i notice that ARB has 2 lockers for the JK rear 44 w/ 30 spline, one is 3.92 & up and the other is 3.73 & down. I currently have the stock 3.73 gears and i just want to add the locker to the rear for now, later upgrading the front axle and gearing lower. If I purchase the 3.73 & lower locker now would I be able to fit it with a lower gear or would i have to purchase the other locker (3.92 & up) to fit the lower gear?

Hello The standard JK Dana 44 rear non Rubicon will use only the RD117. All of the rear gears for the JK are designed to go on the 373 and down carrier / lockers. The only other would unit would be the RD147 if you wanted to upgrade to 35 spline axles. Thanks

Hello The labor rates vary from state to state. The best bet would be to call the local store and get the local price. Their number is 901-377-0323 Thanks
