Our History

Jimmy McWhorter and Paul Dailey

River City Truck Parts was founded by Paul Dailey and Jimmy McWhorter on August 1st, 1987.

During the 1970’s and 80’s, Paul and Jimmy gained knowledge and experience in the diesel parts industry working various locations throughout Kentucky and Tennessee. By the mid 1980’s they identified an opportunity to venture on their own, specializing in new and used core diesel engines, transmissions, differentials, and associated parts.

In the summer of 1987 they seized upon that opportunity. Their original mission was to supply companies throughout the eastern US with quality used product and manufacturer acceptable cores. Since that time, and with a true entrepreneurial spirit, our company has outgrown three locations. Through stress, strain, trial and triumph, together we have built the company into what it is today.

Jimmy’s sons Derek and Daniel both grew up in the business and learned the industry through guidance from their father, a lot of hard work, and first hand experience. Both sons wanted to continue building on the foundation, core values, and mission that their father began.  So in 2014 they entered into a deal to retire Paul Dailey.

These days Derek and Daniel continue to grow and expand upon the dream of Jimmy and Paul’s to be the preeminent diesel core supplier in the world!
