I am not sure but I think I have heard that 513 gears won't fit into a dana 30? is that correct?

Thanks

 

Yes, they will fit. The carrier has to be changed if you currently have 3.21 but it's a relatively cheap part

 

nice google link... very clever!

 

Yes they can, and from what I understand you do NOT have to get a new carrier, even if you have 3.21 gears. Keep in mind that a 5.13 ring/pinion is going to be somewhat weak in a d30, so if you wheel it or lock it, be careful.

 

yeah, i was wondering that... may just have to eventually build a 44 up with the gears i want

 

ohhh man here we go again!!!

yes u have to replace the carrier with 3.21 gears or install a locker which takes the place of the carrier

yes the 5.13 fits the d30 with zero issues (5.13 in mine for 2 years)

yes the ring and pinion are smaller but the strength difference is negligible. unless u have a 44 or 60 and even those depending how hard u wheel, there is always a chance for breaking the teeth on the ring but its not like every other jeep with 5.13 is breaking the ring

plenty of people have seen just as many failures on all axles d30, d35, d44, d60 that were locked and not locked. if u play hardcore on the d30 then yea u will most likely break it but if u play hard core on a d44 that can break also, but fewer breakages with the d60. alot depends on the tire size thats appropriate for the the axle

 

I currently have 373 gears in mine with 35" tires.

 

3.73 and numerically higher gears (3.73, 4.10, 4.56, 4.88, and so on) you can reuse the stock d30 carrier

by the way is your transmission auto or standard??

imho if you have auto and 35's then 4.88 might be better way to go but some will say go ahead with 5.13

if you have a standard , then 4.56 or 4.88 might be better for you on 35s

but if u plan on upgrading to 37s eventually, then just go ahead with the 5.13

 

You definatly have to get a new carrier if gears are 3:21. I know first hand as I did gears this week.

Auto and 35's you want 5.13's
Manual and 35's you want 488's or 5.13's depending on your driving habits.

4.56's are not available for the JK as far as I Know Nationwide backorder.
