Product Summary

These replacement arms are designed to be used with the CURT hitch-mounted bike rack #18,021, allowing it to be transformed from a 2-bike model to a 4-bike model as needed. The arms easily and securely bolt into place and feature rubber cradles that hold the bike frame firmly in place during travel, without scratching the finish.
