Q: Does this pan require vehicle modifications?
A: No. It installs directly in the factory location with the included hardware and gasket.

Q: Is the magnetic drain plug included?
A: Yes, and it is designed to capture harmful metal particles to protect your engine.

Q: Can I install an oil temperature sensor?
A: Yes, the oil pan includes a 1/8” NPT port for optional sensor installation.

Q: Does the fluorine rubber seal need frequent replacement?
A: No. Unlike copper seals, the fluorine rubber gasket is reusable and only requires replacement when necessary.

Q: Will the added capacity affect clearance?
A: The design maintains compatibility with the GM 6.6L chassis, but care should be taken to confirm sufficient clearance during installation.

Q: How does it perform under towing conditions?
