question about D 30/35 axles

I've got a 01 TJ with the standard D 30/35 axels and am looking to switch to steeper gears. I've got 3.07 and want to go to 4.10 since I have 4 in lift with 35s. Will the stock axels be stong enough for the 4.10?

Also the guy i got a quote from said I may need a larger housing for it? What does he mean by that?

I regeared my 3.07 to 4.10 and run 33's. Still not quite back to stock settings. You will be very sluggish with 35's. Your stock d35 will handle the 35" off road as long as you are VERY VERY careful. Get some 2nd hand shafts now. You will need them. I went through two drivers side shafts before I finally went with the super 35 kit. The Dana 30 is a work horse.

The dana 30 is able to handle up to 4.88 gears so you will not have an issue with the 4.10s if you decide to go that route. If you have 35's I would go higher to 4.88s depending on if you have a manual or auto. Do a search for "dana 30 gears" or "best gear for 35's" and you will get some good info.

I have a good used 4.10 r&p set for a D35 sitting in my garage. They're yours if you need them just pay shipping and some beer. PM me if interested. You will need a bigger carrier for both axles I believe 3.56 and lower is the break over. Dana Spicer ones can be got for around $90 on ebay. I run 33's on 4.10's with a stick and its about perfect for me. 35's may want to be a bit lower.

I went threw this as well, I have the D30/D35 with 3.07s and wanted 35s. I looked into the Super 35 Kit and re-gearing front and rear and it came out to more then what my current set up is. IMO, do not sink any money into the D35, you wiil thank us in the end. Look into a bolt in ready Ford 8.8 with 4.88s or 4.56, (depending on your tranny.) I ran 33s on my D35 for over 4 years, replaced the spiders one, then on 35s for about 4 months, and then starting getting a "popping" sound in the D35, and new I had to upgrade. I went with a HPD30/8.8 with 4.88s for $2,100 shipped from East Coast Gear Supply. I did not get any lockers.

Here is the 8.8 thread, http://www.jeepforum.com/forum/f43/b...8/index12.html

I dunno, The super kit has been superb for me. Easy bolt in install and has performed absolutely flawlessley, so if you ask me it was $800 well spent.

how can you say an unlocked axle is superior to a locked axle?


OP

that should answer your questions.
Unless you live in south Florida 4.10 are going to be marginal at best.

Im not saying that at all. I would have loved to had the lockers put in mine, I just didn't have the extra cash at the time.

The S35 kits is an excellent kit. I had the 3.07s in the D35, so for the $800 plus the cost of re-gearing, it was worth it for me to just have the HPD30 and Ford 8.8 built for the same price. And again, if I have the extra money, I would have had lockers installed.
