What is a good thickness of synthetic line for the 12k winch? Is 3/8" enough or do I need to get the 1/2"? I'm looking at this to replace the stock cable.

The diameter depends on the grade of the line you are using. We (Southeast Overland) uses Samson's Amsteel Blue, which is a Dyneema SK75 fiber and a 3/8" line has an average break strength of 19,600 lbs post splice.
Your link has 1/2" line with a "12,500 lb capacity." I'm assuming capacity = break but that is left up to interpretation.
You need your line to have at least 1.5 times more strength than your winch and I prefer closer a 2:1 safety factor ratio if possible. I would not run a 12,500 lb line on a 12k winch. Go minimum the 3/8" 19,600 lbs we sell and we have even sold a good bit of 7/16" line @ 23,900 lbs average break.
I've repaired several broken "budget" lines and have not been impressed with their construction and wear characteristics. I have the broken pieces in the shop to show as examples. One splice was so woefully inadequately buried I'm glad the user only pulled an ATV once before the hardware crumpled and it required use. A heavy pull could have been bad.
Feel free to call us @ 864-280-4238 or email Sales@SoutheastOverland.com and we are happy to walk you through your selection.
3/8" is rated for 17k I believe...or 17.5k...I'd check, but the Southeast Overland site is funky this morning... (stupid internets...obviously, just a fad...)
19,600 lbs baby!
I'm not sure whats up with our website. I just pulled it up OK but I know there have been issues the past couple of days. It looks like it is a HostGator problem but my IT dude is looking into it more.
That link shows a 1/2" line rated at 12.5k...IMO, don't buy it...stick with one of the quality winchline vendors...a GOOD 1/2" line will be rated more in the 22k range...
1/2" Amsteel Blue is rated at an average break for 34,000 lbs.
and your HF 12k only holds 80' anyways of 3/8"...IMO, 70-80' is plenty on the drum, and get a good 50' extension line to carry for longer distances.
Extensions are nice. You don't often need them, but when you do you reeeeeally do.
My winching situation would have been a disaster if the line had broke...a stalled winch would have meant an interesting recovery, a busted line would have equaled some major vehicle damage. I am as "cost effective" as the next guy, but winch line isn't one of them.
Yuppers. A winch line isn't somewhere you want to skimp and you can get a quality line for a reasonable price if you know where to look.

We stock diameters from 1/8" up to 1/2", specifically 1/8", 3/16", 1/4", 5/16", 3/8", 7/16" and 1/2". We also have the all important color selection of blue, orange, silver, and dark green (depending on the diameter).
