Most companies advertise some new space-age trick alloy, special materials, etc, that
means their springs are absolutely the best. Well, IT'S TIME FOR A REALITY CHECK!
Virtually, most of the these trick valve springs are simply normal RUN OF THE MILL
SHELF SPRINGS that are not made especially for them, just normal bulk that are
re-boxed with their name on them. There are only THREE spring manufacturers in the
U.S. and they can't all be the best.

Bob Wood of Wood Performance Carburetors, an innovator of the Knight Prowler

Camshafts, is a 2-time NHRA national record holder, Fuel Funny Cars etc. He spent
over two years in research and testing trying to find valve springs that were specifically
designed for EVO/TWIN-CAM bikes including his own KNIGHT PROWLER CAMS.
There weren't any out there to meet our criteria.

We needed a special valve spring that would meet every possible condition they were

exposed to.  From a simple BOLT-IN application, every day street and tour rider, to a
ground-pounding, tire-smoking EVO/TWIN-CAM using a 680 lift KNIGHT PROWLER CAM
for maximum street performance.

Indeed our research paid off when we discovered the coveted, well kept secret of what

particular type of valve springs are being used by most Winston Cup race teams, including
the national champ. It doesn't take a rocket scientist to figure out that a valve spring that
can run 8,500 rpm + with high lift cams for 500 miles with no signs of fatigue would be perfect
for 99.99% of our customers. Yes, we needed this particular spring to be redesigned for our
KNIGHT PROWLER CUSTOMERS. The results are ENDURANCE and LONG LASTING
performance with absolutely NO LIMITATIONS.

I won't bother you with a lot of mumbo-jumbo and rocket science that none of us

understand. We'll just show you the specs that no other spring can match.

All of our valve springs come with custom made (to our specifications) titanium retainers

with a special .070 inner-spring shelf and a zero fit inner-spring register. They are topped
off with 10 valve locks that can be used with or without lash caps.   Also included are steel
heat-treated stock diameter spring seats.

for 2004!

Requests for 200 horsepower cams and valve springs for large cubic inch Harleys 
just keep pouring in!  As we all know, our competition has never even reached
the 150 HP level we reached last year, for street bikes on pump gas. 
KNIGHT PROWLERS Never Sleep!
In order to meet future challenges we decided to release our new,
Huge .750 Lift cams with 276
duration that will again keep KNIGHT PROWLER
Cams the absolute leader for high performance street bikes for quite some time.


In order to meet this new challenge, our KNIGHT PROWLER Cams needed
a new type of valve spring to control these fast ramp-high lift cams that never
seem to run out of power.
 

Every spring that is manufactured for our KNIGHT PROWLER Cams comes
from PSI with wire that is made from the highest quality Chrome-Silicone alloys. 
The hard to find rod material for these alloys is 100% Kobe steel, long considered
necessary to manufacture the cleanest, purest valve spring available in the world.
 

Max Life Surface Preparation
KNIGHT PROWLER Valve Springs have an optional, proprietary, multi-step,
surface enhancement process that has been proven to increase a spring’s
endurance limit.  This process can be applied to any level of the
KNIGHT PROWLER series of springs. 
It is a very beneficial process for those looking for an increase in endurance
while maintaining their existing setup.
