Unfortunately, you cannot add the factory trailer brake if you do not have the JL1 package. The rear module and wiring harness is not there, and cannot be added unless you want to spend some serious cash. So if your truck did not already come with the brake controller and has the JL1 package, it will not work, and you have to go aftermarket brake controller.
Thanks for the info. Just went ahead and ordered the RC 2" for the front. Hopefully I'll get to them tonight, if not definetly this weekend. Then it will be time for tire and rims.
Does anyone have the torque specs on doing just the front end lift? I am looking at the RC 2" front life only, just need to find the torque specs on all the bolts that need to be retightened when all said and done. Thanks
