Are the axle C's the same for both these axles?

Also, is it less risky to run 35" tires on a Rubi 44 than the standard Dana 30 on other jk's? (If yes can someone tell my why?)

 

yes, they are exactly the same.

yes, running 35's is less risky on a rubi 44 but only because the axle shafts are beefier and the r&p are bigger. but, you'd be okay on a dana 30 too - there are lots of folks running that set up now.

 

The Dana 30 'C's are the same as a Rubi 'C'. A Rubi 44 will handle 35" tires better because the ring and pinion are stronger (larger) and are better able to handle the load. The 44 axle shafts also have a larger diameter inner shafts and larger u-joints.

 

Wow, you guys are quick. That took all of 3 minutes!

Thank you!

 

The D44 is "stouter" than the D30, so in that sense, "yes" it is less risky.

HOWEVER. Your driving habits (skinny pedal attitude) have as much or more to say about "risk" than anything.

Lot's of folks run 35's and even 37's on a D30 and do just fine......

Other's run 35's on a D44 and snap things left and right.

Much also depends on your use. Daily driver, never see a trail? Less risk (in theory)

Trail runner? Love rocks and mud? More risk.

 

Perfectly said. I have run my D30 for 2 years on 35s with 5.13s, open. I have had no issues, but I am smart with the skinny pedal and know my limits.

If you are real aggressive off road, then a D44 would probably be a better choice. You just have to consider the cost issues....
