What's your brand recommendation?You may not be concerned with safety, but think about others that could be around you...I’m sure they would like to be safe! Synthetic is the way to go...if it breaks, you can also splice it in a pinch. Weight is helpful...don’t cheap out on a winch, it’s one thing you will want to work and work well when you need it.
Hummmm so I'm finally looking to purchase a winch and I think I've narrowed down to the x20 smitty. This is solely due to me being a cheap a$$... Steel vs synthetic? I'm not concerned with safety per say.. proper winching procedure should negate injury...(here's hoping and praying)
Weight savings is my thought. 32 lbs saved... Is that worth 220 bucks?

I can't think of a reason NOT to go synthetic...
David_Bricker said:UV degradation. See it in the desert. But, that's easily solved with a cover.
Uv along with being impregnated with mud around here were my thoughts.... Normally if I'm stuck I'm in a muddy situation.
As to the rated strength I have concerns... Since synthetic is safer when it brakes, it makes me wonder if it has a lower factor of safety than steel line.... Just thinking out loud.

Lol yes all of this is in my thought process. Engineering school ruined me.... What I was meaning in my previous post was most cables are rated at half of actual load capacity ( when lifting) .... I wonder if synthetic is rated at maybe .75 capacity due to danger being much less dangerous due to less stretch.A fair point, and a cover is a good idea.
The term "Factor of Safety" generally describes how many multiples of the "rated" load something is materially capable of handling (for example, a bridge rated 10 tons is likely built to handle 25-30 tons, because it has to be able to handle that 10 tons over the entire course of its life in service (which for highway bridges, could be decades, while the whole time the materials it's made from are aging from UV, vibration (vehicles/pedestrians crossing it), temperature cycles, and chemicals (winter deicer, acid rain, etc.).
In this case, let's say your Jeep weighs 4500lbs (a nice, round number). 3/8 steel is rated 14,400lbs breaking, so the factor of safety for steel is 3.2 in this case - the line can support 3.2 of your Jeep as a single load before breaking. 3/8 Synthetic rated for 17,600lbs gives a factor of safety of 3.911, so it can handle almost 4 of your Jeep, so the 3/8 synthetic has a higher "factor of safety" in this scenario.
As to your thinking on breaking behavior, stretch a rubber band until it snaps - stings when it whips back at where you're holding it and whacks you, doesn't it? This is what steel line is capable of when stretched to breaking. Synthetic is more like cotton sewing thread - pull on it until it breaks, and it pretty much just falls down.
Steel has a significant "plastic deformation" range - within that range you can deform/stress (stretch, in this case) it and when the load is removed it'll spring back like that rubber band. Exceed that range, and you break the line (snapping the rubber band). Steel is a very strong material and it has a sizeable plastic deformation range (it's what makes it such a strong/resilient structural material); exceed it and the material fails. When it does, the failure (snap) only relieves the stretch/tension at the exact point of failure - the rest of the line is still intact and has all that stretch energy in it, and it has to go somewhere. That's why when a steel line snaps it's like that rubber band - when the material parts at the failure point, the two now-loose ends recoil with devastating force. That force, multiplied by the mass of the cable (and steel cables are HEAVY), adds up to a LOT of momentum and it will do damage.
The Synthetics, on the other hand, have a higher failure strength but (assuming here) a very narrow "plastic deformation" band, so they can't really store up any energy, just like that cotton sewing thread (which, if you try the exercise I described above, shows little to no stretch before snapping). That's why the ends of a snapped synthetic line don't go hurtling back at you - there's no significant stretch to release once the line lets go, and the only significant force acting on it at that point is gravity. Besides, with a MUCH lower mass, even if the snythetic does recoil slightly, it'll do a LOT less damage.
(apologies for the long reply - I got started, unconsiously tapped memories of my materials engineering class in college, and got on a roll)
It's to help have equal ish flex front and rear. My front goes to full flex before my rear really starts doing much. And that seems to be somewhat normal for an xj. So slightly control the front to force the rear to act right.Maybe I'm not understanding your thought process, but most people remove or disconnect their sway bar to help off road with more articulation.
I looked at their website and it looks like maybe Antirock is an articulating sway bar? I don't quite get their set up.
