Product details

The Kadee 508 conversion kit fits suitable AHM/Rivarossi four-wheel passenger-car trucks. Its longer bolster arrangement positions the supplied No. 5 coupler for compatible truck-mounted passenger-car conversions.

Features and package contents

  • One pair of conversion bolsters.
  • Includes one pair of No. 5 couplers, draft gearboxes, No. 634 centering springs, screws and instructions.
  • Longer bolster configuration; not the short No. 505 arrangement.

Compatibility and installation

Assembly and fitting are required. Confirm the exact truck and car against the conversion instructions; wheel count alone does not determine fit. The 72-foot Con-Cor exception uses No. 505, and some six-wheel trucks have had their center axles removed. Use suitable nonmagnetic trucks and wheels; Kadee specifies No. 521 or 522 replacement wheels where appropriate. Check clearance, coupler height and operation through your curves. Cars, complete trucks and wheelsets are not included.

Small hobby parts; intended for modelers ages 14 and older. Manufacturer warning: cancer and reproductive harm.

Specifications are listed alongside the product details above.

Condition & collecting

Match the listed scale and track gauge to your layout. For locomotives, check the power system, decoder and sound details; DCC ready does not mean a decoder is installed. For rolling stock, check couplers, clearance and the manufacturer's minimum-radius requirement where provided.

Shipping & returns

Shipping, taxes and any applicable discounts are calculated at checkout.

Why these products?

We match the recorded product type, hobby, scale, maker and casting where those details are available. Explicitly selected items come first. Custom builds, loose cars, DIY kits and parts stay in their own lanes. Matching scale or brand alone does not prove compatibility.

Prices and availability are confirmed at checkout.
