G-101

The G-101 racing 4-speed transmission is the ultimate in 4-speed performance. This transmission can be built as a clutchless or clutch assisted model and has a wide range of applications. The G-101 is primarily used for drag racing only, but can also be used in street/strip vehicles. This transmission is capable of handling the power of some of the fastest Super Stock, Stock, NMRA, NMCA, NSCA, and import vehicles. The G-101 has virtually endless drag racing applications where a 'super duty' clutch assisted transmission is required. The gears in this model are extra wide to ensure long gear life and optimum performance. This transmission can be used with a Long H-pattern or Vertical Gate shifter. Many of the Super Stock and NSCA competitors have switched to the G-101 for improved reliability.

The G-Force G-101 4-Speed Transmission is shown above with the Long V-Gate Shifter.

Available options are a magnesium case option and needle bearing output. The magnesium case option saves approximately 6 lb. over the aluminum version and the needle bearing output is ideal for nearly any application that involves an exceptionally high-reving engine and/or excessive horsepower.

Excessive power handling is what the G-101 is all about. This transmission is without a doubt the best value in 4 speed transmission technology due to its' exceptional power handling and low price. Available with nearly any ratio you can think of, the G-101 is the ultimate 4 speed. For 4 speed applications in excess of 1000 horsepower the GF-5R model is recommended.

GF-5R

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 a magnesium case (which saves 10 pounds), REM micropolished gears, needle bearing output (with includes Mark Williams hardened yoke), 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.
