Roller-tip rocker assembly. 1.5 Hi-Lift for 1275cc big bore engines only.

Craddle type with upgraded shaft size to improve rigidity. Stronger adjuster screws and nuts.Ensure you tighten down all posts equally to eliminate stress fractures on shaft

To use on small bore heads it is necessary to re-arrange the rockers to line up the tips with valve stems.

The ultimate lightweight alloy valve gear giving maximum efficiency cutting down side loading on valve stem, reducing friction and wear whilst increasing rigidity. The 1.5 hi-lift keeps valves open approximately 20% more at any given point, although opening and closing periods remain the same, and vastly improves volumetric efficiency and, therefore, power output. The alloy rockers have hard chrome roller tips and original bronze bushes for a competition thick-wall Mini shaft, standard adjuster screws and nuts are also employed. These combine in a high quality yet economical roller rocker set, as the roller tip is the most important factor to reduce valve and guide wear when using modern performance cams. The set comes with 8 rockers, adjuster screws and nuts, competition thick-wall shaft and steel pedestals. Also see spacer kit C-AEG392.
