Wiseco Piston Ring Set 72.00mm (2835XC)

The Wiseco 2835XC is an XC-series piston ring set sized for a 72.00mm cylinder bore. Each kit is supplied per piston, giving you the correct top, second, and oil ring package to restore proper ring seal, compression, and oil control when you refresh a Wiseco top end. Forged-piston specialists since 1940, Wiseco builds these rings to hold their geometry under sustained high-RPM and race conditions.

Important compatibility note

These rings fit Wiseco pistons only — they will not work with OEM or other-brand pistons. Suitable for cast iron, Nikasil (nickel-ceramic), boron composite, and Electrofusion bores. Do not run them in chrome-plated bores unless Wiseco specifies otherwise, as this can cause engine damage.
