Stromberg Carlson12V Electric5th Wheel Landing GearStromberg Carlson LG-5 Electric Landing Gear -- Push-Button Leveling for 5th Wheel Trailers

Stop cranking by hand every time you set up camp. The Stromberg Carlson LG-5 replaces manual landing gear legs on most 5th wheel trailers with a 12V DC electric drive system, letting you raise and lower your front end from a rocker switch. At 46 inches long and built from heavy-duty steel, this is a direct-fit replacement designed for the standard leg pockets found on a wide range of 5th wheel frames -- no custom fabrication required for most applications.

Ditch the Hand Crank -- Go Electric on Your 5th Wheel

Landing gear is one of the most-used mechanisms on any 5th wheel, and manual cranking gets old fast, especially after a long travel day or when you're solo camping. The Stromberg Carlson LG-5 electric landing gear system is engineered as a bolt-in upgrade or replacement for standard 5th wheel landing legs, converting your setup routine to simple switch operation powered by your rig's 12V DC system.

The LG-5 ships as a complete gear assembly at 37 lbs., spanning 46 inches in length -- sized to match the typical spread found on mid-size to full-size 5th wheel trailers. The 11-inch width and 8-inch height profile keep it within the standard frame channel dimensions used by most North American 5th wheel manufacturers.

12V DC Electric Drive

Runs off your trailer's existing 12V battery or converter. No generator, no inverter, no extra power source needed at the campsite.

Drop-In Replacement Fit

Designed to replace standard factory landing gear legs on most 5th wheel trailers. Mounts into existing leg pockets on the trailer frame.

Heavy-Duty Steel Construction

Built from steel with a corrosion-resistant finish to handle road grime, weather exposure, and the repeated load cycles of full-time or frequent use.

Full Assembly Included

Comes as a complete landing gear unit ready to install -- motor, gearbox, and leg assembly in one package at 37 lbs. shipping weight.

Why Upgrade to Electric Landing Gear?

Manual landing gear on a heavy 5th wheel can require hundreds of crank turns and significant physical effort, particularly when the trailer is heavily loaded. Electric landing gear eliminates that entirely. The LG-5's motor and gearbox do the work while you monitor the height from outside the truck. For full-timers, older campers, or anyone who unhitches and hitches frequently, the difference is immediately noticeable.

The LG-5 is also a practical replacement for manual gear that has worn out, stripped gears, or a bent leg from road debris -- situations where a full leg replacement is already necessary. Installing electric at that point costs only marginally more than a manual replacement and adds permanent convenience.

Solo Camping Advantage: Electric landing gear is particularly valuable when you're unhitching alone. No need to crawl under the trailer to crank while also monitoring truck position -- operate the legs from one spot with the rocker switch.

Installation Overview

The LG-5 mounts into the standard square leg pockets welded to the underside of most 5th wheel trailer frames. Typical installation involves:

  • Removing the existing manual landing gear legs from their mounting pockets
  • Sliding the LG-5 assembly into the same pockets and securing with the existing cross-bolts or U-bolts
  • Running 12-gauge or heavier wire from the trailer's 12V battery or converter to the motor leads
  • Installing the rocker switch in a convenient interior or exterior location (switch sold separately unless noted)
Wiring Note: Plan for a dedicated 20-amp circuit to the landing gear motor for reliable operation under load. Use appropriately rated wire for the run length from battery to motor location at the front of the trailer frame.

Compatible Trailer Types

The LG-5 is designed for standard residential-style 5th wheel trailers common from manufacturers including Forest River, Keystone, Heartland, Grand Design, Coachmen, Jayco, and others that use conventional square-tube leg pocket frames. Verify your existing leg pocket dimensions against the 46 x 11 x 8 inch profile before ordering if your trailer uses a non-standard frame configuration.

Measure First: While the LG-5 fits a broad range of 5th wheel frames, some ultra-lightweight trailers or specialty frames use narrower leg pockets. Confirm your trailer's existing leg pocket width and depth match the LG-5 footprint before installation.
Maintenance Tips: Grease the screw drive mechanism at the start and end of each camping season. Inspect motor wiring connections annually for corrosion, especially at the battery terminal. Keep the leg inner tube clean of road grit to prevent premature wear on the drive screw.
Pair With: Add a Stromberg Carlson landing gear pad or foot plate under each leg tip to prevent sinking into soft ground at the campsite -- especially important when the trailer is fully loaded.

Important Information
  • Always verify that your trailer's leg pocket dimensions are compatible with the LG-5 (46 x 11 x 8 inch profile) before purchasing -- non-standard frames may require modification.
  • Never operate landing gear with the trailer still fully coupled to the tow vehicle under load -- unhitch per your trailer manufacturer's procedure before extending legs.
  • Use a minimum 12-gauge wire run (heavier for longer runs) and a dedicated 20-amp fused circuit for the motor to prevent voltage drop that can cause sluggish or failed operation.
  • Do not use landing gear as the sole support when working under the trailer -- use rated jack stands rated for your trailer's loaded weight.
  • Inspect the mounting pocket welds on your trailer frame before installation -- electric gear places cyclic load on these points and any cracked welds should be repaired first.
  • This product ships at 37 lbs. and 46 inches long -- plan for curbside delivery or store pickup accordingly.
