TW Diesel, Inc. - About Us

TW Diesel, Inc. is a family owned and operated business that is a branch of Merrimack Valley Truck Service, which is a diesel equipment service center located in Tyngsboro, Massachusetts. The whole idea behind TW Diesel is to provide convenience to our customers. We thought, why should our customers come to us for service, then have to go somewhere else for parts that they need. We worked with our vendors to become “Authorized Resellers” of diesel parts for the most popular truck makes and engine types. We carry the most vital OEM diesel engine parts that keep you truck running right.

TW Diesel Customer Commitment

TW Diesel is continuing to build relationships with diesel part manufactures and vendors. We are listening to our customers so that we understand their needs.  All to make our product line more diverse, offering a larger selection to our customers.

No one likes a complex ecommerce website that you need an IT degree to navigate. How frustrating is it to shop a website and not be able to find what you need. You probably said to yourself “why can’t they make this easier?”. TW Diesel wants to make online shopping for diesel parts easy and convenient. You can find what you need on this site because it is setup like a parts catalog. Parts are all categorized by Truck Make, Engine Type, and part type. You can also use the search bar to enter the part number or the part name to search our database.

Whether you are from a Service Center or a do-it-yourself individual, we want to provide you with the level of service that deserve. We want you to be a returning customer forever. We’re dedicated to providing great service and quality products to our customers. TW Diesel is also committed to putting the customer first.
