VALVE TRAIN<br />
Valve Spring Retainers<br />
Steel Valve Spring Retainers<br />
STANDARD CONFIGURATION<br />
<strong>Crane</strong> <strong>Cams</strong>’ steel valve spring retainers are precision manufactured from high quality bar<br />
stock steel, heat treated for maximum strength and durability, and black oxided for corrosion<br />
resistance. <strong>Crane</strong> steel retainers are made for 8mm, 5/16”, 11/32”, and 3/8” valve stem diameters<br />
with 7° taper and are compatible with either <strong>Crane</strong> stamped steel or machined steel valve<br />
stem locks. Retainers for 3/8” diameter valve stems will also accommodate <strong>Crane</strong> Multi Fit steel<br />
locks (All locks sold separately. See pages 360-361). We additionally offer retainers designed<br />
for specific engine applications.<br />
MULTI FIT STYLE STEEL RETAINERS WITH 7° TAPER<br />
The Multi Fit style has the same basic tapered I.D. dimensions as a normal 7° steel retainer made for a 3/8” valve stem diameter,<br />
and are manufactured from premium quality bar stock material. By using the special thick Multi Fit Valve Stem Locks,<br />
these retainers can be used with either 5/16” or 11/32” valve stem diameters. By using <strong>Crane</strong> <strong>Cams</strong>’ 3/8” machined steel<br />
valve locks, these same retainers will accommodate a 3/8” valve stem also. Locks are sold separately, see pages 360-361.<br />
MULTI FIT STYLE STEEL RETAINERS WITH 10° TAPER<br />
Our Multi Fit 10 degree retainers and locks differ from the conventional 10 degree items, as we use a smaller outside diameter<br />
lock, enabling the retainer to have a greater cross section in the critical area separating the inner spring steps from the<br />
tapered center hole. This provides superior strength and stability when compared to the competition, and these retainers<br />
are designed for use only with our Multi Fit locks. Compatible locks are offered for 8mm, 5/16”, 11/32” and 3/8” valve stems<br />
in standard square groove and bead groove configurations. Optional assembly height locks are also offered, see pages<br />
360-361.<br />
Titanium Valve Spring Retainers<br />
The lighter your valve train components, the quicker the engine will rev. Titanium retainers are<br />
40% lighter than steel. All <strong>Crane</strong> titanium retainers are machined from certified Americanmade<br />
bar stock. Beware of the recent influx of inexpensive “titanium” retainers. These are probably<br />
made of inferior imported material, and will not pass certification standards.<br />
MULTI FIT STYLE TITANIUM RETAINERS WITH 7° TAPER<br />
The Multi Fit style has the same basic tapered I.D. dimensions as a normal 7° steel retainer<br />
made for a 3/8” valve stem diameter, and are manufactured from premium quality bar stock<br />
material. By using the special thick Multi Fit Valve Stem Locks, these retainers can be used with<br />
either 5/16” or 11/32” valve stem diameters. By using <strong>Crane</strong> <strong>Cams</strong>’ 3/8” machined steel valve locks, these same retainers will<br />
accommodate a 3/8” valve stem also. Locks are sold separately, see pages 360-361.<br />
POSI-STOP DESIGN TITANIUM RETAINERS WITH 7° TAPER<br />
Absolutely The Strongest Titanium Retainer/Lock System Available! Proven In Competition<br />
By Nationally-Known Pro Stock, Top Fuel, Funny Car, And Short-Track Race Teams!<br />
<strong>Crane</strong> <strong>Cams</strong>’ Posi-Stop titanium retainers feature the patented stepped design that reinforces<br />
the bottom of the retainer. This both significantly increases the integral strength of the<br />
retainer, and eliminates the valve lock’s ability to pull through the bottom of the retainer.<br />
“Posi-Stop” retainers are made for 5/16”, 11/32”, or 3/8” valve stem diameters with 7° taper, and<br />
come with matching <strong>Crane</strong> machined valve stem locks.<br />
MULTI FIT STYLE TITANIUM RETAINERS WITH 10° TAPER<br />
Our Multi Fit 10 degree retainers and locks differ from the conventional 10 degree items, as we use a smaller outside diameter<br />
lock, enabling the retainer to have a greater cross section in the critical area separating the inner spring steps from the<br />
tapered center hole. This provides superior strength and stability when compared to the competition, and these retainers<br />
are designed for use only with our Multi Fit locks. Compatible locks are offered for 8mm, 5/16”, 11/32” and 3/8” valve stems<br />
in standard square groove and bead groove configurations. Optional assembly height locks are also offered, see pages<br />
360-361.<br />
CONVENTIONAL DESIGN TITANIUM RETAINERS WITH 10° TAPER<br />
Our conventional 10 degree titanium retainers are made from premium quality titanium alloy bar stock that is precisely<br />
machined on our own automated equipment. Each retainer is carefully quality control inspected for precision and accuracy.<br />
These retainers are available in the popular conventional 10° design, for strength and light weight. Locks are sold separately,<br />
see pages 360-361.<br />
