Price per rod-1275cc larger 6.35mm diameter push rod. Sold per single rod and 8 required per engine.
The larger diameter improves push rod rigidity as much as possible
without having to modify the block/head push rod ports. This in turn better translates the cam lobe profile at the valve which therefore improves engine performance. Particularly where up-rated/stronger valve springs are used.
For 8 port head correct length rods see
C-AEG583 and
C-AEG583EVO.
