Replace a worn or damaged front jack on your fifth-wheel's Lippert Ground Control 3.0 leveling system with the Lippert Ground Control 3.0 Hall Effect Front Jack (Part 305340) — a 5,000 lb-capacity electric leveling jack that works as either the left OR right front leg. Available at The RV Surplus.

⭐ Fits Either Side — Left or Right Front

This jack is configurable as either the left or right front leg on a Ground Control 3.0 system — one SKU covers both corners. Includes the motor, footpad, and mounting brackets for a complete leg replacement.

⭐ What "Hall Effect" Means

Ground Control 3.0 jacks use Hall Effect sensors instead of mechanical limit switches. The sensor reads the motor shaft's rotation magnetically, which lets the controller:

Know exactly where the leg is in its stroke at all times
Coordinate all legs together for true auto-level
Detect stalls, over-current, and loss of position

Hall Effect jacks and older limit-switch jacks are not interchangeable. If your system runs Ground Control 3.0, order this part; older Ground Control (non-3.0) systems take different legs.

⚠️ Replace in Matched Pairs When Possible

Jacks on the same corner pair wear at similar rates. If one front jack has failed after years of service, consider replacing both fronts together — the "fresh" leg can over-work against a tired one and lead to premature failure.

⚠️ Before Calling It a Jack Failure

Jacks that won't run aren't always the leg's fault. Check:

Battery voltage at the controller — Ground Control systems need real current; a weak battery presents as a bad jack
Controller fault codes — the GC 3.0 controller indicates which leg has lost communication or stalled
Wiring and connectors — corrosion at the motor plug is common on front jacks exposed to road spray
Manual override — turn the drive shaft with the override wrench to confirm the jack body is free before condemning the motor
