Sway bar disconnects do allow for more suspension travel. You would NOT want to run a jeep with the sway bar disconnected in any situation other than 4x4ing. Always reconnect before getting back on the main road heading for the highway and home.
Good to know!
Next question, parabs mentioned that he was looking at an Unlimited Rubi due to the extra wheelbase giving you towing capacity, and more available gas tank upgrades. All of these sound like good reasons, however I haven't seen many Rubis (I'm only looking at the TJ models, can't afford a JK) available, let alone Unlimited editions.
Also....I've heard the 5-speed in the 2003-2004 models is more durable / seems stronger than the Mercedes 6-speed from the 2005+ years. Of course, to get the Rubicon Unlimited, you need to go with the 6-speed transmission. Is it worth the tradeoff?
Passengers will have a little more legroom, and there's a bit more cargo space, which sounds nice, but I don't plan on having more than one passenger a lot of the time, so it's not a big deal. I would also guess the added length = some additional weight = more fuel consumption and harder on the brakes.
I would assume most parts would be compatible (engine, windshield, most of the interior, front/rear bumpers, etc), however the tops, running boards / sliders, driveshafts, and some other parts would be different....do they tend to be harder to find for the unlimited editions? and I'm guessing probably cost a little more?
Plus there's the additional upfront cost, but, I'm generally a firm believer in doing it right the first time, even if it costs more, so if an unlimited would suit my usage better, then I'd rather buy it right now, than wanting to upgrade in a few years.
