Wiseco Tracker Piston Kit 10.5:1 STD - 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 V-twin engines with a 4.375-inch stroke, 96–103 cubic inch displacement, and a 10.5:1 compression ratio. Its forged construction and ArmorGlide skirt coating ensure durability and reduced friction, making it a solid foundation for a performance-oriented rebuild.
