MB Motorsports was an American professional stock car racing team that competed in the NASCAR Camping World Truck Series.

In 1997, the team made a total of three races, with the first one coming at I-70 Speedway with Rick Beebe qualifying ninth but finishing 24th.

Doug George began the 1998 season with MB, but a failure to finish higher than 30th and three consecutive DNQs forced him out of the ride.

The team switched to a part-time schedule for the rest of the season, with Randy MacDonald, Beebe, and Bryan Reffner driving.

Jamie McMurray ran five races for the team, and had a best finish of eleventh at Las Vegas Motor Speedway.

McMurray was selected to make a full-time run for Rookie of the Year in 2000, but left midway through the season for TKO Motorsports.

During the O'Reilly 400K at Texas Motor Speedway on October 13, Roper crashed heavily on lap 33, and suffered a neck injury that would prove fatal the next day.

Rookie Larry Gunselman joined the team, bringing sponsorship from Waterloo Tool Storage, and occasionally running Chevrolets.

Mike Harmon also drove one race at Dover International Speedway, but finished thirty-fifth after an early ignition failure.

In 2004, rookie driver Chris Wimmer drove ten races with Porter Truck Sales sponsorshing, and had a best finish of eighteenth.

For the rest of the season, Scott Lynch and Jack Smith shared the ride with Cooper Bussman sponsoring.

For 2010, young driver Nick Hoffman made his Truck Series debut at IRP finishing 23rd.

Smith's return to MB brought sponsorship from Seal Wrap, as well as consulting from Paul Andrews.

Jennings ran a large portion of the schedule, but Stenzel and Blake Koch also drove Mittler trucks during the season.

Justin Jennings and Tyler Tanner ran the majority of the schedule for the team, which fielded two entries; a full-race 63 and a start-and-park 36.
