I am looking at starting to slowly upgrade my 2008 jk unlimited. I'm wondering where to begin? I would like to see some improved highway performance, and I would like to take it out on the dunes at Silver Lake State Park. Nothing crazy, just some small hills and running on the flats. Any suggestions?

 

tires and maybe a leveling kit

 

I would start with a superchips flashpaq, especially if your jeep is automatic. It makes a world of a difference with the 3.8l.

 

I would to lift, tires, and regear.
