After Victory Road the Motor City Machine Guns entered a Best of Five Series with Beer Money, Inc., contested for the TNA World Tag Team Championship. Beer Money won the first two matches, a ladder match and a Street Fight, after knocking their opponents out with beer bottles. However, Shelley and Sabin came back to win the two following matches, a steel cage match and an Ultimate X match, to even the score to 2–2 and set up a deciding match for the August 12 Impact!. On the August 12 Impact! the Motor City Machine Guns defeated Beer Money, Inc. in a Two Out of Three Falls match to win the Best of Five Series and retain the TNA World Tag Team Championship. The following month at No Surrender, the Motor City Machine Guns retained their titles in a match against Generation Me. After the match Generation Me turned heel by attacking the Machine Guns and injuring Shelley in storyline. On the following Impact!, Generation Me laid claim to the TNA World Tag Team Championship, claiming that the champions would not be able to defend them for 30 days, due to Shelley's injury, before stealing Sabin's title belt. Shelley would however make his return two weeks later and promised Generation Me a rematch for the World Tag Team Championship at Bound for Glory. At the pay–per–view the Motor City Machine Guns defeated Generation Me to retain the TNA World Tag Team Championship. Also at Bound for Glory, Team 3D announced their retirement from professional wrestling, but requested one final match against the Motor City Machine Guns, whom they called the best tag team in wrestling. The Motor City Machine Guns accepted and the match took place on November 7, 2010, at Turning Point, where they defeated Team 3D to retain the TNA World Tag Team Championship. After Jeremy Buck pinned Sabin in an eight-person tag team match, where the Motor City Machine Guns teamed with Jay Lethal and Velvet Sky and Generation Me with Robbie E and Cookie, on the November 18 Impact!, the Motor City Machine Guns challenged Generation Me to an Empty Arena match. The match took place later that same night on Reaction with the Motor City Machine Guns coming out victorious. On December 5 at Final Resolution the Motor City Machine Guns defeated Generation Me in a Full Metal Mayhem match to retain the World Tag Team Championship. The following month at Genesis, Shelley and Sabin lost the World Tag Team Championship to Beer Money, Inc., after Roode rolled up Sabin, following a miscommunication between the Machine Guns. Shelley and Sabin received their rematch for the title on the following Impact!, but lost again due to a miscommunication. On January 16 Shelley broke his collarbone during a match in Hagerstown, Maryland. Originally, Shelley was advertised to make his return on April 17 at Lockdown in a nine-man Xscape match, but on April 7 he was removed from the match and his return postponed. Shelley made his return on April 20 at the tapings of the April 28 Impact!, saving Sabin from Mexican America (Anarquia and Hernandez). Ironically, the same day Shelley made his return, Sabin suffered a knee injury in his match with Anarquia. Later that same week, Sabin underwent knee surgery, which would sideline him for the rest of the year.
