M939 parts — Vehicular Power Transmission Components

M939 series 5-ton 6x6 trucks. The M939 series is the 5-ton 6x6 truck family of the 1980s and 90s — M923 and M925 cargo trucks, M929 and M930 dumps, M931 and M932 tractors, M934 vans and the M936 wrecker.

SECO holds 17 NSN-identified M939 parts in FSC 2520, Vehicular Power Transmission Components, on our own shelf in Augusta, GA — counted, condition-coded and quoted the same business day; 13 are photographed and priced for card checkout.

A part is listed here when its federal item name, SECO's description or its store listing names the M939 or one of its models (M939, M923, M924, M925, M926, M927, M928, M929…). Not every part that fits says so — if yours isn't here, search the full catalog by NSN or part number.
