Aftermarket Transmission Parts

A performance transmission can be the difference between winning and losing. That’s why we offer aftermarket transmission and differential parts that provide efficient speed and torque conversions. To help keep your transmission from overheating, we carry transmission coolers—such as the HKS DCT Cooler. With this cooler kit, you can maintain your differential oil temperatures and prevent oil degradation. We also have performance clutches, clutch lines, flywheels, gear sets, and more. When you shop our online inventory, you’ll discover high-quality axles, driveshafts, and driveshaft spacers from J’s Racing, Hardrace, Spoon Sports, T1R, and EVS Tuning.
