Pros and cons 1310 vs 1350 yoke

[Musician235]

In the process of ordering an SSSYE / Driveshaft and have read some of the perspectives on 1310 vs 1350.

I am always inclined to overbuild and go with the beefier components (wanting to go with 1350) but am wondering if there is a major drawback to going with the 1350 for a stock SE.

Should I stick with the 1310 to keep a "weak link" so as to have it be the point of failure in a pinch? Is having the straps there to break a better fail safe measure to protect more expensive components that would break if the yoke/straps didn't break?

This is a DD vehicle not a rock crawler. Thanks for any insights.

1310 is overbuilt for a Tj.

A smaller joint width (width across the entire joint, not trunion size) creates less torsional vibration, so I would go with the smallest joint that's strong enough.

I don't hear about a lot of TJ driveshafts failing at the u-joint. It's usually dropping the rigs weight on a rock with the shaft bearing the weight and destroying the tube. Actual joint failures seem to be mostly normal wear or complete lack of maintenance. The driveshaft sees a small fraction of the torque put through the axle shafts, and those usually only fail during abuse at extreme angles.

1310 size u-joints is what the TJ (non-Rubicon) came with.

1350 is oversize for a TJ for even most very aggressively built TJs. 1350 size u-joints are also big enough to restrict droop. I stupidly went against Tom Wood's recommendations for 1330 size u-joints for a new rear driveshaft years ago after recent trail breakage and I insisted on 1350 u-joints. After changing my yokes to 1350 and installing the new driveshaft I took it wheeling and right away knew I had screwed up by insisting on 1350. At full droop on a fairly tough trail it sounded like a machine gun in the back of my TJ while the u-joint/yokes banged into each other when rotating from their size being too large for my needs/configuration. I replaced that driveshaft with one with all 5-1330x u-joints, eventually in the front too, and never looked back.
