When I bought my rig it had the long arm lift and 37s... The guy didn't wheel it, and It had held up fine for him.. Mine is a 2005 with the 6 speed manual. It had the dana 35/30 and had the warn full floater rear kit.. It had 456 gears and seemed to move along just fine.. The moment I got into some moderate four wheeling on my first trip to the local mountains, it blew the rear end... I fixed it and took it out again... Blew the rear end again.... Then I Went one ton..
It seemed to handle the tires while in two wheel drive, and the previous owner never had any problems, but as soon as you really put it to the test, it would snap... Literally
My ride- 2001 power wheel, 11" plastic tires, upgraded battery, boat sides, custom bumpers, tow hooks, new paint.
