aluminum rockers are used around the world by professional racers,
engine builders and hot rod enthusiasts, offering outstanding power and
performance advantages for street, strip, and track applications. Made
from high strength 6061-T6 aluminum extrusions, each piece is precision
CNC machined and finished by hand to ensure that our customers receive
the very best PRW has to offer. PRW stud mount aluminum rockers are
specially machined to allow for larger springs and retainers with
full-cage friction reducing needle bearings for added durability. The
nose rollers and shafts are Cr40 steel, heat-treated and hardened to
minimize the wear that naturally occurs between the roller tip and the
valve stem.
