Wiseco Tracker Piston Kit 10.5:1 +.020 - Harley Touring, Softail, Dyna
About Wiseco
Wiseco has forged pistons in Mentor, Ohio since 1941, supplying everything from factory race teams to big-bore street builds. Forged construction is what lets a V-twin survive higher compression and more cylinder pressure than the stock cast piston was designed for.
The Wiseco Tracker Piston Kit is engineered for 96–103 cubic-inch V-twin engines with a 4.375-inch stroke and a 10.5:1 compression ratio. This kit provides a robust foundation for a performance build or a reliable refresh, featuring a forged piston crown and ArmorGlide skirt coating.
