About Us

Founded in 2005 by Chris Buhidar and Christopher Alaniz, Truck Source Diesel has quickly become San Antonio’s premier dealer for diesel truck performance parts and products. Buhidar and Alaniz met while attending Texas A&M University. Alaniz’ interests in four-by-four trucks began as a child. He would go off-roading on the beaches of South Padre Island with his father in an ‘85 Ford F-150 that had been enhanced with “big rims and big tires.” The business partners pride themselves in having a combined 15 years of experience in the diesel performance industry. Together with their highly experienced team, Buhidar and Alaniz perform all of the custom enhancements from their 10,000 square foot facility.
