Funny you should bring that up. I have come to the conclusion that any bigger than 35's leads me down a road where there is much less original jeepness to it. Also, at 37's, why not 40's. Then why not full hydro and some big 8 lug tons and on and on until it's just a cut up frame and tub. I really do like the feel of the LJ after driving it so much over the last 4 years and it has earned the right to remain intact after 180k in new york with the previous owner and just 20k with me. I come back to this forum because the builds here adhere to the original form while improving them for more serious wheeling duty.If you ever think you'll go bigger than 35s, you may want to consider a different front axle. That's not to hate on the HP44, they just use the OEM size ball joints. Otherwise it sounds like you're thinking through everything! It'll be fun to watch your build if you do a thread.
I had the same philosophy with my JK. It was really good for a stock vehicle, but after 2 years in its current form, this is how the rubicon should have come from the factory for the price. Locked 44's with a 3 or so lift on 35's. Took some time to gather the parts but it was a bolt on party and was a fun project. I want this LJ to fulfill my desire for a more purpose built rig with some more alteration but nothing diverging from it's jeep feel.
Thanks again for the thoughtful insight and informed opinions.
