More RPM !

Manley ’ s Valve Train Components allow your engine to achieve its maximum performance potential .

Weight is the enemy
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 .
Titanium Saves weight
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 .
Lightweight Retainers
Retainers are another area where Manley has pared weight to improve RPM potential . In addition to FEAdeveloped 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 . H-13 tool steel retainers , which Rockwell at 56 , are 33 % lighter than standard 10 ° steel retainers .
Compact Dual Valve Springs 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 .
