Brand new Hyway POP UP extra compression piston kit. Fits Husqvarna chainsaw models 365 x-torq and 372xp x-torq, standard 50mm bore size. Does not fit the older 365 and 372 non x-torq saws (if your decompression valve is on the top of your cylinder its an x-torq, if its on the side its not an x-torq)

The kit includes 50mm POP UP piston, Caber piston rings (made in Italy, these are an upgrade over the Hyway rings), wrist pin, and circlips.

Do you want to add power to your saw without spending money on expensive porting? This POP UP extra compression piston from Hyway will generally add at least 10 psi compression over the stock design piston. More compression equals more power. Caber piston rings are the best you can get and ensure reliable performance. 

1 year warranty against defects on this Hyway piston kit.
