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.

Increase Service Life & Get Better Sealing
With CrN or DLC Seat Face Coating
• High hardness and lubricity
prevents seat wear

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.
