Rubicon U-Joints

[mrchips]

What is the size of the Rubi U-joints and what is the biggest size in strength I can go to 1310/1350?
Who makes a good Pinion Yoke, with a u-bolt set-up 26 spline for the Rubi.
Thanks in advance for any information,

From what I understand, the rubicon uses 1330 u joints and the they are more than adequate for their intended task really no need to upgrade. The flange setup is stronger than any u bolt setup
