View partLippert Ground Control 3.0 Fifth-Wheel Leveling Jacks: Parts Diagram & Numbers
Use this reference to identify the major components of Lippert Ground Control 3.0 electric automatic leveling systems fitted to fifth-wheel RVs. It separates front landing gear, rear Hall Effect jacks, optional mid-jacks, the motor, controller and remote. The four-point and six-point versions do not have identical hardware or controllers. Ground Control TT is a different system for travel trailers.
Manufacturer diagrams and safety manuals
Lippert's official Ground Control documentation contains illustrated four- and six-point layouts, the landing gear and Hall Effect jack illustrations, wiring and controller revision references. Compare your jack tag and control panel before using the parts below.

Ground Control 3.0 jack identification and photograph
Lippert's current Ground Control LCD Components CCD-0002690 uses factory callouts A–I for the front jack, left/right rear jacks, optional short rear jacks, drive motor and hardware. Other pages identify remotes, harnesses and four- versus six-point controls. Match the maker illustrations to your original jack label and the product photographs below.

Where the major parts are fitted
Left and right square landing gear. Replacement front Hall Effect jack 305340; compare serial number and existing motor.
Two mid-jacks on selected six-point systems stabilize after leveling. Their operation differs from the front and rear legs, and they must not be ordered by location alone.
Standard left 305339, right 344792. A shorter left-leg configuration uses 342610; never mix sizes without confirming your installed setup.
An electronic module connects the motors, sensors and touchpad. The 803280 control is specifically listed for the 358590 four-point version; confirm revision.

Front and rear leveling jacks — exact manufacturer numbers
These are complete replacement assemblies rather than separate mechanical service screws. Front and rear jacks differ; left versus right and short versus standard rear jacks must be matched to the installed system.
Lippert identifies this as a front landing gear replacement usable on either left or right front side. Not a rear jack.

Left-side rear Ground Control replacement with 12.5-inch stroke; 24.5-inch retracted, 36.75-inch extended per Lippert. Match mounting and leg dimensions.
View part
Right-side companion to standard left leg 305339. Not the shorter rear configuration. Confirm installed jack stroke and side.
View part
Short left rear jack for applicable six-point Ground Control 3.0 layouts; 12.5-inch lift, 21.5-inch retracted and 34.75-inch extended nominal height.

Manufacturer-identified Hall Effect jack motor; inspect the existing jack, harness and original motor number before servicing.
View part
Lippert identifies replacement module for 358590 four-point system; supersedes 304136 and 694656. Do not assume it replaces a six-point controller.
View part
Remote for compatible Ground Control 3.0 systems; match existing remote/controller generation. Charging cable is not included.
View part
Replacement charger only for the matching Ground Control remote. This is not the leveling touchpad or jack controller.
View partFour-point versus six-point identification
Two front electric landing gear plus two rear Hall Effect jacks; compare controller label and LCD/OneControl system revision. 803280 is a manufacturer-listed replacement module for 358590, not a generic controller for all four- and six-point systems.
Two front, two rear and two additional mid-point jacks. Lippert's complete replacement/upgrade kit 675817 is a six-point configuration. Mid-jack part numbers and controller revisions must be confirmed against the individual system.
The 672136 five-point travel-trailer leveling kit, 421483 TT controller and 421484 TT touchpad do not belong in this fifth-wheel parts breakdown. Do not select an item based on the shared Ground Control name.
Check before purchasing
- System: identify Ground Control 3.0 fifth-wheel versus travel-trailer TT, and whether the installed system has four or six jacks.
- Jack label: compare the original Lippert part number, whether front/rear/mid, left/right, stroke and original mounting brackets.
- Control: use the part number on the existing module, touchpad style and revision. A compatible-looking connector is not evidence of compatibility.
- Manual: follow the current Lippert procedure for re-homing/recalibrating the system after a qualified repair.
Safety: Ground Control 3.0 jacks must not be used as service stands or to raise a wheel for tire work. Follow Lippert's safety instructions; secure and independently support the trailer as required before any service.
