G-Force T-56

After months of testing, G-Force is proud to introduce the latest product in our ever-expanding high performance transmission lineup. The G-Force T-56 upgrade kit is now in production and available for any T-56 variation. Whether you have a power adder or just big cubic inches, we know this is what you have been waiting for. We have TRUE bolt-in kits to fit Viper, Corvette, Camaro, and Cobra applications along with custom installation kits that allow for an even wider range of installations. With the optional G-Force mainshafts, these kits have the ability to handle approximately 900* horsepower and 800 ft-lb. of torque depending on the application. Our kit combines the strength of a full-out race transmission with the factory look, drivability, and fit of an OEM installation. The G-Force T-56 conversion requires no case, tailhousing, or shifter modifications to your existing T-56. This means that your stock mounting hardware and dimensions will be utilized. This is not a one-size-fits-all kit. We have kits specifically designed for each application including special inputs for each vehicle.

In order to achieve the exceptional horsepower and torque handling abilities this kit has to offer, G-Force has again gone back to its racing heritage. While totally reengineering the gear design and tooth profile, we also added gear width wherever possible and have gone with our vast experience in terms of material selection. We use a proven 9310 alloy material for the gears themselves and a slightly different alloy for the synchronizer sleeves and the input shaft. This means exceptional gear strength and increased synchronizer ring wear resistance. Also, gears 2nd, 3rd, and 4th all have replaceable synchronizer sleeves. If you happen to wear out the engagement teeth on the front of the gear, just replace it with a slip-in piece. There is no need to buy the gear when doing this. This concept also works the other way as well. In the unlikely event that you need to replace a gear, you only have to replace a gear and not an assembly, thus saving an additional expenditure. These kits utilize the factory overdrive gears and mainshaft while essentially replacing all the other gears and shafts in the transmission.
These G-Force T-56 kits feature helical gearing to maintain a comfortable noise level while still maintaining exceptional strength.

While slightly noisier than a stock T-56, the increased gear noise in not excessive and nothing like a straightcut, race-only transmission. We have tested slightly differing designs to come up with the best strength/quietness levels possible when dealing with the excessive power that these kits are made to cope with.
To further enhance the performance of your T-56, G-Force has come up with some additional performance options. Quicker, smoother shifting is always a plus when driving any manual transmission, and this is why G-Force has manufactured a triple cone conversion for your Viper, Camaro, or Cobra. While normally found only in the C5 Corvette applications, this conversion allows for the installation of the superior shifting triple cone synchronizer setup to be installed into any T-56. The T-56 normally comes with triple cone synchronizers only on 1st and 2nd gears, but our kit allows for the use of the triple cone setup in 3rd and 4th gears as well, greatly enhancing the shifting quickness of these gears. This kit includes the 3rd gear for the mainshaft, the input shaft with the input gear, the 3rd and 4th triple cone synchronizer and hub setup, and a special G-Force mainshaft. If you own a C5 Corvette, you already have this setup in your transmission. We do, however, have upgraded mainshafts made specifically for the C5 transmission. If you are looking for a transmission to be used in a project car or just want to trade in your worn out T-56, G-Force can build you a complete unit with our gear kit already installed. We can use a new or remanufactured core depending on what you would like.
*Obviously, power and torque ratings vary more or less depending upon weight, clutch, tire, RPM, etc.

 

 

GF-2000

The GF-2000 transmission is used solely for clutchless applications. This transmission is ideal for, but not limited to, Pro Import, Outlaw/Modified Import, Pro Stock, Competition Eliminator, or any of the various NMCA, NMRA, or other 10.5 inch tire muscle car applications. This transmission features a more internal bearing supports than any other racing transmission on the market today. Generally, the GF-2000 is used as a 5 speed, but it can also be build as a 4 speed depending upon the desired application. The GF-2000 and the GF-5R have many of the same applications where a clutchless drag racing transmission is needed.

The most significant advantage of the GF-2000, however, is its' strength. While the GF-5R is capable of handling 1,300 or more horsepower, depending upon application, the GF-2000 can handle approximately 25-30 percent more power in the same vehicle. There is also a greater selection of ratios available for the GF-2000. While most enthusiasts do not need this extra horsepower and ratio capability, the GF-2000 makes them available for those that do. The available options for the GF-2000 include a hollow mainshaft and counter shaft, titanium shifter, and REM micropolished gears. The titanium shifter option saves approximately 3 lb. and the hollow mainshaft and countershaft saves approximately 4 lb.

The GF-2000 clutchless 5 speed is the latest development in transmission technology. Developed specifically for professional Pro Stock teams, this transmission has endured countless hours of research and development and an equally rigorous testing agenda. It has now been made available to the general racing public to further reinforce the fact that G-Force is committed to bringing the best possible products to the racer.
