8: Johnny Benson Jr.
Some drivers didn’t need a long career to establish dominance, and Benson Jr. is one of them. Benson Jr. is one of only three drivers who have managed to win a championship in two different racing categories, the Busch Series and the Craftsman Truck Series. He cut his career short in 2010 and faded into a quiet retirement ven though he still appears on NASCAR TV from time to time.

Benson works for the National Motorsports Appeals Panel, which deals with driver complaints. He is also still actively driving at the ISMA tour, operating a super-modified car that’s owned by Brad Lichty. There aren’t a lot of drivers who had the short but meaningful success Benson Jr. had.
