Wiseco's Gen V LT piston lineup was purpose-built to address the unique demands of GM's direct injection architecture. The direct-injection dome profile is carefully engineered to complement the high-pressure fuel delivery system found in LT1 applications. Whether refreshing a worn engine or building for added performance, the K0454X05 provides the precision fitment and proven durability that Wiseco is known for.
