Program Information It's been 50 years since Transamerican Auto Parts first entered the off road and performance auto parts scene, and since that time Transamerican Auto Parts has grown considerably through a foundation of providing dedicated service to both our customers and the off road community as a whole.Represented by a combination of online, mail-order, and face-to-face retailers with major off road parts distributor 4 Wheel Parts leading the charge, Transamerican Auto Parts looks not just to offer you the auto parts you need, but also foster the growth of the auto parts industry as a collective.Any off road parts dealer can set up shop and sell you parts, but Transamerican Auto Parts takes this a step further, looking for new and innovative ways to circulate product, increase the popularity of off roading as a sport, and take the off road industry to another level altogether.
