In this paper, we introduce the concept of gr-Le-Jgr-PSub in the context of graded commutative rings and graded modules. These submodules extend and unify the properties of gr-Le-PSub and gr-J_gr-PSub through a fixed gr-Id L=⊕g∈Ω Lg. The research develops foundational definitions, proves equivalences, and examines the structural implications of these submodules under various module-theoretic operations, including localization, direct products, and quotient modules. Examples are provided to illustrate the distinct nature of graded Le-Jgr-prime submodules compared to other graded submodules. Furthermore, conditions under which these submodules exhibit maximal and semisimple properties are characterized, contributing new insights to the theory of graded modules.
