Wiseco
Wiseco was founded in 1941 by Clyde Wiseman in Cleveland, Ohio, and has since moved to Mentor, Ohio. Here it is a pistons-and-parts range: forged piston kits, ring packs, gudgeon pins and wire locks, ring compressor sleeves sized to the bore, and a few head gaskets.
The listings are detailed on the piston itself. Most give the alloy (usually 2618, with some 4032), the compression ratio, the bore and oversize, and the ring set that goes with the piston. Many name the coatings, with ArmorPlating on the crown and ArmorGlide or moly on the skirt, and some state the crown shape: dish, dome, reverse dome or flat.
Wiseco pistons are found by engine and bore rather than by car, though some also carry vehicle fitment, chiefly for Subaru, BMW, Nissan and Toyota models.
Among the piston makers on TrackToolFactory, Wiseco's listings say the most about the piston itself, which makes it easier to compare alloy, compression ratio and coating before you order.
