The New Acura/ Honda K20 2nd Gen Roller Rocker is finally here. This Roller Rocker will handle over .650 lift @ 11,000 RPM. We optimized the fulcrum mass weight to 4 grams lighter than the 1st Gen Roller Rocker. We added additional strength towards the shaft area and reduced valve spring harmonics by 8%. If your looking to build the absolute best high lift Honda engine this Ferrea Roller Rocker will give you that extra edge against the competition.
