Better ring spacing to prevent the ring lands from collapsing under boost (about 30% wider spacing than shelf pistons)
Lateral bracing for better side support - will still clear reluctor ring with 4.000" stroke
0.205 Wall Wrist Pin
Double wrist pin oilers and banana groove
CNC lightening on the underside
*Requires 6.000" Rod with a 4.000" Stroke or a 6.125" Rod with a 3.750" Stroke
