Specs At A Glance

Good To Know

Q: Are these belts identical to the original Thermo King belts? A: These belts are manufactured to match OEM specifications for fit and performance, but they are aftermarket replacements, not original Thermo King parts.

Q: Can I use only one belt from the set if the others are still good? A: We recommend replacing all three belts as a set to ensure even tension and prevent premature wear on individual belts.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
