426 HEMI High Compression Stroker Kit

The Modern Muscle Performance (MMX) 426 High Compression HEMI 6.4L Based Stroker Kit is engineered to significantly increase the cubic inches of your 6.4L HEMI engine. This premium rotating assembly is built using custom-specification forged M142 pistons, manufactured by MAHLE Motorsports, incorporating features that differentiate MMX piston and rod solutions. Key features include a Manley or Molnar Forged 4.050 Stroke Crankshaft and M142 Material or 4032 Alloy Pistons with enhanced durability. The kit also includes file-fit premium rings, and choice of Power Adder 6.125" Center to Center Molnar Technologies Forged Rods or Manley H Beam Rods. This configuration achieves an 11:1 compression ratio, with variations depending on the head gasket used (11.3:1 with stock heads, 11.0:1 with .040 Cometic gasket, and 10.8:1 with .054 Cometic gasket). The valve reliefs are deep enough for up to 2.200" intake and 1.650" exhaust valves.
