Improved Extrusion Control
The LGX Lite Pro Upgrade Kit replaces the standard extruder of the Neptune 4 with the powerful LGX Lite Pro from Bondtech, known for its dual-drive technology and compact design. This ensures better filament grip, improved retraction properties, and minimizes the risk of over- or under-extrusion at high speeds.

Material Versatility
Thanks to the enhanced feeding mechanism, the upgrade supports a wide range of materials, including flexible and abrasive filaments. Whether it's PLA, PETG, TPU, Nylon, or composites – the extruder delivers consistent flow and better layer adhesion.

Thermal Management and Print Quality
With an improved heat sink and optimized mounting, the upgrade ensures effective heat dissipation – crucial for long print times or high temperatures. The result: smoother surfaces, sharper details, and fewer clogs.

Easy Installation
The kit includes all necessary mounting plates, spacers, and interface components for easy installation on the Neptune 4. Firmware changes are not required, and Bondtech provides comprehensive guides for setup and calibration.
