Good To Know

Q: How do I know this flange fits my sled? A: Check that your machine is a 2004 or 2005 Polaris Switchback 600 and that the existing flange is marked or listed as 1253423. Comparing the mounting bolt pattern and carburetor throat size to your old part confirms the match.

Q: Why replace a carb mounting flange? A: Rubber flanges dry out, crack, and leak air over time, which causes lean running, rough idle, and hard starting. A fresh flange restores a reliable seal between the carburetor and the engine.

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