Kadee HO Gear Boxes are designed to provide secure and accurate coupler mounting for HO scale locomotives and rolling stock. Whether you are replacing worn components, upgrading factory-installed coupler boxes, or completing a custom model railroad project, Kadee® offers a wide selection of gear boxes, shims, sleeves, lids, and related hardware to ensure dependable coupler performance.
Kadee® manufactures gear boxes in various styles and sizes to accommodate different mounting requirements and model manufacturers. Along with gear boxes, you can choose from shims to adjust coupler height, sleeves for proper mounting alignment, and replacement lids that securely retain the coupler assembly. Selecting the correct combination of components helps eliminate binding, prevents unwanted uncoupling, and improves the overall reliability of your HO scale equipment.
During any installation, it is important to verify that the coupler moves freely inside the gear box and that the mounting screws are tightened correctly without restricting movement. Proper alignment and coupler height should also be checked using a Kadee® Coupler Height Gauge to ensure smooth operation with other rolling stock. These simple adjustments can greatly improve train performance and reduce maintenance over time.
This Kadee HO Gear Boxes guide explains the different gear box styles, available shims, sleeves, and lids, along with recommendations for choosing the right components for your model railroad. Whether you are repairing older equipment or building new HO scale rolling stock, Kadee HO Gear Boxes provide the quality, precision, and durability needed for reliable operation on any layout.
