ROLLER ROCKER ASSEMBLIES
“Achieve More Performance With a Roller Rocker Kit.”
Roller rocker assemblies are available for 1296 and 1500 Spitfire engines. For the
earlier 1147cc engines, complete assemblies are not available but a kit containing roller
rockers and a hardened shaft is available to allow you to build as assembly using your
own pedestals. Roller rockers run with needle bearings on a hardened rocker shaft. The
rocker contacts the valve stem via a roller bearing on the rocker tip, reducing side loads
which wear valve stems and guides. Stock rockers have a 1.43:1 ratio, and the higher
the ratio of the roller rockers improves engine performance by opening valves faster and
farther. This increases air and fuel flow into the cylinders and provides a net horsepower
increase of as much as 10%.
