The Hydrosolid tappets perform like a hydraulic tappet up to 5,500 rpm, then transition into a solid tappet for high-rpm stability. 🔧

When they convert to solid tappets, they add approximately three to six more usable horsepower for aggressive riding and late-stage power delivery.

They prevent hydraulic pump at high rpms and require the use of adjustable pushrods to set correct valvetrain geometry.

Made in the U.S.A., engineered for durable operation under demanding conditions.
