The Pacesetters
When it comes to Pro Stock, no team was more dominant than KB Racing,
which grabbed the top three spots in 2017 NHRA Mello Yellow points.
Congrats to Bo Butner, Greg Anderson and Jason Line for their 1-2-3 finish
relying on Manley valve train components.
John Force Racing had the nitro categories covered, with Brittany Force
taking the Top Fuel championship and teammate Robert Hight nabbing the
Funny Car crown. Both Manley-equipped cars are NHRA National Record
holders in their respective categories as well.

Manley Valve Train Components Let You Achieve Optimum
Performance While Improving An Engine’s Long Term Reliability.
We know that weight is the enemy in drag
racing. But when it comes to your valve train it is
especially important. Lighter components allow
the engine to RPM quicker and achieve higher
RPM levels.
Lighter
Valves
Manley one-piece
forged titanium valves
are a great source of
weight savings. For
those wanting the
ultimate in weight
reduction, Manley
offers hollow-stem
intake valves. A “thin
film” CrN seat face
coating improves wear
resistance that
results in a better
seal.
Of course,
Manley also has the
industry’s widest
selection of one-piece
stainless steel valves, with five
models to choose from. These range from
the Budget Performance and Street series
(including the Manley-developed reduced
stem shape) Proflo to Severe Duty® and
Extreme Duty models for high temperature
reliability.

THE
Lighter Springs
Included in our wide selection of NexTek®
valve springs are compact dual spring packages
that replace heavier and larger triple springs.
they have natural frequency and employ smaller
diameter retainers for even more weight savings.
And like all other NexTek® springs they have
amazing load retention properties. And as an
added bonus, they’re backed by Manley’s NHRA
Major Sponsorship contingency program.
Lighter Retainers
Retainers are another area where Manley
has pared weight to improve RPM potential. In
addition to FEA-developed titanium retainers,
Manley offers TensileMax steel retainers that
are nearly as light as standard titanium retainers
—but much harder (Rc 52-54) for improved wear.
Special tool steel retainers (Rc 56) are one-third
lighter than standard 10° steel retainers.

3/8", 7/16") and three wall thicknesses (.080",
.135", .165") you can get sturdy one-piece 4130
chrome moly pushrods with swedged ends to

Manley’s unique LocCap™ System employs
specially designed valve locks that retain the
