BIG BORE CYLINDER KIT STIHL/HUSQ

Big Bore Piston and Cylinder Kits for select professional Husqvarna? and Stihl? chainsaws. The pistons and cylinders in these kits have been oversized to provide more displacement, which can result in a power boost. Kits include a piston, rings, wrist pin with clips and a cylinder. These kits have the same 30-day warranty from the date of purchase as the original equipment manufacturer versions. This warranty covers the cylinder kit only. A gasket set and piston ring clamp set is recommended when assembling Big Bore Piston and Cylinder Kits.
