synthetic winch lines

Question: for those of you running synthetic winch lines, do you keep the winch rope off the winch until needed, then thread it in the winch? or do you keep it on full time?.

Keep it on full time. I assume you are worried about UV damage and road grime? If you are just get a cover for your winch.

I'm glad somebody posted this because I was thinking of posting my own "school me" thread. Since I am in the process of losing even more weight on the rig, I started thinking about this. Here's the questions, the Amsteel 3/8 line is rated to 17,600 which the web says is good for a 9,500LB winch. Then the masterpull super line in 5/16 says it is up to 16,500 and is rated for a 9,500 winch also. How can this be? With a 9,500 which I have, if you add a snatch block you can generate up to 19,000 LB. But I have never seen anyone sporting over a 3/8 and I see a lot of people running a 5/16, not masterpull. How can that work?

I was wondering about UV damage, water/dirt/grime exposure etc. Thinink of converting (still have a steel line).
Problem is, superwinch does not make a winch cover for the S9000 winch, I have search high and low. I used to rock climb, so I am aware that dynamic ropes in climbing need to be replaced if exposed too much, too old, or have suffered
too many dynamic fall shocks. With static ropes, ie: rapelling, the ropes usually last longer. But they are usually stored when not in use. So the question is how long will a winch rope last, exposed to the elements in the front of the vehicle?.

I second Buckon's question..

uv is not a problem we used this stuff [Dyneema] on sailboats for years without too much uv degradation. look at your wraps on the drum if your spooled out to double. How offen do you use your winch with one wrap??? Also consider the weight of the truck. If your worried use 3/8's
All this being said I do not have any on my winches cuz there under my work bench> when I do mount them I will get some used stuff from a sailboat for free & run till I can't splice it any longer.

Avoid chafe keep it clean your good to go

Oh ya when you 2:1 you reduce the poundage on the line by half [except at the snach block]

Actually, the poundage on the line stays the same, at the level of whatever the winch is pulling on it. The snatch block connection to it's anchor does indeed double. If you have a 9500lb winch pulling that, the line will be at 9500 lbs. The bumper will have 19000lbs and the snatchblock will have 19000 lbs. I know that is what Peter meant, and I was just clarifying it.

IMHO, use 5/16" on 6000 lb winches and lower only. Use 3/8" on winches to 9500 pound. Use 7/16" to 12000 lb.

Synthetic or wire, same suggestion. Winch manufacturers should be put in jail for selling 9500 lb winches with 5/16" line.

With the synthetic, you really should put it on under some tension. If you don't, it pulls down into the lower layers under load and really mashes the rope into shapes that it shouldn't see.

Interesting guys. Thanks. It looks like the 5/16 masterpull superline would be cool then at 16,500LB. My truck weighs less than 4,000 LB's, I think.

Good info, thanks, going to a rope line seems like the way to go. Always worried about getting cut in half by the steel lines when I winch...

Bill as some good things to say about Amsteel Blue
http://www.bb4wa.com/articles/amsteel2.htm


This is the best place I have found to buy it
http://www.rockstomper.com/index.html

The Masterpull and Warn Lines are a waste of money IMHO

I have had synthetic on my winch for 6 years and aside from ruining the thimble on the end, have had 0 issues. It has been in constant exposure to the elements. It has no apparent degredation. I have the 5/16 and chose that because it put more line on the drum.
The line was purchased from Rockstomper and is the gray looking stuff in some of the pictures on their website. Back then it came with a heat wrap to protect the rope that came into contact with the hot drum. Guess I should add one of their friction guards for the other end since its only $10.

Anyone running delrin rollers on their original fairleads, or did you switch to the hawse type?

I've had my 3/8 rope for 6-7 years now too and the one thing I did notice recently is that it holds moisture against the drum. I took the rope off and sanded and rust prepped my drum to prevent further damage.

FWIW- it has held up surprisingly well to the elements and abuse all things considered.

Go 3/8". 5/16" is way too easy to break.

I have the masterpull 3/8's thick superline thats rated at 26,500lbs, It's really strong but when I bought it for my old winch i could only run 85' feet of it so I had to buy an extension. But I love synthetic rope and would never go back to steel cable again, I would go with masterpull if you do go with synthetic

guys it does not really matter who's line you buy. As long as you get Am Blue & not just blue Dyneema.
The difference is only the loop splice which any of you guys can do in 5 min. The MOST important part of the splice is the taper of the tail if it is not smooth it will fail there.
