Leineweber - 70 Years of Camshaft
Experience for 100 years of Harley Engines
Jim Leineweber has nearly 70 years of
experience creating high performance
camshafts. Now he and his son, Justin,
are working together, continuing to
make the best possible stock
replacement and performance
upgrade Harley camshafts that have
been the hallmark of their reputation
for nearly 50 years.
With the impressive performance
history of Leineweber cams, you'd
expect Jim and Justin to be found
surrounded by sophisticated forming
and grinding equipment in some hotshot
laboratory style setting. Instead,
they work in their own machine shop
and do their spectacular grinds on
some rather unspectacular looking
equipment. Thanks to their
craftsmanship, Leineweber cams are
renowned throughout the industry.
Motorcycles are their passion and
performance is written into their DNA
- Justin and Jim just want your
customer's bike to perform exactly how
they want it to.
All Leineweber camshafts are
manufactured from heat-treated
aircraft quality materials. The gear is
pressed on in the conventional manner
and Leineweber says that its line-up of
camshaft grinds "includes designs that
produce more power than any other
cams on the market."
Leineweber camshafts are the constant
velocity type which lifts the valve very
quickly to its maximum lift. Therefore,
the valve is at or near maximum lift for
most of the duration, creating a wider
torque range. Cams with longer
periods of maximum lift will have
superior flow characteristics, and all
Leineweber camshafts have superior
duration, "offering a wider torque
range than other manufacturers."
"Whether you are looking for a bolt-in
to give just a bit more than stock,
something you can still kick start, are
preparing to race or even hoping to
have a vintage (pre 1940) special make
and model cam reground - we have
them all.
"Our grinds are considered the 'hot'
set-up among drag racers and street
riders worldwide. This is one mighty
stamp of approval, given that the
demands of the drag strip require a
cam that performs well at all engine
speeds."
Valve timing is checked at .053" and
the Leineweber range stretches from
Twin Cams with a 1.62-1 rocker ratio
right back through Evo, Sportsters,
Shovelheads, Panheads to 1-1 ratio
Knucklehead cams. They also offer a
custom cam grinding service,
restoration cams, cams for Flatheads,
and cams for supercharged and
turbocharged race engines.
Dealers worldwide can order direct
from Leineweber in California; in
Europe a selection of Knucklehead,
Panhead and early Shovelhead options
are available from W&W Cycles in
Germany.
