Renfrow started his CTS career in 1996, running seven races. His debut came for the #41 George Turnage Dodge team at Bristol. He started the race in 15th position, but finished 27th after mechanical issues. In fact, Renfrow would only finish one race in 1996, a race at Richmond in which he would finish 12th. It would prove to be his only top-20 finish on the year. However, Renfrow qualified well. He had two top-10 starts, the best being a 5th at Nashville.
