Tricon Garage, formerly known as David Gilliland Racing, DGR-Crosley, and Team DGR, is an American professional stock car racing team that competes in the NASCAR Craftsman Truck Series. The team was founded in early 2017 when racing team owners David Gilliland and Bo LeMastus came together to form a collaborative effort from their respective teams, David Gilliland Racing and Crosley Sports Group, known as DGR-Crosley. DGR-Crosley fielded Toyotas in 2018 and 2019 before announcing its switch to Ford starting in 2020. The team reverted to the David Gilliland Racing name in 2021 as Johnny Gray became a co-owner. Former co-owner and driver Bo LeMastus remained with the team in a marketing and sponsorship capacity.
