Here is the first look at the front JL Rubicon Dana 44 ring and pinion compared to a front JK Rubicon Dana 44 R&P.
Both gear sets are 5.38s ratio with a 43-8 tooth count.
The JK R& P on the left and the JL on the right:
JK on the left, JL on the right:
Look at the difference in pinion shank diameters! Wow! and the splined yoke shank is massive too!
The tooth depth is shallower on the new JL gear, however it is a different gear cut, resulting in a longer tooth profile, which should give it more contact and strength.
JK on the bottom, JL on the top:
The teeth are shallower and have a more pronounced curvature of the tooth. This means more tooth contact, which will give more strength.
Lots of interesting changes, we'll update more as we get out the measuring devices and start to spec them out side by side.
