[QUOTE="dieseljeep, post: 425137, member: 18592"] Once I re-gear, I think my TJ will be very nice on the highway for a Jeep. It's not bad, but many those 3.07s just aren't enough for mud tires, roof, rack, winch, etc. Before the rack you had to look down more often to make sure you hadn't drifted up to 80+mph. I wasn't even running a front sway bar then either, so it was incredibly sloppy with turns, but that torque will fool you. You don't speed up quickly with low hp/high torque, but you tend to slowly drift to higher speeds. I'm also waiting to put on my black magic brake stuff when I swap in the 3.73 axles with ARB lockers for the TJ. I think that's really gonna make that drive really well on the road after that. Off-road, has got to wait until I pick up an Atlas. It's way too fast off-road. At a minimum it needs to be half the speed it currently can do and I think 3.73 and 5:1 will make it good enough. If I can figure out how to get the AX-15 5.15 first gear, then that's gonna happen. The gearing looks great for a 5.15 AX-15. Should be able to take off in second without any throttle and the 5.15 will be very handy with a trailer or on gravel/rough roads. And a 96 crawl ratio gives me a bit of a smile. I think Grant will end up getting the Kubota to where it'll run the highway pretty well, but I'm not so sure it won't require a bit of black smoke at times. I think he'll likely end up with a slightly bigger turbo and enough fuel, which I would guess isn't injected as finely as common rail, and before the turbo spools up, I'm guessing he'll be a bit sooty.
