38 mm 2-stroke piston rings

This set supplies two 38 mm by 1.5 mm piston rings built for single-cylinder two-stroke petrol chainsaws. It fits a long list of Craftsman models such as 358351143 358351063 358352181 and 358352160. The parts replace OEM reference 530029805 directly.

Package contents and fit

The pack contains exactly two rings so one cylinder can be refreshed without buying a full kit. No gaskets pins or tools are included so the installer must supply those separately. Compatibility covers the many model numbers listed above and no others.

Sizing limits and headroom

The 38 mm bore and 1.5 mm radial width suit engines machined to those dimensions only. They will not seal a larger bore a smaller bore or a different ring thickness. Buyers whose saws use a different piston diameter or a four-stroke design must look elsewhere.

Questions about this item

When should I replace the 38 mm × 1.5 mm piston rings on my Craftsman chainsaw?

Replace the rings when compression drops below specification, the piston shows visible ring-groove wear, or the engine smokes excessively and loses power under load.

What is the first sign the rings are worn during a long cutting session?

A steady loss of compression that makes the saw bog down in dense wood before it overheats or seizes.

How much extra heat or noise do these rings add when the saw runs all day?

The rings themselves add no measurable heat or noise; any increase comes from engine condition, fuel mix, or cooling-fin cleanliness.
