Rocker Arm Shim Kits
Rocker Arm Bridge Shim Kit
Crane’s Rocker Arm Bridge Shim Kit will correct for excessive hydraulic lifter preload on late
model American Motors V-8’s, and I-6’s, and Oldsmobile V-8’s with the bridge mounted
rocker arm assemblies. This kit will also work on the later model Pontiac 151 I-4’s with
shoulder bolt mounted rocker arms. Two different thickness shims are included to
decrease lifter preload by approximately .030”, .060” or .090” depending on the combination
of shims being used between the bridge and the cylinder head. Excessive preload
may be caused by a camshaft change, valve job, head resurfacing, etc. These shims can be
a quick and easy alternative to resorting to different length pushrods.

Rocker Arm Pedestal Shim Kit
Crane’s Rocker Arm Pedestal Shim Kit is for use on Ford engines utilizing non-adjustable
pedestal mounted rocker arms. The hydraulic lifters in these engines may have excessive
preload due to a camshaft change, valve job, head resurfacing, etc. To cure this problem,
without resorting to different pushrods, we offer this pedestal shim kit containing two different
thickness shims. These shims are placed between the rocker arm pedestal and the
cylinder head, and will reduce the preload by approximately .030”, .060”, or .090”. These will
fit the Ford V-8, 255-302, 302 H.O., 351W, 351C, 351M, 400, and 370-429-460 engines.

Needle Bearing Roller Fulcrum Conversion Kit
Crane Cams’ drop-in needle bearing fulcrum conversion kit for Ford pedestal-mount rocker
arms enables you to retrofit standard non-adjustable rockers with fully rollerized fulcrum
assemblies. This eliminates the greatest source of friction in the rocker arm, resulting in less
wasted horsepower, lower oil temperatures, greater strength and load carrying abilities,
greater vacuum at a given RPM, and better fuel economy. This kit is intended for use with
hydraulic lifter and hydraulic roller camshaft applications only.
All hardware is included: New heat treated fulcrums; needle bearing assemblies and hardened
hold-down bolts. Pedestal shim kit also included to enable you to optimize hydraulic
lifter preload for best performance and reliability. No machining required.
These will fit all pedestal mount factory rocker arms for Ford V-8 engines: 77-00 255 and
302, 77-97 351W, 70-82 351C, 351M, 400, 73-97 370-429-460. Rocker arms NOT included.
