Q: I already have the rock jock 60 rear ... Is there a problem with the front 60 being wider than the rear or are the factory axles the same Answer this question

A: Hello Jim, No issues at all. In fact the front axle is always wider on a solid axle vehicle. This helps the car steer correctly. If the rear was wider the car would drive like a tricycle. I hope that helps. Thank you.

Q: I have a 2013 JKU and have. 3.5" lift already and I have one of these on order already and realized I'm not sure if the factory front drive shaft will work with it or do I need to buy an after market one to fit? Answer this question

A: Hello The Rock Jock axles use a standard style u-joint in the 1350 series. Yes the front shaft has to be replaced with a u-joint type shaft. We have a number of companies that offer the shafts or it can be built at a local shop. Thanks

Q: Will factory wheels mount on this axle. Answer this question

A: Hello Jeff, No, the 2007 to 2014 Jeep JK Wrangler factory lug pattern is 5x5. This G2 axle upgrades you to the larger 5 on 5 1/2 bolt pattern. Thank you for the email.
