Description Brand new Hyway big bore POP UP 57mm cylinder/piston kit. Fits Husqvarna chainsaw models 390 390xp 385 385xp and Jonsered chainsaw models 2188 2186. The kit includes Nikasil plated 57mm cylinder, POP UP piston with 2 ring slots, 2 rings, wrist pin, circlips, and Oregon spark plug. Great quality kit made by Hyway that comes with 1 year warranty. These pop up pistons are impressive and normally add at least 10 psi compression over the standard flat top pistons. *Please note: the original Hyway 57mm pistons required crankcase modification for proper clearance at the bottom of the stroke. Hyway has changed the design to a shorter piston so the case no longer needs clearance grinding to install this kit. We are a U.S. seller and you will get your parts quickly!
