The 1380 shock cord ring is a heavy-duty aviation landing gear elastic component used in light aircraft and utility aircraft landing gear systems. It is constructed from high-strength natural rubber strands with a durable braided protective cover, forming a continuous loop designed to absorb and dampen high landing impact loads.

This type of shock cord is part of the MIL-C-5651B family and is used where higher load capacity is required compared to standard light aircraft shock rings. It helps reduce structural stress on the airframe by absorbing energy during touchdown and taxi operations.
