The synthetic winch line official thread

[leiniesred]

I've done 5 back-to-back powered out downhill winches on my M8000 on my 4runner. The rope was undamaged.

Sure it was an iced trail in winter snow so the ambient temps were pretty low. Sure the brake on my winch has never really worked either, but no one else melted a winchline powering out 5 back to back sets. I think 2 of the Jeeps had rope, and the other 2 had cable. All had Warn winches with brakes inside the drum.

Shopping for replacement rollers to use in the fairlead my first thought was Viking. These are Delrin and $86.

But I came across a set made by Daystar, $40 and polyurethane.

So is there an advantage to Delrin over PUR for this application?

Delrin is stronger - it is a name-brand nylon variant. PU performance depends on a lot of factors, such as durometer - it comes in a wide variety of durometers. Softer is kinder to rope but will wear and gouge easily.

PU is generally more chemically resistant than Delrin, although both are susceptible to degradation from aromatic hydrocarbons and UV.

The higher cost of the Delrin rollers is probably because it was machined instead of extruded, Delrin material is generally less expensive than PU. The tooling for extruding PU is much cheaper than that for PU, so the Delrin rollers were probably machined.

At the end of the day, either would probably be superior to AL simply for corrosion resistance.
