Manley’s Valve Train Components
allow your engine achieve its
maximum performance potential.
Weight is the enemy
offers TensileMax steel retainers
that are nearly as light as standard
titanium retainers but much harder
(Rc 52-54) for improved wear. H-13
tool steel retainers, which Rockwell
at 56, are 33% lighter than standard
10° steel retainers.
Titanium Saves weight
Compact Dual Valve Springs
Among other things, it hampers
valve train kinetics and has an impact
on reliability. That’s why Manley’s
engineering team strives to make
the company’s products as light as
possible —without sacrificing durability.
Manley one -piece forged titanium
valves are preferred by leading engine
builders and have an outstanding
track record of reliability. And Manley
makes a good thing even better
through offering custom hollow stem
titanium intakes and “thin film” seat
face coating (choose between CrN
or NANO) for improved lubricity, wear
resistance and a better seal between
the seat and face.
Reduced Mass Stainless
The Pro-Flo design, originated by
Manley, improves low-lift flow and
also has less mass than valves with
conventional stems. They’re part of the
industry’s widest selection of forged
stainless steel valves.
Retainers are another area where
Manley has pared weight to improve
RPM potential. In addition to FEAdeveloped titanium retainers, Manley
Even more weight savings are
available through replacing triple valve
spring setups with Manley’s new
generation of compact, lightweight
NexTek® double springs. Of course, like
all other Manley NexTek® springs, they
have amazing load retention properties,
and they’re backed by Manley’s NHRA
Major Sponsor contingency program.
Optimum Pushrod Size
Manley’s one-piece swedged-end
4130 chrome moly pushrods come
in no less than five different o.d. and
wall thickness combinations to assure
you’re achieving valve train stability at
the lightest possible weight.
And There’s More…
Add special valve locks, a wide
assortment of spring cups and i.d.
locators, shims and special cylinder
head prep tools, and you’ve got
everything you need for the best valve
train on the market today.
