The Brian Crower BC0109 stroker kit is a strong bottom-end upgrade for Mitsubishi 4G63 and Evo 7-bolt engine builds needing more displacement, forged strength, and custom piston options. This 2.40L rotating assembly includes a 4340 billet 7-bolt crankshaft with a 102mm stroke, BC ProH2K connecting rods, and custom pistons available in your selected bore size and compression ratio. Built for high-performance 4G63 turbo applications, this kit is a solid foundation for street, drag, track, and race builds where increased stroke, durability, and precise engine setup matter. ACL Race bearings are available separately.
