In a Dark left-right gauge model, the neutral component of right-handedlepton doublet is odd under generalized R-parity and thus the lightest oneserves as the dark matter (DM) candidate. The coannihilation of the dark matterwith the singly charged Higgs triplet produces the correct relic abundance. Weexplain AMS-02 positron excess by the annihilation of 800 GeV dark matter into$\mu^+\mu^-\gamma$, through a t-channel exchange of the additional chargedtriplet Higgs boson. The DM is leptophilic which is useful for explaining thenon-observation of any antiproton excess which would generically be expectedfrom DM annihilation. The large cross-section needed to explain AMS-02 alsorequires an astrophysical boost. In addition, we show that the muon $(g-2)$receives required contribution from singly and doubly charged triplet Higgs inthe loops.
