E-40 and Sacramento Kings Squash Beef, He Drops 'Front Row 40' Single

E-40's been hot about Sacramento Kings' security booting him from Game 1 of their playoff clash against the Golden State Warriors ... but tensions have since subsided, and their beef's officially been squashed.

On Thursday, 40 dropped his new single, "Front Row 40" ... which features the legendary rap star spitting his patented slang from inside the Chase Center where his beloved Warriors play.

Sources close to the production of the Jae Synth-directed video tell TMZ Hip Hop that 40 actually filmed the visual several months ago, and had always planned to drop it parallel to the Warriors' postseason run.

The clip also leverages plenty of star power ... with cameos from JAY-Z, Diddy, Snoop Dogg, Too $hort, 2 Chainz and GSW stars Steph Curry and Draymond Green.

But, the rollout takes on new meaning now in the wake of his removal from Sacramento's Golden 1 Center last Sunday, which resulted in 40 deeming the org racist -- but both sides are putting it in the rearview.

40 and the Kings released a joint statement that spoke to the issue's conclusion ... “Contrary to speculation, Mr. Earl 'E-40' Stevens did not stand excessively from his ticketed courtside seat; the outcome resulted from an unfortunate misunderstanding between both parties.”
