FAQ

Q: Is this piston compatible with my Cummins B6.7 engine from a 2018 model truck?
A: This piston is designed for the Cummins B6.7 and QSB6.7 engine platforms. While we do not have specific year ranges, it is commonly used for these engine models. We recommend verifying your engine serial number and measuring the existing piston bore (STD 107mm) to confirm compatibility.

Q: What is included in the piston kit? Does it come with rings and pins?
A: This listing is for the piston itself. For a complete rebuild, you may need to order piston rings and wrist pins separately. Please check the product specifications or contact our sales team to confirm if your order includes additional components.

Q: How should I install this piston to ensure optimal performance?
A: Proper installation is critical. Ensure the cylinder bore is clean and within specification. Use a quality assembly lubricant on the piston skirt and rings. Follow the manufacturer’s torque specifications for connecting rod bolts. We also recommend replacing the piston rings and bearings during the rebuild for best results.
