ROCKER ARM STUDS
• High EnergyTM and Magnum series studs work well in applications with moderate lifts and spring pressures.
• When ultimate strength is required
the Hi-TechTM Race Stud is the answer.
This stud has a thin jam nut for rocker clearance, rolled threads and a ground-flat top.
• The larger diameter jam nut spreads the load over a larger area.
GUIDE PLATES
• Designed using stereo lithography techniques for accurate fit; hardened and black oxide finished.
• Feature exact stud placement and rounded contact points.
