G-Force Transmissions and Long Shifters

G-Force Transmissions and Long Shifters are the driveline components of choice for many pro stock cars and trucks as well as road race cars, off-road vehicles and high performance street machines.

G-Force Transmissions—Stronger, Lighter, More Efficient
G-Force transmissions utilize a facetooth engagement system to ensure reliable shifting at speeds exceeding 14,000 RPM. All gears are manufactured from military grade 9310 high nickel alloy steel to hold up under severe torque loads. The gears are also designed extra wide for more tooth contact, and excessive weight is removed for decreased inertia. A crowned profile is ground onto each gear after heat treating for more precise tolerances, then shot peened to add an extra level of strength.

In addition to superior gear design, the GF-5R and the GF-2000 utilize a split-case design. All transmissions are cast from high quality aluminum and magnesium alloys for maximum strength and minimal weight. Bearing supports are strategically located near each gear for the utmost stiffness, and low-friction roller bearings are incorporated in all gears and main shafts for near friction-free operation. All G-force transmissions use a Rail Fork design for smooth, effortless shifting with little wear.
