Lifetime Guarantee
Pro Magnum Rocker Arms™ are so strong that we guarantee the
rocker bodies for life against breakage.
TECH TIP:
Rebuildable! Unlike aluminum rockers, this heavy-duty rocker can
be rebuilt. We will disassemble and inspect it, then replace the
roller tip, axle, trunion and bearings to make your rockers like
new. |

Pro Magnum Roller
Rockers
Ideally suited
for serious street, bracket racing, super classes, and circle track
racing. You won't find a better roller rocker for the price.
Unsurpassed Strength
To ensure maximum durability under high-rpm operating conditions,
Pro Magnum™ Roller Rockers are built entirely from 8650 chromemoly
steel, a material three times as strong as the aluminum used in many
competing rockers. Pro Magnums are so tough, in fact, that we offer
an industry-leading lifetime warranty on the rocker bodies
themselves. And because Pro Magnums are fully rebuildable, you may
never have to buy another set of rockers again.
Less Weight Where It Counts
Our engineers used advanced computer technology (including Finite
Element Analysis) to refine the Pro Magnum™ Rocker. We added
strength where it was needed and reduced mass in low stress areas.
The result: Pro Magnum Rocker Arms™ have less weight (5%) at the
valve than most aluminum rockers. This means more rpm and valve
train stability.
Superior Design Equals Better Performance
The unique design of the Pro Magnum™ Rocker enables us to use a
larger trunion with more needle bearings. This spreads the load more
evenly and the rocker will last longer. Other features include an
integral pushrod seat that ensures accuracy and saves weight, and a
unique rocker design also provides plenty of clearance for most high
performance valve springs. |
