Brand new Hyway POP UP extra compression piston kit. Fits Husqvarna chainsaw models 371 372 372xp, Big Bore 52mm size.

The kit includes 52mm 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. 

Please ensure you have a big bore 52mm cylinder on your saw before ordering this piston kit, if you have the stock 50mm size this piston will not fit.
