The G-Force GF-5R 5-Speed
Transmission is shown above
with the Long
Grip 5-Speed Shifter.
||The GF-5R transmission has a wide range
of applications. Some of these often include: drag racing (both clutchless
and clutch assisted), road racing, off road, and street/strip vehicles.
Like the G-101, this
transmission can be used as a 4-speed if an overdrive is desired,
or a 4th gear if 1:1 is not adequate. This transmission also has many
custom applications which may include: dragsters or roadsters, import
vehicles, salt flat vehicles, and open road racing. The possibilities
for using this transmission are virtually endless.Like all of our
models, this transmission comes with your choice of a Long
H-Pattern or Vertical
Gate shifter. An air shifter can be specified as optional for
drag racing applications as well.
| Other available options for this
model are REM® micropolished
gears, needle bearing output (with includes Mark Williams hardened
and a torsion bar. The torsion bar option is essentially what it sounds
like. This is a long bar that runs through a hollow countershaft.
This bar is connected to the input drive set at one end and to the
rear of the counter shaft at the other end via splines. The idea behind
the torsion bar is that the power transfers through this bar and consequently
twists it slightly, but only for an instant. This power is then transferred
to the counter shaft itself (the outer tube), thus driving the vehicle
forward. This twisting action helps relieve some of the impact that
normally gets transferred directly to the gears. This option is mostly
utilized in considerably heavy cars (generally 3,000 lb. or more)
or cars with a very "stiff" clutch.
| Most drag racing clutches today need only a few
hundred pounds of pressure to perform well. The more the clutch pressure,
the more impact that transfers to the gear teeth. The clutch technology
utilized in a vehicle is largely dependent upon the type of transmission
used. When using a high performance transmission such as the GF-5R,
it is very important to consider these things.
The GF-5R 5 speed transmission is most definitely a high performance
unit. This transmission has benefited from years of development
and has proven its' worth in the realm high performance. With proven
excessive horsepower handling capability and low price as compared
to its' closest competitors, it is without question the best value
in 5 speed racing transmission technology.
