Atomic Performance Products have available a
range of heavy duty valvetrain weapons for the
Ford SOHC and DOHC 6 cylinder engines. Our range
includes H/Duty and Race Springs, Titanium and chrome moly
retainers, machined chrome moly valve locks,
stainless steel valves and anti pump-up lifters.
Chrome Moly Valve Spring Retainers
Our Chrome moly valve spring retainers are
replacements for the standard retainer, which
can fail at high RPM. They are manufactured with
an increased installed height of .050" to allow
more clearance to coil bind when used with high
lift camshafts.

Machined from 4140 chrome moly
bar stock, heat treated and black oxide coated
for durability and appearance, they will fit
stock valve springs and most aftermarket springs,
including Atomic #306800, #306801 and #306802.
#306850 - Set of 24 suit Ford DOHC 6 Cylinder
Engine
Outside diameter: 23.4mm
Installed height: 1.540 (39.10mm) +.050"
(1.25mm) greater than standard
Titanium Valve Spring Retainers
Employing the most exotic of aerospace
alloys, our retainers are direct replacements
for the standard sintered steel items which have
a tendency to fail when the locks broach their
way through. Not only are they more durable, but
when used with Atomic valve springs provide a
weight saving of 37% compared to the factory
Typhoon spring/retainer combo. The collet taper
is precisely machined to provide an installed
height of 1.490 (37.85mm) and will fit with
standard or aftermarket valve locks.

Cylinder Engine
