ALUMINUM "RAIL" ROCKER
ARMS |
|
 Probe Industries
self aligning "Rail" rocker arms are available as replacements
for any Ford engine using the old pressed in 3/8" rocker studs
or the newer 5/16" pedestal mounts. (Replacement screw in studs
are available separately). These rocker arms provide all the benefits
of using a true roller rocker arm, without the trouble or expense
of modifying your cylinder heads. Rail rockers must not be used
with either "stepped" rocker studs or early "slotted"
cylinder heads. |
