Real newb question here.

When you guys change your gears, what are you actually, physically swapping out? Do you replace the pinion gear and the ring gear too? I'm trying to understand these basic concepts. Thanks

 

Yes u buy the ring and pinion kit of the gear size of your choice. Make sure you buy and overhaul/install kit for it as well.

 

Are these ALL you need? Like if you buy a ring and pinion set with overhaul kit (superior axle brand) and install my jeep will be set with new gears? Sorry, I'm a bit new too.

 

Id also add inner axle seals to the list. The I ordered 5.13 Yukon gears with overhaul kits from Northridge, the overhaul kit was actually not from Yukon, I wanna say it was superior, and it did not have axle seals with it. I was in a crunch when I got mine done last week and didn't have time to wait for new seals to arrive. Shop left the old seals in and turns up the front left is leaking pretty good.

 

You could call Dave at Northridge4x4 and he will help you out. But to answer your question, yes. Buy your gears & master overhaul kit for the front and rear. The shop that does the install will most likely have the required different gear oil.

 

Got my Yukons from Northridge and the overhaul kit was Motive Gear.

 

Thank you gentlemen!

 

Motive Gear it is. I knew superior didn't sound right. The ring gear bolts were of a lower quality as well. Two broke threading them in, before any torque was even applied. I ended up using ARP bolts that a local parts store happened to have in stock.
