I have a 2020 JL Sport S 2 Door and am just starting to get into modifying it for trail use after 4,000 miles. I'm trying to do a build on a budget because I'm military and quite frankly don't earn a lot of money to put towards this. My goal is to buy most things used if possible and use a lot of factory parts, specifically from Rubicon's. My current goal is somewhat 3 parts. Get used JLU Rubicon suspension, get used Rubicon tires (eventually getting 35's and new fenders). I know that if I can get a JLU Rubicon suspension from one that had a hard top+steel bumper I should be able to get at least 2" of lift. But I've read on forums that some people need to extend certain parts of the undercarriage in order for everything to run smooth. Also with the drivetrain, should I have any concerns with it regarding a lift? I don't ever plan on lifting above 2.5". This is my only vehicle so I'm trying to make it trail-capable while still able to drive well on the road. If anyone can provide any information regarding my questions, or point me to forum threads, I'd really apreciate it!
