Roller Rocker Arms™ (U.S. Patent No. 4,961,407)
COMP Cams® Magnum Roller Rockers™ are the
ultimate street rocker. That’s because they
were designed with the serious performance enthusiast
in mind. They will help your engine make more power
and last longer. Magnum Roller Rocker Arms™ are:
STRONG
Magnum Roller Rocker Arms™ are made from 8620 chromemoly
steel. This makes them stronger than die cast aluminum
or stamped steel rockers. This superior material, along
with the Magnum’s super stiff design, assures maximum
lift because this rocker arm will not flex.
ACCURATE
You can’t get maximum horsepower from your engine
if your rocker ratio is off. We checked other rockers
and found rockers that were as much as .040” short
on lift. The Magnum Rockers™ are super Accurate.
They check dead on every time.
POWERFUL
The Magnum Roller Rockers™ can make between 15
and 30 horsepower over other rockers! Why? The secret
is that not only does the roller tip reduce friction,
the Magnum Rockers™ incredibly stiff design and
super accurate ratios yield more effective valve lift.
DURABLE
The roller tip design reduces friction by not scrubbing
the valve end or pushing the valve stem hard against
the valve guide. This in conjunction with super strong
design of the rocker makes for a simple, bulletproof,
and cost effective combination.
Magnum
Roller Rockers™ can be used with all High Energy™,
Magnum, Xtreme Energy™, Nitrous HP™, Xtreme
4X4™ and Xtreme Marine™ Camshafts as well
as any other hydraulic or solid cam WHERE OPEN SPRING
PRESSURES DO NOT EXCEED 350 lbs.
