[QUOTE="Dirty Dog, post: 459315, member: 24042"] You're starting from a good place. A stock JK Wrangler is already capable of running the Rubicon Trail. Doing so is part of the Jeep development cycle, so you're all set. A 3-3.5" lift and 35's will do you just fine. Avoid the error of too much wheel and not enough tire. You need tall sidewalls for off-highway use. Get a cheap inflator so you can air down. Lower tire pressures smooths out lumps and allows the tire to wrap around obstacles. That wrap means a larger contact patch. Which means better grip. Which means less stuck. Because winching isn't wheeling. That combo will rub a lot when flexed. At minimum, you will want to do a bit of trimming on your flares and the lip of the wheel well. If you can, replace the plastic junk with good high clearance metal flares. Quick Disconnects for your swaybar are a must. You're going to want lockers. When people say they're "on a budget", that often means things like ARB and Detroit are out of the question, so look at lunchbox lockers. They're very inexpensive. And since you're in there doing the lockers, re-gear. You've most likely got 3.73 gears (or worse... 3.21...) and you're going to want more. You can never have too much gear in the rocks. Like pretty much everything else on the market, the non-Rubicon Wrangler has a 2.73:1 low range. OK, but not stellar. The Gold Standard would be to swap in an Atlas 4 speed transfer case and pick anything up to a 10:1 crawl ratio as needed. But that's not budget friendly. I think the least expensive good option is a Rubicon transfer case. That 4:1 low range makes a big difference. [/QUOTE]
