Brand new Hyway 46mm cylinder with pop up extra compression piston kit. Fits Husqvarna chainsaw models 51, 55, 55 Rancher.

High quality kit that comes with a 1 year guarantee.
The kit includes 46mm Nikasil plated cylinder, pop up piston, Caber ring (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: the muffler slots require slight enlarging with a round file to fit the muffler bolts properly
