I am curious to see which synthetic winch lines are the best quality. Are they pretty much all the same? Let me know what you think. |

No,
They are not the same. There are two suitable products for winching use (both have low energy if they break):
1. Amsteel Blue: least expensive, heat sensitive (not the best choice if you intend to do a lot of serious, heavy duty winching. It is good for most users)
2. Technora Line: expensive, low heat sensitivity, excellent for heavy duty use.
You can fabricate these lines less expensively than purchasing through traditional retailers. A good boat supply outlet or offshore company has the materials available.
The only issues that really change the price are the hook quality and the splice quality. A good splice should cost no more than $5 and an excellent latching swivel hook should cost no more than $35. A kevlar/nylon sleeve that slides over the hook and onto the line for abrasion protection can be purchased for about $4 for a 3 foot length. This material is used to protect ship tie down ropes.
My suggestion would be to fabricate an 85 to 100 foot, 3/8" Technora line and make an extension length out of Amsteel Blue at whatever length you think you need. This combo is very versatile and keeps the amsteel out of the "heat zone" on the winch. |

Please correct me if I'm wrong here, but all the info I can find shows 3/8" 12-strand Technora with a 10,000# tensile strength vs. 3/8" Masterpull with a 23,500# tensile.
"IF" that is correct - then it doesn't sound like a good choice.......

curquieta,
Where could one get the raw materials and where can you get the splices done??? |

i have never used one of these ropes but all I can say is 10k is no where near strong enough for a 5500lb truck no matter what the winch is capable of pulling |

Bill, where did you find those values? On the site I was looking at: http://www.4x4wire.com/reviews/oro_xline02/, they list the 5/16" rope as having a 14,000lbs break rating. Obviously the 3/8" would be higher.
I like the idea of having an aramid fiber because of the much better heat properties than UHMWPE. |

RE: Tensile Strengths
Amsteel-Blue:
3/8"---3.71 lbs. per 100ft
Average Strength 20,445lbs.
Technora:
3/8'---4.3 lbs. per 100ft
Average Strength 18,000lbs.
As I said, these are less costly substitutes.
Splicing can be done by any boat shop or sail maker and most off shore/boat shops stock or have access to these specialty ropes. |

The Am-Steel web site and Master-Pull both DO NOT recommend Am-Steel for off road winches...I'm using 11mm STA-Set T-900...rated for 15k, on a Warn 8k...no problems, extend with the same...I spliced the ends myself and haven't broke a splice, or a line yet with a lot use...Always double the pull, keep it centered and use common sense...
Cheers

Correct,
The manufactureres recommend against the use of these lines for winch use.
WHY?
Am-Steel is sensitive to heat. Winches produce a lot of heat. You can protect the line by putting heat protection on the line. Of course, you use at your own risk but Amsteel is being used successfully all over the place.
Dynex75 is probably the best solution and the most expensive. this product is made by a dutch company and they are just opening a plant to fabricate here in the US. It is not easy to get in short lengths which means you have to buy in bulk.
I believe the "new" masterpull ropes are made of this fiber. If you can afford the extra cost--this is definitely the way to go.
I am just suggesting alternatives.
Back to the splicing question, any big boat supply should have a splice kit available. |

Sorry if the values I posted were wrong, but I grabbed them off a couple different industrial rope/cable suppliers websites - they all gave approx the same tensile for the 12 strand Technora @ 10,000#
Not trying to start an argument here - just wondered - where did youn find the tensile info?
Doesn't really matter since I have a worm drive winch, but just curious all the same.
Thanks,

I posted this already but it failed.
I have the older MP UHMWPE rated at 11700 lbs for 5/16". I splice it myself. I believe it's quite ragged now and has suffered what seems to be UV damage. But seems to be holding up so far. I'm just not sure when to replece it. Have to call MP and get their opinion.
I believe the new MP and X-line are better as fars a UV, heat and abrasion resistance goes. So I'd get one of those. Having a very positive experience with Emil at MP, I'd give him a try. I'm also not sure if the new MP and X-line are one and the same. Both, I think, have higher stretch factor than the UHMWPE. |

No Problem,
My data came from the the American Group, Marine and Industrial Ropes.

Mongo, you have the Warn 8000 on your ARB DII huh? great. I was looking into buying that winch because of the price etc. Have you been happy with it and do you see a reason for me to purchase the 9000 instead? All of your input would be great. On another note...How are you doing? Didn't see you up at the recent rover event in Killington, VT? |

Hey Christian,
I proboably get slammed for this, but, the 8k beens great. No problems, but I always double the pull. I would have got a 9k, but it was a little to expensive...I have about 90' of rope on it, and I extend and use the rope for the pulley system. I'm actually using a CMI 25k rope rescue pulleys for the pulley system. It takes a little longer to rig, but I've never had a problem getting myself or any other truck out...lots of deep whale shit type mud, up and over rock piles, stuff like that. As for the Killington thing, I took a 7600 mile cross coutry trip (B2B,long story)...Syracuse to San Diego,Mexican Boder to Cananda, then back across Canada...great trip...
Cheers
