A lever-style free spool provides the option of hand or foot operation, and a rubberized 12-foot handheld remote is grippy and easy to use.

It is available with either steel or synthetic rope to offer you great all-weather performance. Installation is easy, simply mount four bolts to your trailer or flatbed.

S Series Winch Details

Superwinch S Series Trailer Winches are rated to pull up to 7,500 lbs. – yep, they’re strong. They use a 3.6 HP sealed permanent magnet motor driven through an all-steel 3-stage planetary gearbox. The machined aluminum free-spool lever can be operated by hand or with your foot. An innovative 2-hole drum prevents the rope from detaching from the drum, which uses an automatic, load-holding brake and includes stainless steel rollers and fasteners to reduce corrosion. A yellow-tinted protective cover offers additional safety while protecting the rope and drum. Weighing 42 lbs for the synthetic rope and 51 pounds for the wire rope, the S Series mounts easily using just four bolts.
