In 2008, Sellers signed on with Andy Santerre Motorsports in the No. 44 Chevrolet. Sellers took the pole and the win at the season opener at Greenville-Pickens Speedway, in Greenville, SC. The victory was short lived due to a rules infraction. Sellers was stripped of his win and given a 30th-place finish. At Iowa, in the closing laps, Sellers took second from Austin Dillon before a caution but he was placed back into fourth place on the restart (the position he was in on the restart after the previous yellow) because the NASCAR officials determined that a full lap had not been run since Sellers was in fourth and he never had the chance to challenge Brian Ickler for the lead. In the season finale, at Stafford Sellers finally win his first race. He finished the season 8th overall points standings, with a series high 3 poles. Peyton again came close to taking the win at the Toyota All-Star Showdown, with Jig-A-Loo as his sponsor, when a last lap spin out, while in the lead, made him finish 14th.
