Shanna Moakler -- Selling Off $2.6 Million Pain In The Calabasas

All it took was 7 years and a few alleged death threats, but Shanna Moakler is finally ready to say adios to the house she's shared with Travis Barker ... even AFTER they got divorced.

Sources say Moakler is looking to put distance between herself and Travis so she's selling the 5 bedroom, 6 bath crib in the ritzy Oaks neighborhood of Calabasas. Asking price -- $2.6 million.

The couple divorced in 2008, but continued living together part-time in the Calabasas for the sake of raising their kids. We're guessing cohabitating just became too much when they were both arrested back in December for allegedly exchanging violent threats.

We're told construction's almost complete on Shanna's new home in nearby Porter Ranch -- and Travis already has his own place in L.A.
