a fiscal perspective the super 35 kit is a waste of your money.

You would not have to buy new wheels with the exploder 8.8. That is one of the main reasons they are a good deal.

I would do alot more research into the 8.8 because it seems you dont fully understand the concept.

Super 35 Kit is roughly $1500 when all said and done. You may get the strongest D35 you can out of it but it is still however a D35 and its not uncommon to hear of them breaking.

I bought my F8.8 from a junkyard completely intact for $65. This include brake hardware, Ebrake lines, 4.10 gears (upgrade) and a Limited Slip. Mounting kit and bulletproof differential cover costs me roughly $200. I drop in a 4 cylinder (4.10) dana 30 upfront and I have upgraded my gearing, brakes, and my axle is roughly twice as strong. If i decide to go bigger then 35's I can still upgrade the unit with a super 8.8 kit and a detroit and laugh at 37's. So for Substantially less money you get far far more with the 8.8 IMO.

Anyone have the link to the thread where the guy argued and argued about his super 35 then it blew up the first day he wheeled it? It had something to do with humble pie if I recall.

Yeah def don't waste your money on the super 35. Go for the 8.8. You'll spend just as much money as you would on a super 35 and you get a much better axle.

I think any model will do they all have 31 splined 8.8s. But most desired is 96-02 cause of the disc brakes. Correct me jeepers if i got my explorer yrs wrong ha. the 8.8 have the same bolt pattern as jeep so no new wheels. The axle is slightly narrow than the d35 but hardly noticable. There are ways to add width to it if it bothers you. A stock 8.8 can hold up to 36" tires. arguably 37"s but not recommended. A super 88 kit added then the 8.8 will run 37s all day. I still run d35 with 33s no issues yet but will be buying a 8.8 in the future and seems they are hottest jeep mod these days too ha

If you''re upgrading to a duper35, then you must be planning on using it hard core. Also keep in mind you can still bend an 'ever so weak' turdy 5 axle tube even with the duper kit. It is just not worth it IMHO.

btw... exploder years are, '91-94=drum, '95-01=disc. All have 31 spline shafts.
