1310 UJ's vs 1330 UJ's

Anonymous · Post by **Anonymous** » Tue Dec 14, 10 10:34 pm

Why are 1330 UJ's regarded as being stronger than 1310's when the actual bearing size is the same but the 1330's have only slightly longer cross bit, not width/strength?

is it down to leaverage of the x section?

My loca prop shaft shop guy recons the 1310's will be a stronger UJ?

What HP will a 1310 take and a 1330 joint?

Would of thought the 1310 would be slightly stronger than the 1330 due to being shorter...................... prefer using joints without grease nipples due to the extra strength , never broke a 1350.

Not so much torque being the issue (within reason) , tis weight that will break em.
