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

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.
