ROCKER ARM KIT CB ADJUSTA

LUNATI/HOLLEY 86005K Features:

Lunati Rocker Arm Studs allow for the use of adjustable rocker arms, making it possible to set the proper lifter lash or preload. These studs have a thinner jam nut for improved rocker clearance but a larger diameter to spread the load out over a larger area, which reduces the chance of failure.
