Key features include perfect ring groove to skirt squareness, pressure balance grooves, and a full banded skirt design for increased reliability. Each set includes 2.300" tool steel pins (96 Grams) and spiral locks. These pistons are designed for 23-degree heads with .043 x .043 x 3 ring grooves, yielding a 10.16:1 compression ratio with 64cc heads.
