Product description

These shafts are equipped with bolt mounting on the ends instead of the (quickly breaking and jumping away) mounting clips, thus creating a solid rocker arm shaft. The shafts are designed for the original rockers or the 1.25 to 1 rockers.

Comes in pairs, including mounting hardware and adjustment rings to properly position the rocker arms above the valves (reducing wear on the valve clearance adjustment bolts and valves).

You should use these rocker arm shafts if you have heavier valve springs fitted and/or driving at high speeds.

Adjustment rings
It is necessary to adjust the rocker shafts properly. On the one hand in height, to ensure that the oil channel in the adjusting bolts is in line with the channel in the rocker arm when the adjusting bolts with pressure balls #1784 or with pressure feet #3784 are used, but also to properly adjust the valve geometry. On the other hand, to adjust the lateral (axial) play of the rocker arm on the shaft and to ensure that the rocker arms extend above the valve stems at the correct location. There are a number of adjustment rings supplied for lateral adjustment but in most cases these will not suffice. The adjustment plates for the height adjustment are not included at all, you will have to order these extra anyway. It is advisable to take a number of sizes of each kind so that you do not end up with a shortage of adjustment plates and rings. The number supplied per size is indicated in brackets behind the name.
