Yukon 4.88 Gears Question
A guy I work with has given me a set of 4.88 gears for my JK Sport that I'm bout to make payments on to him but had a concern that someone may be able to answer for me.
1. For my JK Sport with the Dana 30 and Dana 44, will a "Short Reverse Pinion" work in the Dana 30 and will "JK Rubicon" work for the Dana 44?
I run 35s on a 4.5 lift. Any info will help

Are the gears from a jeep JK? And from a non-rubicon?
If so, they will work. If they are not from a JK, they will not work. If they are from a JK rubicon, the rears will work, the fronts won't.

The rear 44 gears should be fine, but do the fronts say they are d30 or d44? Do they specify they are for a JK? Are their specific part numbers listed?

I know the front ones are for a D30 I'm just unsure of the whole "Short Reverse Pinion" part number is YUKYGD30SR-488JK

Looks like a Yukon D30 JK part number? You're good to go.
The front axles are high pinion, 'reverse rotation'. So gears that specify reverse are what you want.
These aren't for a JK, but they show the difference in the way the gears rotate.
