About this kit

These Husqvarna backpacks share one carb body across a surprising number of models, which makes finding the right part easy. Ours replaces 581155801, 577144601 and 502845001, and the kit comes with two air filters matching 502844401.

The screws are adjustable, so if your engine was retuned for altitude you can match it. For units built from 2022 on, check your carb stamp first; Husqvarna changed the body.
