Brand new Hyway Titanikel Big Bore 52mm cylinder with pop up extra compression piston kit. Fits Stihl chainsaw models MS440 and 044 (later models with 12mm wrist pin). New Titanikel plating has lower friction.

High quality kit that comes with a 1 year guarantee.

The kit includes 52mm Titanikel plated cylinder, pop up piston, 2 Caber rings (made in Italy these are the best rings you can get), wrist pin, circlips, gaskets, and Oregon spark plug. 
These pop up pistons are impressive, they normally add at least 10 psi compression over the original style flat top piston. More compression equals more power.
*Please note: Does not fit older model 044 with 10mm wrist pin
