Yukon Gear & AxleGear & Install Kit for Jeep JK non-Rubicon 4.88 Ratio - includes ring and pinion (4.88 ratio) - YGK013

I upgraded my differential gears due to bigger tires on my Jeep. I like how these gears give my Jeep a little pep. They live up to the Yukon name.

Came in fast , packed well, just what I needed !

Las instale las corona y piñón el 2022 asta hoy en día diciembre 2024 están en perfectas condiciones busca un mejor mecánico que sepa hacer el trabajo y que sabe lo que hace porque si instala un mecánico que no sabe créeme que cundo entras en el monte se te va romper el piñón si no haces off road en unos 4 meses o menos se romperán y dirás que la marca yukon no es de buena calidad ..en mi experiencia lo que antes de romper las coronas y piñón son las puntas de eje bueno si vas hacer (Offroad) espero que lo entienden y que le sirve de ayuda

4.88 Yukon gears blew apart at only 3 months after installation. Had a licensed mechanic do the install, this is a daily driver and minimal off roading mainly on logging and forest services roads. No lockers and not beat on. axel shafts, drive shafts, carrier and housing are all OEM. Not happy with the poor quality of what is supposed to be top of the line performance parts in the off road community.

So far the only things that I can say about the product is that it was packaged very well and shipping time was reasonable. The whole gear set is still sitting on the workbench along with the other parts that I have acquired. I’m still in the process of acquiring parts for the project.I will submit an update sometime in the future.

35" tyres. 3.73 ratio. My Wrangler was one hell of a slouch and such a pain to drive. With the 4.88 Yukon set the absolute joy of this vehicle has returned. You will definitely not regret this upgrade in any way at all. This engine loves the higher revs at 5th gear and delivers better fuel efficiency against the airflow on that flat windscreen.My installer loved this set and there is zero noise of any kind between this and stock.

Lots of offroad parks, out of state wheeling trips, 1 year of locker use.. forgot to turn off locker once offroad and once turning onto paved road. Ox locker required modifications to pinion for clearance reasons, which i found out after pinion contacted lock ring... 1 year later pinion failed... Can't say I'm that upset. Pinion lost teeth ring gear

Had the parts in 1 day. Awesome.
