David “Diesel Dave” Kiley (born June 17, 1984) is an American diesel mechanic, entrepreneur, and reality-TV personality best known as the bearded half of Discovery Channel’s Diesel Brothers, where he and partner David “Heavy D” Sparks turned their Utah shop, DieselSellerz, into a playground for over-the-top custom truck builds and truck-giveaway stunts. Away from the cameras he trades wrenches for a steering wheel, piloting the 1,500-hp BroDozer and later BroCamino on the Monster Jam circuit—including the 2020 “Monster Jam: Breaking World Records” special—cementing his status as a crowd-pleasing showman on both asphalt and dirt.
