LAHDEK Piston Ring Kit for Husqvarna Chainsaws

This kit contains six replacement piston rings sized 50mm by 1.2mm. It is designed for Husqvarna models 362, 365, 365XP, 371, 372 and 372XP. The rings replace original part number 11280343000 on two-stroke petrol chainsaws.

Suits owners rebuilding the listed Husqvarna saws

The set matches the bore and groove dimensions for the models named above. It is not for saws with a different piston diameter, a different ring thickness or a different groove count. Buyers who need rings for other brands or other Husqvarna series should verify the part number first.

Critical spec: 50mm bore with 1.2mm ring thickness

These two measurements decide fitment on the 362, 365, 371 and 372 engine families. If your piston bore or ring groove differs from these figures, the rings will not seal correctly. Always confirm the original part number 11280343000 before ordering.

Questions about this item

Is the 50 mm × 1.2 mm size the only option in this kit?

Yes, the kit contains six rings all machined to 50 mm bore diameter and 1.2 mm thickness.

Will these rings restore full compression on a 372 XP saw?

They replace Husqvarna part 11280343000 and fit the 372 XP, so a fresh set returns the cylinder to factory sealing specs.

Do the rings work with the original 2-stroke groove design?

The rings are cut for the standard 2-stroke piston grooves used on the 362, 365, 371 and 372 series engines.
