dana 60 or 14bolt for 36's

[cheapcherokee89]

debating on whether to use a dana 60 or a 14bolt in the rear of a zj with running 36 inch tsl's. i have a 60 but it has the 30 spline shafts and dont really want to upgrade it to 35. however the 14bolt yet while stronger is going to really kill ground clearance. Is the stock 30 spline 60 shafts strong enough to hold up to the 36's and what about with chromoly shafts? jeep has the 4.0 and is a automatic

With a 4.0/auto you should be fine with stock 30spline shafts. You can pick up chromoly 30 spline shafts for about $250 new last time I checked. Thats what I did, but I don't even carry the stockers for spares. I'm running a 4.6 stroker, 5.61 1st gear, 4:1 t-case, and 4.56 axle gearing, going into 36" TSLs, and the jeep weighs 5200lbs.

with the stock 30 spline shafts, you are probably okay up through 37s and possibly 38s depending on driving style.

and then there was a guy on jeepforum who had 42s on stock 30 splines and never broke them...but I think that is the exception to the rule.

with 36s, that 14b will probably take up a lot of ground clearance. these guys here talked me into a 14 bolt, though, however I am going with 37s/38s.

If 36s is what you are sticking with, 30 spline is fine!

just so ya'll know a little more, HE HAS AN EXTREMELY HEAVY RIGHT FOOT

 

[cheapcherokee89]

you must have me confused with someone else

 

[backntac]

is it a FF or SF that makes a big diff

 

[cheapcherokee89]

The way you drive Josh you might want to look into Rockwells.

 

[toyotaman84]

most 14 bolts are 30 spline. just an fyi

yeah but it's FF 1.5" dia. shaft 30 spline.

the dana 60 FF is like 1.3" dia. shaft
(approximately)

 

[cheapcherokee89]

well looks like im using the 60. we'll see if the right foot gets the best of it and go from there

 

[wranglerrambler]

hell yeah

I think there now needs to be a poll on how quick he breaks it

I think the Dana 60 will be fine, but put a 14 bolt and be fine when you upgrade to 40+. You can shave the 14 bolt pretty good also.

sticking with 36's already been down the road of upgrading to larger tires on a different rig. Swore after that i would stick with 36s next time

You'll sell it before you ever wear the tits off of the 36's.

how come?

 

[GubNi]

how come?

I bet it's cost. bigger tires = bigger axles = bigger money

 

[cheapcherokee89]

gubni your mostly right. but also drivability. i want to be able to drive it the 3 hours to the beach or to work , or whereever my heart desires without it being a job...if that makes since

I run 42x15s on my CJ and have only broke on d60 rear shaft in probably 20 trips. It runs an AMC 360 mildly built and 7.17 diff gears. and yes 7.17 is too low but is nice when the carb is screwing up.

 

[on the rocks]

Go with the 14bolt and shave it. It won't be much bigger and its stronger than the 60.
