ROLLER ROCKERS 1.7

Roller rocker assembly. 1.7 lift, big bore set.
Possible to use on small bore engines (full race only) but rockers need to be rearranged to line up with the valve stems.
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.
The 1.5 lift vastly improves volumetric efficiency and therefore power output. When fitted to a 1275cc or large bore engine it gives the equivalent of fitting a mild camshaft. The alloy rockers have hard chrome roller tips and dual needle roller bearings that sit on a special rocker shaft. The rollers are offset in the arms to link up with the valve stems in large bore heads. A budget type using identical rocker arm castings but with original bronze bushes is also available in 1.5 ratio only2
