Scorpion Endurance Series shaft-mount rocker arms are over-engineered so your engine’s valvetrain timing stays rock-solid race after race. That’s a really big deal at high rpm where stud-mount rockers deflect and move around, which will cost you horsepower and increase valvetrain wear.

Endurance Series rocker arms feature fully-radiused bodies CNC-machined from 7000 Series aluminum. The bodies are micropeened and blasted to reduce residual stresses, and are fitted with a needle bearing fulcrum and roller tip. Assembled rockers weigh just 120 grams and clear valve springs up to 1.650″ in diameter. China Shampoo Chair

That increases parts life and actually extends the rockers’ RPM range.
