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.
Unleash more power from your 88 cubic inch V-twin with the Wiseco Tracker piston kit. Engineered for a 10.5:1 compression ratio and a +.010 inch oversized bore, this kit is built for performance.
