These Proform rocker arm studs eliminate the need for press-in studs that pull out in high-rpm and high valve spring pressure applications.

They are manufactured from high-quality hardened alloy steel and finished in durable black oxide, and they're precision-machined and heat-treated for reliable operation with today's advanced valvetrains.

These Proform rocker arm studs' specially machined threads and shoulder areas ensure firm and positive rocker arm support with minimal movement or distortion.
