Description
If you’re pushing your Twin Cam engine past 5500 RPM, stock hydraulic tappets become a liability—they can’t keep up with RPM demands and create reliability issues that limit performance. The JIMS Hydrosolid Tappet solves this problem by seamlessly transitioning to solid operation at elevated speeds, delivering 3-6 additional horsepower while protecting your engine from hydraulic pump failure. For serious riders and racers building high-output motors, this is the tappet upgrade that unlocks real performance gains without compromise.
