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.
This Wiseco Tracker Piston Kit is engineered for 96- to 107-cubic-inch V-twin engines with a 4.375-inch stroke and a 10.5:1 compression ratio. Its forged construction, combined with force-fed pin oiling and ArmorGlide skirt coating, ensures reliable performance and reduced friction, making it a robust choice for your engine rebuild.
