If you are making maximum horsepower and running high RPM, the last thing you want is deflection in your stud mount rocker arms. For maximum rigidity and the ability to run an offset system, a shaft mount system is the way to go.
Harland Sharp’s design uses a solid bar for the rockers to pivot on for ultimate rigidity. Many shaft rocker systems run the attachment bolts through the pivot shaft, but Harland Sharp’s design moves the fasteners to either side of the pivot bar. Harland offers custom pivot location heights to eliminate the need for shimming with the proper height.
The aluminum rockers are also outfitted with needle bearings on the trunion and have full roller tips. The rockers have the ability to be set up for a maximum offset of .550 left or right of center.
