These High Energy Die Cast Aluminum Roller Rocker Arms for Chevy V8 396-454 applications are perfect for street and moderate race use. With a 7/16" stud diameter and 1.7 ratio, the die cast, larger-than-stock body of the rocker arms is made of aluminum for superior strength with light overall weight. High Energy Die Cast Aluminum Roller Rocker Arms from COMP Cams are an affordable option that feature a die cast, aluminum body with a needle bearing fulcrum and roller tip. Designed to be stiffer and more durable, these cost effective rocker arms are capable of providing added valve lift while withstanding the rigors of a performance application. Their specially engineered fulcrum and roller tip create far less friction than sliding factory models to lower oil temperatures, thus improving both response and horsepower. Snap rings are used to hold the trunion and bearings locked in place.
- Excellent replacement rocker arms for engine rebuilds with a stock or High Energy Camshaft
- Help to eliminate noise and slop associated with worn or high mileage stock rockers
- Include adjusting nuts and pivot balls where required
- Feature a long slot for higher than stock lift Camshafts
- Valve train deflectors recommended when using a high volume or high pressure oil pump
- Nitrided rockers are designed for higher valve spring pressures and hardened pushrods
- Nitriding increases hardness, thus improving durability and longevity of rocker arms
