Weight Question

So I have a weight question. In the next couple of months, I will have the money saved ups to buy and get the lift kit, tire and rims installed on my JKU. I will be getting a AEV 2.5 DualSport XT Kit. So, I have the potential of getting a new front bumper my Smittybilt . Now if I get the bumper, do I need to add heavier springs to my front end to prevent sagging? Or is there something else that needs to be added?

Install your lift, and take a measurement. Install all the extra stuff and then take another one. More than likely, you'll only see about a 1/2" loss in lift... maybe 3/4" at most. Once you determine this, install coil spacers of the loss measured and call it a day.
