Delivering power is just as important as making it  that’s why Billet Design Motorsports offers expert drivetrain and transmission upgrades designed for strength, control, and long-term reliability. Whether you’re building a track monster or a high-performance street car, our certified team ensures that your drivetrain can handle the power you demand.

Dodson Motorsport Pro Dealer Certified – GTR Transmission Builds & Upgrades
As a certified Dodson Motorsport Pro Dealer, we specialize in building and upgrading GTR transmissions with world-class components. From clutch baskets and gear sets to complete transmission rebuilds, we ensure maximum reliability and seamless power delivery — trusted by serious racers and performance enthusiasts alike.

Clutch & Flywheel Upgrades
We install performance clutches and lightweight flywheels engineered for aggressive launches and smooth engagement. Whether you need a twin-disc clutch for high-horsepower applications or a street-friendly upgrade, our team matches the perfect combo for your driving goals.

Limited Slip Differentials (LSDs)
Upgrade your traction and cornering stability with a high-performance LSD. Ideal for both track and street use, LSDs help transfer power where it’s needed most — reducing wheel spin and improving control under hard acceleration and cornering.

Transmission Builds & Upgrades
From OEM+ enhancements to full race builds, we rebuild and upgrade transmissions to handle more power, shift quicker, and last longer. Our services include upgraded gearsets, synchros, shift forks, and torque converter mods for automatic builds.

Axle & Driveshaft Reinforcements
Prevent powertrain failure under load with heavy-duty axles and upgraded driveshafts. We offer custom reinforcement and installation services to keep your drivetrain solid under hard launches, drifting, or high-speed racing.
