FAQ

Q: Is this piston compatible with the Kubota V3800-T Turbo engine?
A: Yes, this piston (1J508-21110) is designed for both the naturally aspirated V3800 and the turbocharged V3800-T engine. The piston construction is robust enough to handle the increased cylinder pressures of the turbocharged variant.

Q: Do I need to replace the piston rings and pin at the same time?
A: While this listing is for the piston body only, it is highly recommended to replace the piston rings and pin simultaneously to ensure a proper seal and prevent premature wear. Please check our store for the matching ring set (1J508-21130) and piston pin.

Q: What is the standard bore size for this piston?
A: The Kubota V3800 engine uses a standard bore diameter. This piston is supplied at the standard size. If you are re-boring your engine block, please contact us to inquire about oversize (0.50mm or 1.00mm) options, which are often available upon request.
