Ahm/Rivarossi 4-Wheel Passenger (KAD508)

HO AHM/Rivarossi 4-Wheel Passenger Car Conversion Coupler is a conversion kit that upgrades 4-wheel passenger cars to truck-mounted couplers using a conversion bolster, enabling closer, smoother coupling on tight curves.

Designed for AHM and Rivarossi passenger cars, the kit includes two draft gear boxes, two couplers, centering springs, screws, special bolsters and instructions. When paired with non-magnetic trucks and Kadee Magne-Matic couplers, it supports reliable operation on radii down to 18 inches. For best performance, replace the trucks’ wheels with non-magnetic wheelsets.
