NO- I here if it says Briggs & Stratton it is made in USA. If it says Polar Force By Briggs & Stratton it is made in china but the design and is up to Briggs & Stratton standards- It is NOT a clone engine.
Quote by Snowmann: The Ariens Polar Force designation has no bearing on where the engine is produced and is simply a unique trademark with a specific feature set selected by Ariens. Briggs makes snow engines both in the US and internationally at their own factories, the manufacturing plant of origin would depend on which displacement is being referred to. In my experience, the quality differences between them are nil.
