Wiseco K0159B100 Quick 8 Series Forged Piston Set BBC Brodix SR20 +23cc 1.120 CH

The Wiseco K0159B100 is a Quick 8 Series forged piston set engineered for high-performance Big Block Chevrolet engines built around Brodix SR20 cylinder heads. Featuring a +23cc hollow dome, a 1.120" compression height, and a 4.600" bore, these pistons are purpose-built for serious street/strip and drag race applications targeting a 13.7:1 compression ratio.

Crafted from 2618 high-strength aluminum alloy, the K0159B100 delivers superior fatigue resistance under the extreme thermal and mechanical loads of high-compression, high-RPM race engines. The strutted skirt design keeps weight low while maintaining stability under load. Wiseco's proprietary ArmorGlide® skirt coating reduces friction and improves scuff resistance during break-in and beyond.
