Synthetic Winch Ropes


Synthetic Winch Rope is the latest technology for winches. Offering a substantially lighter option to cable, it is just as strong and removes the worry of splinters or kinking a cable! Retrofit to Sherpa winches as well as other brands.

  • Superior safety compared to steel winch cable.
  • Various lengths and load ratings available.
    • A great upgrade for steel cable winches. Rope is lightweight, floats on water, doesn't recoil and still offers the high breaking strength of cable.

    • The hook end has a stainless steel sleeving making hook attachment simple, yet strong and prevents abrasion on the rope.

    • Sherpa 4x4 can also supply aluminium hawse suitable for use with rope.

    • Manufactured to maintain braking load even after years of use. Fully UV, abrasion and chemically solvent resistant.

    This is high-quality winch rope as used on all our Sherpa winches. Don't risk the cheap junk on the market as the breaking strains are lower than advertised.

    Attaching to the Winch Drum

    Sherpa winch drums are designed so they can accept either type of rope end crimp (pin type or screw on type).

    Winch Rope Models: SWR28MB, SWR30MB, SWR45MB

    Standard synthetic winch ropes in 28m, 30m and 45m have the following crimp to attach to the winch drum.

    Winch Rope Models: SBTWR12, SDB10X28, SWR45MB

    The 12m (7mm) rope with hook, double braided rope with spectra and the Sherpa 45m ropes in 12mm have the follow screw on type connection.

    Double Braided 100% Spectra Rope

    Also available is a new 100% USA Spectra fibre winch rope with a double braided configuration. This rope feels amazing to handle and also looks great. The welded thimble end on these ropes is extra strong and will not crush under high strains.

    This rope has a protective outer jacket but manages to maintain a high breaking strain due to the quality USA Spectra fibre construction. The 10mm overall outer diameter makes it a great upgrade for most winches on the market.

    Grunter Boat Winch Synthetic Rope Alternative

    This is 12m of 7mm synthetic rope supplied as an alternative to the 50mm webbing on boat trailer winches. Supplied with the drilled lug on the drum end for easy fitment and a marine grade stainless steel hook on the other end. These hooks are stamped with a WLL of 1,000kg.

    Warning: Sherpa 4x4 still recommends the use of a winch dampener when performing a vehicle recovery with winch rope. Winch ropes should only be used on 'brake in gearbox' style winches. Brake in drum winches can get extremely hot causing damage to the rope which will reduce its MBS. If upgrading an old brake in drum winch to synthetic rope it is highly recommended you insulate your drum to limit heat transfer.

Comment on synthetic winch rope.

Too soon to tell, have not used it yet.

Dave Blythe
12mm over 10mm just feels better!

My standard Sherpa 17,000 Ilb winch came with a 10mm rope and I upgraded later to the 12mm - just because the 10mm looked so weedy pulling my 6tonne it feels proper good with 12mm. Easy to change too!

Chris Flemmich
Better than webbing strap

The Sherpa Grunter winch is awesome and makes retrieval of boat a breeze. I have a 6.5m fibreglass and the winch simply pulls the boat u over the rear trailer centre roller so easily. This also centres the boat on retrieval. Used with the rope option and remote, well I have to say it's so much easier and actually makes boat retrieval fun and not a headache.
Thanks Sherpa, your Grunter winch rocks.
