My JK has 37s and was just a weekend vehicle. Things have changed and now it's driven when it's not a Harley riding day.
I started with a Budget Boost of 1.75 spacers, sway bar drop bracket, and shock extensions (upgraded to Rubicon take off shocks). That's was with 305/70-16 Irok NDs... Now it's 37x14.00-17 Irok on beadlocks with flat fenders. I was running Tera Flex 4" (3" for Unlimiteds) springs and various Rock Krawler and other manufacturer's parts.
When you go over 3" there are other little things that can pop up that aren't addressed with the lift kit... If it's a DD and doesn't see much off-road add what it does is mild, save your money and reduce your headaches later on by doing 2.5" lift and 35s.
