Dodge Viper Billet Roller Rockers

Lightweight roller rockers provide more precise valve timing for horsepower improvement over stock. Conservative performance gains are 17-20 RWHP and RWTQ on a naturally aspirated engine. Gains may be higher on earlier Vipers that had a 1.5:1 ratio in stock form and in forced induction applications (typically 26 RWHP). The set of roller rockers will come with all mounting hardware and will require aftermarket pushrods. Harland Sharp has over 40 years of experience in building roller rocker arms. We try to make them affordable, adjustable, and easy to install for the average enthusiast. Tests show reductions in weight, friction, heat, and valve guide wear and increases in horsepower and performance through more accurate ratios and valve timing. The Dodge V10 rocker arms are a direct bolt on. Fully adjustable for use with larger cams No machining required 1.7 Ratio
