High-Energy Rocker Arms
COM1212-16
Magnum Roller Rocker Arms COM1416-16
Popular with street and strip enthusiasts,
Magnum roller rockers have a low-friction roller
tip to reduce valve tip and guide wear. A stiffer
cross section prevents “flex” and increases valve lift (good for 15-30 more horsepower). Available as sets, half sets, or singles.
High-quality stamped steel rocker arms are
ideal for mild street/strip applications. Rock-
ers have elongated slots for high-lift cams and
are sold in sets of 16, with adjusting nuts and pivot balls.
