Dutton-Lainson StrongArm® Electric Winch – 120V AC / 12V DC

The StrongArm® Electric Winch is built for demanding trailer and dock applications where a reliable, powered winch is essential. Its precision-engineered gear train delivers smooth, quiet operation session after session, while heavy-duty construction ensures it holds up in harsh marine environments.

Choose between a 120V AC model for dock or garage use where shore power is available, or a 12V DC model for on-the-road trailer use powered by your tow vehicle or a dedicated battery.

Key Features

  • Heat-treated sintered-iron gear train for smooth, quiet operation
  • Heat-treated high-carbon steel final drive gears for maximum strength
  • Precision needle bearings in high-load areas for low friction and long service life
  • Heavy-gauge, one-piece die-formed steel base for rigid, secure mounting
  • Brushed stainless steel front plate for superior corrosion resistance
  • High-impact housing for excellent weather and UV resistance
  • Cable hook with safety snap to keep your load securely attached
  • Emergency crank handle included for manual operation if needed
  • 12V model includes wiring harness, 25 ft. positive battery wire, and 8 ft. ground wire

Compatible Applications

  • Boat trailers
  • Utility and equipment trailers
  • Dock and garage winching (120V AC model)
  • Horizontal load retrieval applications

Parts Desk Insights

The StrongArm® is the right call when you need a step up from a basic strap winch — particularly for heavier boats or frequent launch-and-retrieve cycles where manual cranking becomes impractical. The 120V AC version is best suited for a fixed dock or garage setup where you have shore power and want push-button convenience. The 12V DC version is the go-to for trailering, wiring directly to your tow vehicle or a dedicated trailer battery. The included emergency crank handle is a valuable backup for power failures at the ramp. For best results, pair with a quality bow stop and a properly rated trailer roller or bunk system to reduce load on the winch during retrieval.
