Enhance your HO scale passenger cars with this pair of Kadee/AHM/Rivarossi 6-wheel passenger truck bolsters (Part # 380-505). These conversion bolsters allow you to equip passenger cars with truck-mounted couplers. Truck-mounted couplers enable closer coupling on 18' radii without binding for most passenger cars. For use with Kadee® Magne-Matic® Couplers, non-magnetic trucks are recommended. Wheels on AHM and Athearn trucks should be replaced with Kadee® #521 or #522 non-magnetic wheels. Each kit includes a pair of draft gear boxes, a pair of NO.5® Couplers, #634 centering springs, screws, special bolsters, and instructions.

Using this product is straightforward. First, if you're using AHM or Athearn trucks, change the wheels to Kadee #521 or #522 non - magnetic wheels. Then, use the included special bolsters to attach the truck - mounted couplers to your passenger cars. Make sure to use non - magnetic trucks when using Kadee Magne - Matic Couplers. When installing, follow the instructions provided in the kit carefully. For maintenance, keep the parts clean and free of dust. Periodically check the screws and centering springs to ensure they're in good condition. If you notice any parts are worn out, replace them promptly to keep your passenger cars running smoothly.
