Description

Ultra-Gold ARC
Aluminium Roller Rocker Arms

The original
Ultra-Gold Aluminium Rockers
changed the way racing and
high performance street
engine builders approached
valve train design. Now, COMP
Cams is revolutionising valve
train performance again with
the next generation of
Ultra-Gold ARC Series
Aluminium Rocker Arms,
featuring an Arced, Recessed,
Contoured design. Using
cutting-edge design
techniques and manufacturing
processes, Ultra-Gold ARC
Rockers increase engine
power, enhance valve train
stability and improve oiling.
Ultra-Gold ARC Rockers
feature a new extrusion based
on improvements developed
through FEA analysis,
resulting in an even
stronger, stiffer body
without compromising mass. A
new arced channel and
contoured top, similar to a
bridge design, give the
rockers the best
strength-to-weight ratio
possible. The body has
additional CNC contouring to
improve clearances for valve
covers and springs.
Manufactured entirely in the
U.S.A., all Ultra-Gold ARC
Series Aluminium Rocker Arms
feature a spring oiler
channel through the body for
improved lubrication. Trunion
retaining clips have been
replaced with an ultra
durable spiral lock type
clip, similar to what holds a
piston pin in place. Stress
relieving radii have also
been added to areas of the
body, trunion and pushrod
seat insert. Even the
included locking nuts (not
used in LS applications) have
been revised to increase
surface area to better
maintain lash and eliminate
wear.

Features:

• Increase
  engine power, enhance valve
  train stability and improve
  oiling
• CNC-machined,
  lightweight design removes
  weight and yields unrivalled
  quality and ratio accuracy
• Arced channel &
  contoured top give the
  rockers the best strength to
  weight ratio possible
• Precision-sorted trunion
  bearings withstand valve
  spring pressure up to 700
  lbs.
• Designed for
  high performance street and
  race engines
