G-Force offers a street 5-speed T-5 kit for an entry level price. These kits allow for substantially increased horsepower handling capabilities while utilizing the factory T-5 location and mounting dimensions. This simplifies installation tremendously and assures the stock look for many cars if so desired. For vehicles not already running a T-5, an installation kit may be available for your specific application. While the G-Force Street 5-Speed conversion may look identical on the outside to a stock T-5, rest assured that they are vastly different on the inside.

The kits are available in synchronized and feature high nickel gears, a heavy duty 26 spline input shaft, and an available 9310 mainshaft upgrade. There is even an optional shift fork upgrade. The synchronized kit features helical-cut gears for better noise reduction while still retaining extra gear width.      Entirely new transmissions with a kit pre-installed are available if you don't already have a T-5. This assures all new parts are utilized and also gives you the peace of mind knowing that your transmission was assembled by highly skilled technicians.

If a used T-5 is available to you, it can be sent back for the upgrade installation and all worn out or broken parts will be repaired or replaced, at our discretion, with new or remanufactured parts. As long as the case is good, we can use it. Every upgrade kit even comes with the required oil. This oil must be run with the upgrade kit to insure optimum performance and durability. Also, the shifter installation on our conversions is identical to a stock T-5, so any existing stock or aftermarket shifter can be installed. The stock T-5 is rated at about 300 ft-lb of torque capacity. While this is fine for stock or lightly modified engine combinations, especially running small street tires, it isn’t generally enough for most of today’s high powered street/strip engine combinations. This is where the G-Force Street 5-Speed kit comes into play. Although we do not like to put torque or horsepower ratings on our products due to the vast differences in clutch, engine, chassis, tire, and mounting combinations, we can give a very rough estimate. There are simply too many variables to consider when trying to figure out how much power or torque a transmission will take in a particular application. Generally, it can be assumed that with the available upgraded mainshaft, the G-Force Street 5-Speed kit will handle roughly 600 hp or 500 ft-lb. of torque in a 3300 lb. vehicle running drag radials at the track with a moderate clutch upgrade. Obviously this is just a rough estimate regarding the power and torque handling capability, but it should give some idea as to what the G-Force Street 5-Speed kit will handle in your particular application. Our Street 5-Speed kits are currently available with the preferred 2.94, 1.94, 1.34, 1.00 ratios in gears 1 thru 4, and because most performance enthusiasts run a relatively steep rear gear, our synchronized kit utilizes a stock .63 overdrive in most applications, which allows the engine to turn less RPM at cruising speed. This equates to less engine wear and better gas mileage while still maintaining incredible acceleration in the first 4 gears -We currently have a 2.42 ratio available as well.
