Scorpion Racing Products announced the introduction of their new Endurance Series Shaft Mount Rocker Arms. According to company officials, customers have been asking Scorpion for shaft mount rocker arms, and now after exhaustive testing they are available for purchase.
Scott Reynolds, Chief Marketing Officer, states, “Scorpion takes precision manufacturing to a whole new level with its new Endurance Series Shaft Mount Rocker Arms. These rockers were designed for professional circle track, dirt track, drag racing and offshore powerboat racing engines. We believe they are the best shaft rockers available today and are built to perform at the top level, lap after lap, race after race. Plus, they are priced very competitively, and we make them in America.”
Scorpion Racing Products is well known for their superior quality valve train products produced through state-of-the-art, automated robotic manufacturing techniques, but don’t think that they’ve taken the human element out of the equation. ”Our crew is very hands-on when it comes to manufacturing our products,” says Reynolds. “Most of the people that were here when the company started in 1999 are still working here today, and they monitor our automated processes very closely to ensure absolute top quality products are made for our customers.”
Scorpion’s Director of Special Projects and Design Engineer, Zac Collins, adds, “Our new Endurance Series Shaft Mount Rocker Arms were tested in racing for several years before we released them to the public. With two seasons of racing at 8600 RPM plus…we are convinced of their ability to withstand the rigors of endurance race engines and meet the high standards we set for our products.”
The research and development process began with 3D dimension modeling and Finite Element Analysis (FEA) testing on computers. Once Scorpion’s engineers felt they had the ultimate design for a shaft mount rocker arm with endurance qualities, the manufacturing crew produced prototype components for testing. Scorpion’s engineering crew represents a team of 13 people with over 250 years of valve train engineering experience.
“One of the key areas that always poses a challenge with rocker arms is the question of performance versus temperature. Through extensive testing, we have perfected our shaft mount rockers using 7000 series aluminum for extreme racing at high RPM over a long period of time,” says Collins.
Scorpion’s Endurance Series Shaft Mount Rocker Arms are now available for 23-degree Small Block Chevrolet engine applications, and many more applications will be offered soon. Key dimensions and features include:
