Four years later, Triarsi made a one-off return to racing by competing in the Sebring round of GT World Challenge America for his Ferrari-fielding Triarsi Competizione. Racing in the Am class alongside Charlie Scardina, Triarsi scored a class win in race one. Returning to the series for 2022, Triarsi won ten of the 12 races he contested in the Am class en route to the title, which he sealed with two rounds to go. During 2022, Triarsi also raced at the season-ending Indianapolis 8 Hours in Pro-Am, as well as making a one-off appearance in the GT America Series at Nashville, in which he won race one. The following year, Triarsi primarily raced in the endurance rounds of the IMSA SportsCar Championship in GTD for his own team, taking a best result of fourth at the Six Hours of The Glen. During 2023, Triarsi made a one-off return to Ferrari Challenge North America at Road America, winning race two, as well as racing with his own team at the Indianapolis 8 Hours, in which he was involved in a collision with Augusto Farfus with two and a half hours left to run.

In 2024, Triarsi solely raced in the endurance rounds of the IMSA SportsCar Championship, in which he took a best result of fourth at the 24 Hours of Daytona and Petit Le Mans. The following year, Triarsi originally had planned to contest the endurance rounds, but later added three more races to his schedule to accommodate Kenton Koch. In his first near full-season in IMSA, Triarsi took his maiden series win at Road America, and a pair of second-place finishes at VIR and Petit Le Mans en route to an eighth-place points finish. Triarsi then returned for the endurance rounds of the IMSA SportsCar Championship in 2026.
