G2 Performance Ring & Pinion sets are engineered with todays most demanding applications in mind. Designed to hold up to oversized tires and high performance engines, these gears use use the latest technology and materials in their manufacturing to give you the strongest and quietest performance gear sets available.
For pulling a small trailer it is so much better than the 3.73 stock gears.
Everything buttoned up fine. The instructions were good on the alignment issues and marking, but lacking on the torque specs for the bolts. In particular the torque for the crush washer on the pinion. That was an issue that was not entirely resolved with internet searches. I don't believe my impact ever obtained a crush on that washer and since this was a crawl under install using cheater bars wasn't much help. There seemed to be considerable debate as to what the torque on that nut should have been. I went with as much as my impact wrench could do then backed off until I had what I felt was a safe load on those tapered bearings. No oil leaks, back up and running. It's very quiet and smooth. Very happy with the results but would have appreciated a little more help on the torque specs.
Installation was a breeze. I do recommend these for anyone regearing
I have a 2012 jeep 4 door,skyjacker 7" long arm,42.50x13.50x20" boggers,with procomp driveshafts,After having the dealer install the 5.13 gears,and getting a flash PAC for tuning,I can hold the brake and gas pedal let off the brake and spin the back tires on pavement.not for a long distance but that's how much power it gave me.the guys at the dealership thought I was crazy cause I only have stock axles, but I'm eventually getting g2 axles
Hi, i have a 2011 Wrangler 2 door Automatic, I'm going to be putting 35" tires with a 3" long arm lift. Will this what Ratio be good for mostly road use and decent trail ridding? What would you recommend?

I have a 2015 JKU with 3.21 gears, now would I have to buy anything else other then a diff cover and this kit and be set for the installation? Or would I need to purchase anything else if so can you guide me in the right direction with part numbers. Thanks

Chris, the G2 Axle and Gear JK Front and Rear 4.56 Ring and Pinion Kit will also require you to purchase a front carrier, which can be found here: http://www.4wd.com/Jeep-Drivetrain-Jeep-Axles-Differentials/Open-Differential-Case.aspx?t_c=12&t_s=237&t_pt=5589&t_pn=D%2fS2010999 Thanks for the question!

It says " Everything included for installation on your Jeep" Why does it say that if you have to buy another carrier for a stock front Dana 30? I almost bought this until I read that. Glad I didn't.

Hey Mikie2013, the G2 Axle and Gear JK Front and Rear 4.88 Ring and Pinion Kit would possibly need a new carrier depending on what ratio is in your Jeep now. If your now has a 3.55 or lower numerical ratio then you would need a new carrier. Thanks for your question.
