C-AHT446EVO

ROLLER TIP 1.5 WITH LARGER SHAFT

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

Craddle type with larger upgraded shaft size to improve rigidity.

Ensure tightening down all posts equally to eliminate stress fractures on shaft.

The ultimate lightweight alloy valve gear giving maximum efficiency cutting down side loading on valve stem, reducing friction and guide wear whilst increasing rigidity especialy on modern performance cams.

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 set comes with 8 alloy rockers with centerless ground roller tips, fitted with stronger EN24 AEG167EVO allen key type adjuster screws and C-AHT449 multi-point nuts, competition thick-wall shaft and steel pedestals.

Ensure that the rocker cover has clearance for these rockers FP24 MPI rocker cover or Mini Spares own rocker covers will give clearance on all high lift rockers.
