The next generation in Raceseng Rev Rockers! Our new S1 rocker arms are the only true shaft mounted billet aluminum non-roller rocker arms on the market. They feature a arched steel tip which simulates the effect of a roller tip except it does not spin. The rocker geometry is designed to minimize movement on the valve and maintain minimum rocker mass with the industry's lowest moment of inertia.
The S1 Rev Rocker bodies are machined from USA extruded 7075 aluminum and mounted on a precision ground 1/2" diameter shaft. The use of this material in conjunction with the shaft provides for an extremely lightweight yet rigid rocker arm.
Rocker arm ratio - 1.3
