Racing Transmission Shafts & Gears

Many racing enthusiasts, above all, try to modify their motors to gain more power. After upgrading all bolt-on components and internal engine parts, the user may end up in a situation when the motor produces more torque than the stock transmission can handle. To make sure that you don’t end up with broken shafts or sheared teeth on your gears, consider upgrading your stock gearbox with our racing transmission shafts and gears. These products are designed and manufactured by reputable companies with great precision to provide reliable and efficient performance in a variety of driving conditions and applications.

The shafts and gears offered on our website can tackle much harder tasks and withstand higher stresses than their stock analogs. Also, the right components can allow you to accelerate better and deliver engine power to the ground more efficiently and achieve better results on the street, strip, or track. For example, torsional input shafts made from extremely resilient and strong steel can twist a little at the peak load and then return to their initial state thus reducing shocks and preventing damage to the gear train. Note that aftermarket racing input shafts for automatic transmissions must ensure proper lubrication of the gearbox and sufficient converter charge pressure.

Our online store offers a wide range of straight-cut racing gears for manual and automatic transmissions featuring better efficiency than their helical counterparts since they don’t waste engine power on producing axial loads. For fine-tuning the performance of your gearbox, you can install planetary gear sets offering different gear ratios for faster take-offs, higher top speed, or increased low-end power. These products are available in a variety of ratios, strengths, and lengths. Besides gears and shafts, here you can find a variety of related components, such as spacers, springs, clutch drums and hubs, bearings, shift forks, synchro sleeves, and much more.
