Discover Our Cummins Marine Diesel Piston Kits and Accessories

Our collection of piston kits includes products that cover a wide range of replacement situations. Customers who need a full replacement and those looking for a partial replacement can find something to meet their needs. We sell a variety of Cummins piston kits and accessories, including:

  • Full piston kits: One of our Cummins piston kits typically includes a piston, pin, pin retainer and ring set to replace one or more pistons. Remember to pay attention to how many units your kit will service and buy enough to fix all of the pistons you want to restore.
  • Piston cylinder liners: A piston's cylinder liner fits between the cylinder block and piston to protect these parts as they operate. As you figure out your components checklist, we recommend that you check if you also need a new cylinder liner.
  • Piston ring sets: When you need to replace your engine's piston rings, you can buy these parts in a standalone kit. With new piston rings, you can create a tighter seal to prevent gas leaks.
