Bondtech LGX Lite PRO Upgrade Kit for Elegoo Neptune 4

Enhanced Extrusion Control

The LGX Lite Pro Upgrade Kit replaces the stock Neptune 4 extruder with Bondtech’s high-performance LGX Lite Pro, known for its dual-drive technology and compact design. This results in stronger filament grip, better retraction behavior, and minimized risk of under- or over-extrusion during high-speed prints.

Material Flexibility

Thanks to its improved feeding mechanics, the upgrade supports a wide range of materials, including flexible and abrasive filaments. Whether you’re printing PLA, PETG, TPU, Nylon, or composites, the extruder offers consistent flow and better layer bonding.

Thermal Management and Print Quality

Combined with an improved heatsink and optimized mounting, the upgrade ensures superior thermal dissipation—critical during long prints or high-temperature operations. You get smoother surfaces, sharper details, and fewer clogs or jams.

Easy Installation

The kit includes all necessary mounting plates, spacers, and interface parts to ensure a clean and straightforward installation on the Neptune 4. No firmware changes are required, and Bondtech provides full documentation for setup and calibration.
