Safely add more horsepower to your higher RPM levels with the simple installation of Hydro solids. Use with any cam be it solid or hydraulic, and receive 3 to 6 more usable horsepower from about 5600 RPM, to the safest RPM level possible for your valve train. Hydrosolids have a built in anti pump-up device, so the tappets will not pump-up, preventing valve contact. Sold each. Adjustable pushrods are necessary.
