C-AHT437- ROCKER ASSEMBLY 1.3 RATIO 1275cc FULL ROLLER ROCKERS
Roller rocker assembly. Standard 1.3 lift with roller tips and bearings for 1275cc and large bore. General: The ultimate lightweight alloy valve gear giving maximum efficiency cutting down side loading on valve stem, reducing friction and wear whilst increasing rigidity. Available in 1.3 ratio lift which is standard or the 1.5 hi-lift which keeps valves open approximately 20% more at any given point, although opening and closing periods remain the same. For the small bore range, the 'S' 1.3 ratio is optimum. If running a Large cam in a 1275 we run these over the 1.5:1 to reduce spring crush.
