Stromberg Carlson12V ElectricFifth Wheel Landing GearStromberg Carlson LG-6 Electric Landing Gear -- Ditch the Hand Crank for Good

If you're still cranking your fifth wheel jacks by hand, the LG-6 electric landing gear system from Stromberg Carlson ends that. This 12-volt dual-motor kit replaces your existing manual front jacks with a fully electric extend-and-retract system, operable from a wired hand control. Designed specifically for fifth wheel trailers, the LG-6 fits into standard drop-pin receiver tubes already present on most fifth wheel frames, making installation a bolt-on project for anyone comfortable with basic wiring and hand tools.

Stop Cranking. Start Camping.

Manual landing gear is one of the most complained-about tasks in the RV lifestyle -- it's slow, it's hard on your back, and it can be downright dangerous on unlevel ground. The Stromberg Carlson LG-6 swaps that chore for a push-button experience. Both legs extend and retract simultaneously under motor power, leveling your trailer faster and with far less physical effort.

The LG-6 ships as a complete kit at 42 lbs and measures 46 inches long x 11 inches wide x 8 inches tall in the box, sized to accommodate the full leg assembly and hardware needed for a standard fifth wheel installation. Stromberg Carlson is a well-established name in fifth wheel accessories, and the LG-6 is their core electric landing gear offering -- purpose-built for the fifth wheel segment rather than adapted from a generic trailer jack.

12V Dual-Motor Drive

Independent motors power each leg simultaneously for fast, even extension and retraction without manual synchronization.

Drop-Pin Frame Mount

Fits standard drop-pin receiver tubes found on most fifth wheel trailer front frames -- no custom fabrication required for compatible trailers.

Wired Hand Control

Corded control pendant lets you operate extend and retract functions from a safe, comfortable position during hookup and unhooking.

Full Replacement Kit

Ships as a complete assembly including legs, motors, mounting hardware, and control wiring -- everything needed to replace worn-out or manual jacks.

Who the LG-6 Is Built For

The LG-6 is aimed squarely at fifth wheel trailer owners whose rigs either shipped with manual jacks from the factory or whose original electric jacks have worn out. Full-timers who hook and unhook frequently get the most immediate benefit -- the time savings add up fast when you're moving every few days. Weekend warriors benefit equally on arrival after a long drive when fatigue makes hand-cranking even more of a chore.

This is also a popular upgrade for older fifth wheel trailers built before factory electric landing gear became common. If your trailer frame has standard drop-pin jack receiver tubes -- which is the norm across most Forest River, Keystone, Grand Design, Heartland, and similar fifth wheel frames -- the LG-6 is designed to drop in without custom bracket fabrication.

Drop-Pin Compatibility: The LG-6 uses the industry-standard drop-pin mounting interface. Before ordering, confirm your fifth wheel frame has existing drop-pin receiver tubes at the front. Most fifth wheel trailers built in the last 20 years use this mounting standard. Trailers with welded-on manual jack mounts may require additional bracket work.

Installation Overview

Installation of the LG-6 involves four main steps: removing your existing manual jacks from the drop-pin receivers, inserting and pinning the new electric jack legs, routing the 12V power leads to your trailer's battery or breakaway circuit (typically using 10-gauge wire for the run length involved), and mounting the control pendant in a convenient location near the front of the trailer. Most owners with basic mechanical and electrical skills complete the job in two to four hours.

  • Connect to your trailer's 12V battery system -- the same battery that powers your breakaway switch and other trailer accessories
  • Use appropriately sized wire for the run to minimize voltage drop, which reduces motor torque and speed
  • Route wiring away from moving parts and heat sources; secure with loom or conduit where exposed
  • Test full extension and retraction before relying on the system for trailer support
Wiring Note: Landing gear motors draw significant amperage during operation -- especially at the start of extension when load is highest. Use a dedicated circuit with an appropriately rated fuse or circuit breaker. Undersized wiring is the most common cause of slow or intermittent electric landing gear performance.

Replacing Worn or Failed Electric Jacks

The LG-6 is a natural replacement for factory-installed electric landing gear that has reached end of life. Electric jack motors fail over time from moisture intrusion, corrosion at connectors, and simple wear on the motor brushes and gearbox. If your existing jacks are slow, noisy, or completely unresponsive, the LG-6 provides a fresh-start solution rather than chasing individual motor or gearbox repairs.

Maintenance Tips: After installation, apply a light coat of white lithium grease to the jack screws periodically to extend gear life. Keep the motor housings clear of road debris and rinse off road salt after winter travel. Inspect the drop pins and cotter pins each season for wear or bending.
Weight Capacity: Always verify the rated lift capacity of the LG-6 matches or exceeds the front pin weight of your specific fifth wheel trailer. Exceeding rated capacity can damage the motors, gearbox, or jack legs and may result in trailer instability. Check your trailer's pin weight specification on the weight sticker inside the front storage compartment.
Common Application: The Stromberg Carlson LG-6 is frequently used on Forest River Montana, Keystone Cougar, Grand Design Reflection, Heartland Bighorn, and similar mainstream fifth wheel trailers with standard drop-pin front frames. If you're unsure about fitment for your specific trailer, check the front frame rail for existing drop-pin receiver tubes -- two rectangular tubes, one on each side, with through-holes for the mounting pins.

Important Information -- Read Before Installing
  • Confirm your fifth wheel trailer frame has standard drop-pin receiver tubes before purchase -- welded or non-standard jack mounts are NOT compatible without additional fabrication.
  • Always chock trailer wheels and verify the fifth wheel hitch is disconnected from the tow vehicle before operating landing gear during installation or daily use.
  • Never use landing gear as the sole support when working under the trailer -- use rated jack stands.
  • Verify the LG-6 lift capacity meets or exceeds your trailer's actual front pin weight before relying on it for support.
  • Undersized or excessively long 12V wiring runs cause voltage drop that reduces motor performance and can lead to premature motor failure -- use appropriately gauged wire for your installation.
  • Do not operate electric landing gear if legs are obstructed, on extremely soft ground without pads, or if unusual noises or resistance are present.
  • This product is intended for fifth wheel trailers only. Do not attempt to use on bumper-pull travel trailers, gooseneck trailers, or motorhomes.
