Hi I’m planning on getting this part for my jeep jk 2012 sport. I’m also looking to install Eaton truetrac front and back will this fit that setup? Also what Eaton truetrac part will I need for rear and front? Thanks
Yes, this ring and pinion set could be used with Detroit Truetrac applications with the following links. Truetrac Dana 30 Truetrac Dana 44 . Thanks for your inquiry.
Hi! Would these fit a front Dana 30 with 30spl and a rear Dana 44 with 35spl?
The ring and pinion would be compatible but the carrier and axle bearings would be incorrect for the upgraded spline count. Thanks for your inquiry.
Will this fit my 1998 Grand Cherokee 5.9 Limited with a Dana 30 front and Dana 44HD axels? If it does not, do you have kits available for my 5.9?
No. Unfortunately, Yukon Gear does not offer this style of package for the ZJ Grand Cherokee applications. Sorry for the inconvenience.
I have a 2017 jku, to install this kit a new carrier is needed for the front axle (dana 30). I saw these carriers, both made by yukon, YCD706008 and YCD2010999. Which is correct and does anything else need to be purchase for the installation?
If you have a standard open differential and are reusing your factory spider gears, part number YCD2010999 should be used. Other parts should not need to be purchased for installation if retaining your gears. Thanks for your inquiry.
what are the ring gear bolt size for the front and rear?
Rear install kit includes both the OEM 1/2" bolts as well as the 7/16" bolts for use with other brands of carriers such as eaton/arb etc that do not drill proper size holes in the re carriers. The front includes both the OEM 7/16 bolts as well as 3/8 to fit aftermarket cases. Ring and pinions both front and rear are double drilled to accept both. Thanks for your inquiry.
Does this kit include pinion bearings?
Yes, it does. Thanks for your inquiry.
Does this kit include inner axle seals?
The front master kit does include new inner axle seals. Thank you for the question.
I have 3:21 gears and want to change to 4:11. Do I need to purchase anything else other than this kit?
Yes. Being that you have lower that 3.73 gears, you will need to change the case to a model that can handle carrier deck height found in 3.73 and numerically higher higher ratios. Thanks for your inquiry.
I have a 2018 JKU 4 door with Next Gen Dana 30 front and Dana 44 rear with 3:21 gears. I am running 34" measured tires and was looking to regear up to 4:56, can this be done by replacing the stock gears with the 4:56 from Yukon's kits or do I need to buy additional parts to complete this?
Jeeps currently with 3.21 gear ratio will require a new front carrier. Mopar front diff for 3.73 and higher numberical gear ratio Dana 30 Thanks for your inquiry.
Hi, since I have a 3.21 gear ratio and will need a new diff cover. Will I need a new spider gear set as well? Or can I use the factory one? If a new spider set is required can you please provide a link to the correct one needed? Thank you.
3.21 Gear ratio will need to change the front case for the spider gears so they can handle that carrier deck height difference. A case only would allow you to have your spider gears reused, but that is more labor intensive. Getting a pre loaded front diff case with spiders for the higher ratio may be a better way to go from labor cost standpoint. Here is the Mopar complete front locker for higher ratios.Dana 30 Front Case and gears for 3.73 and Numerically Higher Thanks for your inquiry.
