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

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

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.

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.

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

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

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.

Update 2/28/23 The warrantee is not worth anything anymore it seems. Bought this set in March of 2019 and had them professionally installed. Front failed and had to be replaced in July of 2020. I just had to purchase the rear as it failed a couple days ago. I don't do anything hard core, and this is the extent of their longevity? Update 7/7/20 Ring gear in the front lost some teeth after a year and a half...Not cool Bolts didn't work. "Master rebuild" is deceptive. It doesn't have the axle bearings and seals. Garage quoted me $550 to do this rebuild. It ended up costing $1150 due to parts not fitting properly but it's done now. It costs more, but go with one of the complete kits preferably with the carrier housing and innards. Make sure you are getting the right series. My 2008 Wrangler rear D44 is series 3. You'll need to find out what yours is.

After lifting and installing bigger rims and tires my Jeep was sluggish and didn't get to speed quickly . After this swap it is much easier to get through all gears and get up to speed even on the highway.
