Drop in custom designed coupler boxes. Designed to specifically fit the Bachmann GP40*. One set includes boxes for front and rear of locomotive. These boxes are 3D printed using ASA black color filament for toughness and will stand up to the outdoors. They drop right in place, no modifications to the locomotive are needed (to prepare for installation, just remove the stock couplers and centering springs). They match up to Kadee G height gauge. These boxes accept Kadee 907 knuckles, springs, and screws (not included; buyer must supply their own). Please allow 3 days for processing as orders are often 3D printed upon ordering.
Installation Note: Visit our “How-To” page for installation instructions.
Please Note: As with all 3D printed parts, there may be slight differences in the finish between the photos shown and the product received. If you have any concerns at all, always please reach out directly to us!
