Authenticity & Accuracy
The 1952-1957 backbone support tube 1 inch is the period-correct replacement tube for the backbone support used in late 1952 through 1957 Big Twin frames. Manufactured to exact original dimensions and wall thickness, it ensures a precise fit for late Panhead frame restorations requiring period-correct tubing. Note that this tube differs in specification from the earlier 1937-1952 version and is not interchangeable.
⚠️
Always weld according to the specifications named in our frame certificate. Deviating from the specified procedures may affect structural integrity and will void the warranty.
