The HEMI rocker stud and nut assembly allows for improved clamping load, adding up to a rigid, stable and high revving valve train assembly. It saves threads in aluminum heads, especially in race applications that see frequent disassembly. The stud kit aids during installation of shaft mount rockers by accurately guiding the rocker arm assembly into position.
The 12 point flange nuts provide clearance to rockers for maximum lift potential while a rounded nose on top of the stud prevents cross threading of the nut during assembly. Manufactured from grade 12.9 hardware, the high-strength studs help prevent thread fatigue and pulling of threads in aluminum cylinder heads.
