Honda String Trimmer Brush Cutter Gearbox for UMK431 / UMK431K1 Models

We offer a brand new genuine Honda brush cutter and string trimmer gear box for all Honda UMK431 and UMK431K1 (all "types" for both models) models. Please be aware that this gear box is ready for a string trimmer head, but requires use of your existing bottom cup, spacer, and blade mounting nut if you are using a brush cutter blade.

The Honda part number for this assembly is 41100-VL1-023, which replaces part numbers 41100-VL1-013 and 41100-VK4-M01, and it comes fully assembled and ready to bolt on. 

If you are not COMPLETELY certain as to the exact model of your trimmer, please contact us with your complete serial number before making your purchase. We will be happy to verify what you need. Replace your worn-out gear box and be back in business!

This is a special order item that typically ships in about 5 business days.
