COMP Cams shaft mount aluminum rocker arms are one of the most cost-effective ways to increase horsepower. These shaft rockers were designed using the latest in computer software and engineering. They center the roller tip over the valve tip at the correct time so that the roller tip is never more than 0.020 in. off-center of the valve tip. At the greatest load point, the roller tip contact is on the center of the valve. At valve closing, the roller tip contact is slightly behind the valve centerline. When the valve is at full open, the tip contact is slightly behind the centerline of the valve. The results are more horsepower and better performance.

Rely on Jesel Pro Aluminum Series shaft rocker arms to move you into the winner's circle. Their custom blended 7000 Series aluminum alloy allows for an extremely durable and lightweight valvetrain assembly with a tensile strength at 300 degrees to far exceed that of less expense, industry-standard 2024 alloys. Jesel Pro Series rocker arms have profiled rocker tails and clipped-pin nose rollers, and they are shot-peened for increased resistance to fatigue failures. They are offered in standard slot, Mohawk beam, and solid body styles, as well as different ratios individually and in sets. Features of Jesel Pro Aluminum shaft-mounted rockers: * Longer rocker arms provide higher rocker ratios * Proper travel arc geometry * Enough rocker-to-valve spring clearance to run big race springs * CNC-machined aluminum rockers are extra rigid to insure true rocker ratio * Shaft mounting reduces reciprocating mass for high rpm use * Easier access to valve springs, lash caps, retainers and locks * Longer valve spring life

For those of you that feel most confident running a steel-based valve train, look no further than the collection of Crower stainless steel shaft-mounted rocker arm systems. Every configuration has been rigorously scrutinized to offer extreme rigidity and accuracy while optimizing the moment of inertia phenomena condition. Crower engineers made ease of installation and maintenance a top priority--so you'll never waste a moment when time is critical at the track. These stainless steel shaft rocker systems are a perennial favorite of dirt late models and marine endurance competitors. Sustained high temperatures have little effect on the strength properties of stainless steel so components made from this material typically have a longer life expectancy than similar components made from aluminum. All Crower shaft mount rocker arms are available with Crower's needle bearing roller tip option. They greatly reduce friction for added horsepower and decreased valve guide and valve stem wear. The lighter tips deliver greater valve control for increased rpm and improve valve spring longevity by decreasing heat compared to traditional non-needle designs.
