If your travels take you far off the beaten path, you need to be able to depend on your gear to perform. When it comes to winching, the Superline® Winch Line will not let you down. Made with heat-set Dyneema® SK75 synthetic rope, it is the strongest synthetic winch line on the market.

The Superline® is made with 12-strand Dyneema® SK75 rope that goes through a heat-setting process which stretches it into a denser, smaller diameter. This process nets large strength gains over normal Dyneema® SK75 rope. Not only does this increase safety, but it allows you to install a smaller diameter line on your winch without compromising strength. Using a smaller diameter will take up less space on the drum and the winch will work more efficiently. In some cases you can even install a longer line on your winch.

The Superline® also has excellent abrasion resistance and is coated with polyurethane for UV and chemical resistance. Combine that with only the highest quality hardware and high heat resistant Vectran drum protection, and you have a winch line that is worthy of the toughest vehicle extractions.

Will This Fit My Winch?

The 5/16" Superline® Winch Line works best with winches ranging from 8,000 - 10,000 lbs. For more information on what length/diameter to choose please reference our Winch Line Guide.

Eye Options

Soft Eye + Winch Puck

  • Compatible with most winch line shackle mounts when Winch Puck is removed
  • Winch Puck includes a safety strap to keep hands safe and clear from pinch points

Gusset Tube Thimble

  • Heavy duty tube thimble with welded gusset will not deform under load
  • Powdercoated black
  • Compatible with most hooks and winch line shackle mounts
  • Can be used with soft or steel shackles
  • NOTE: Not compatible with most wire rope clevis hooks

Tube Thimble + Sling Hook

  • Heavy duty tube thimble
  • Industrial Grade 100 Sling Hook
  • Heavy duty safety latch will not bend or break
  • Large opening (throat) easily fits rigging
  • Quickest and easiest rigging connection

Over Other Synthetic Winch Lines

  • Only synthetic winch line using Black Dyneema® fiber
  • Highest strength synthetic winch line available - 75% stronger on average
  • Use smaller diameter line without sacrificing strength - either gain winch efficiency or gain winch line length
  • Less stretch than normal SK75 winch lines

Over Steel Wire Rope

  • Safer than steel wire rope
  • Stronger than steel wire rope
  • Extremely lightweight makes it easy to use
  • Floats in water
  • Torque-free
  • No more cut hands from wire splinters or burrs
  • Will not kink like steel wire rope
  • Will not rust

Size Comparison

The high strength of the Superline® winch line allows you to install a smaller diameter line without sacrificing strength and take up less room on the winch drum. This has two main advantages:

  1. Your winch will work more efficiently. The further the winch line is from the center of the drum, the less pulling power the winch will have. Using a smaller diameter means that each layer of line is closer to the surface of the drum than a larger diameter line would be.
  2. In many winching scenarios it can be difficult to ensure the line is spooled on the winch neatly and the line can get bunched up on one area of the drum. This can allow the winch line to contact the winch housing or winch mounting plate, which can cause damage to the line or the winch itself.

Hover over the graphic below and you can see how much less room a 5/16” Superline® takes on a winch drum compared to our 3/8" Classic winch line. Note that the 5/16” Superline® is even 4,000 lbs stronger!


Despite all the benefits that the Superline® Winch Line has over steel wire rope, the proper precautions must be taken when using synthetic rope for winching. Synthetic winch lines are more prone to abrasion than wire rope, so ensure that the winch rope is rigged properly and isn’t rubbing on rocks, trees or other abrasive surfaces while under tension. This is why we include our removable Rock Guard to protect the rope when you can’t avoid contact with abrasive surfaces. Proper use and care is essential to ensure longevity of synthetic rope.

  1. Synthetic winch rope .

    Posted by Unknown on 19th Dec 2019

    First of all thank you master pull. Great people to work with great communication. I have not installed my winch rope yet still in a box but I got exactly what I asked for. And will be ordering other stuff too.

  2. Best Winch Cable

    Posted by Unknown on 11th Dec 2017

    I am impressed with the 5/16 Superline. It is very well made and is smaller in diameter and rated higher than my OEM Warn winch cable.
