What are the power ports like?

I work a lot in the dark. Does it have some kind of lighting system I can use or hook up?

The SuperWinch S102734 has LED task lighting that you can use when things get dark around you and your winch.

I’m what you call an extreme user. I need to know my electronics are gonna work when I put them in… Tougher situations, what can you tell me about that?

The electronics are fully potted so they should be able to absorb a lock more shock and vibration than other electronics. It should also keep it moderately safe from moisture and other elements that could be corrosive.

Does it have a manual clutch or automatic?

While we are on the topic of the remote… Can you tell me if it is wired or not? Is it possible to have it wireless?

The standard stock option is a wired remote that will vibrate. However, you can upgrade to a wireless remote if you so desire.

I see they call this an Expedition grade winch. That means almost nothing to me. Can you tell me why this winch is so special?

The line speed is faster than other winches. The winch scores in the mid-40’s which, of course, is directly affected by capacity.

What else is great? I’m not completely sold on a faster line speed.

The electronics are fully potted like we said. We all know that not all winches are like this and if you are stuck in the mud, it is raining, or any other myriad of situations where debris or liquid could get in your winch then you will appreciate how important this is for your peace of mind.

Any other reasons I should be completely sold on a SuperWinch?

Yes. SuperWinches are easier on your rope. The last thing you want is for your rope to snap and SuperWinches do their best to make sure they do not by using reinforced drums, brakes in optimal positions, and a large radius Fatlip Hawse.

Ok, cool. Could you tell me about the rated pull line of this winch?

Sure, the winch has a rated line pull of 12,000 lbs or 3630 kgs.
