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 delivers robust performance and reliability for your 88 cubic inch V-twin. Engineered with a 9.5:1 compression ratio and a +.020 inch oversized bore, this kit is ready for your rebuild.
