9553SF driveshaft is an unwelded 1310-series PTO driveshaft kit designed for cut‑to‑length installations in heavy‑duty drivetrains. The kit is built around a 2.00" diameter tube with a.083" wall, and it includes a slip yoke, a weld yoke, and a U‑joint kit, with the complete driveshaft designated as part number R9553‑SF. Typical lengths for this 1310‑series unwelded assembly run around 55.7 inches, with published examples showing 55.68" (Neapco N9553SF) or 55.75" (Meritor documentation) depending on configuration. Because the shaft is unwelded, it is intended to be cut to length and welded to the required end configurations to fit PTO‑driven power transfer applications in trucks and off‑highway equipment.
