Light Weight Wins Races!
Manley Titanium Valves And Lightweight NexTek Dual
Drag Valve Springs Help Racers Become Champions!
Titanium Valves
Manley has hundreds of “shelf stock” titanium valve part
numbers covering dozens of engine and cylinder head applications. Moreover, Manley
can custom-make virtually any valve from existing “blanks” or manufacture them
from scratch. You should know that Manley has become a trusted resource for
many race teams because customer prints are proprietary and confidential.

Better Sealing With CrN or
DLC Seat Face Coating

prevents seat wear
• Prevents “trenching” of seat face for better seal

• Better valve-to-seat sealing equals
more horsepower

Compact Dual Drag Springs
The ability to replace heavy triple valve springs with compact NexTek ® Dual Drag valve springs with
the same pressure rating has proven to be irresistible for many engine builders. And in addition to
greatly reduced active mass, as well as using smaller diameter retainers, they have amazing load
retention properties. It’s a win-win deal all the way around.
