Magnum
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.
