Replacement Piston Rings for 2-Stroke Engines
These LAHDEK piston rings suit petrol chainsaws, trimmers, brush cutters and mowers. Each ring measures 31mm by 1.5mm and the pack contains two pieces. They are sold as new replacement parts for a wide range of models.
Behaviour Under Sustained Load
The rings maintain a seal during continuous 2-stroke operation at typical cutting speeds. Heat expansion is managed by the standard cross-section. No endurance data or rpm limit is supplied.
Compatibility Check Before Ordering
Verify that your engine uses a 31mm bore with a 1.5mm ring groove. Confirm the piston takes two rings and that the part number matches your service manual. Buyers needing a different bore size or ring count cannot use this set.

Questions about this item
Do the 31 mm x 1.5 mm rings generate extra heat during long cutting sessions?
These piston rings are passive metal components; they add no measurable heat beyond normal engine friction.
Which existing engine parts must match the 31 mm bore and 1.5 mm groove width for these rings to seal?
The cylinder bore must be 31 mm and the piston groove 1.5 mm wide; the piston and cylinder must already be in serviceable condition.
Will these rings fit a 2-stroke mower engine that currently runs a different brand of 31 mm ring?
Yes, provided the bore is 31 mm and the groove accepts a 1.5 mm ring, brand makes no difference to fit.
