There are multiple different types of synthetic winch lines available today, many of them are made from Dyneema fibers, while others are made from, Technora®, Vectran®, Spectra®, or Kevlar®. Each fiber has benefits and disadvantages and can be chosen depending on your unique application.
Technora® and Vectran® fibers are very heat resistant but are susceptible to bend fatigue. This is not ideal for off-road winching since winch lines are repeatedly bent around radiuses, such as a fairleads or snatch blocks.
Spectra is similar to Dyneema fiber, but is not as strong or as durable. Because of its strength and durability, Dyneema is the premier synthetic fiber for winching applications. There are multiple different types of Dyneema fiber, with the two most popular being Sk75 and Sk60, Sk75 being the stronger of the two.
Regardless of the fiber, all winch lines are braided in a 12 strand construction. Each strand is composed of many fibers and 12 strands are woven together to form the rope.
All Master Pull winch lines are made with Dyneema Sk75 fiber ropes for superior strength and quality. We offer three different versions of winch lines of varying performance.
