Questions About: Gear Ratios, HD Alternator, Towing Package
Iím hoping some of you more knowledgeable than me can help me here. We purchased a pre-owned 2006 SMB and Iím trying to learn as much as I can about it. Along with the vehicle, we received the original vehicle description (window sticker). On the vehicle description it lists several items under the Optional Equipment section I would like to learn more about. Here are the items I need help understanding.
1. 3.73 Ratio Limited Slip Axle: I think this is a good thing when traveling in areas where traction might be a problem. While not as good as a locker, it seems better than the stock axle for limited off-road use. I would like to know what the 3.73 Ratio means. Is this a higher or lower gear ratio than the standard axle gear ratio?
2. HD Trlr Tow Class II/III/Iv: What components are upgraded on the vehicle besides installing a trailer hitch when the vehicle was manufactured? Are other components such as engine and transmission cooling capacities increased? How about brakes etc.?
3. HD Alternator/HD Battery: Whatís the difference between the standard alternator and battery and an HD alternator and battery?
4. Auxiliary Fuel Port: What the heck is an auxiliary fuel port? I havenít a clue about what this might be but think it might be a good thing to know about should it ever come up along the way.
This forum is great and I look forward to any help any of you might be able to provide on these things.
