Welcome to Heavy Duty Parts Company!
At Heavy Duty Parts Company, we pride ourselves on being more than just a business. We are a team of passionate individuals who have dedicated our careers to the automotive and diesel parts industry. We are a full scale cylinder head machine shop with decades of experience. Unlike massive corporations, we are a small, tight-knit group that understands the value of personalized service and attention to detail. Our journey began with two guys who shared a common frustration – the global monopoly on affordable automotive and diesel cylinder heads and parts.
Over 20 Years of Combined Experience
With over 20 years of combined experience, we have seen the industry evolve and witnessed firsthand the challenges faced by customers. High prices and limited options have long been the norm, but we knew there had to be a better way. Our dissatisfaction with the status quo led us to take matters into our own hands, and thus, Heavy Duty Parts Company was born.
Our mission is simple yet powerful: to provide top-quality automotive and diesel parts at prices that make sense. We understand the frustration of dealing with overpriced parts from the big players. It’s no secret that everyone is buying the same cylinder heads from the same manufacturers, yet the larger companies are charging exorbitant prices. We knew it was time to disrupt this unfair pricing model and bring fairness and transparency back to the industry.
Our dedication to excellence extends beyond our products.
Thank you for choosing Heavy Duty Parts Company. We invite you to explore our extensive range of products and experience the difference that comes from working with a team that truly cares. Together, we can make high-quality diesel parts accessible to all, driving change in the industry one part at a time.
