Drivetrain & Sports Gearbox Parts


Optimize Your Drivetrain: More Power, More Pleasure

At Optimiz Access, we offer custom-tailored solutions for a more efficient, direct, and responsive drivetrain. Whether you are aiming to put power down on the track or achieve sharper gear selection in daily driving, upgrading your transmission system unlocks the full potential of your sports vehicle.

Key benefits of an optimized drivetrain: faster and more precise gear shifts for dynamic driving, improved torque distribution for maximum traction, enhanced component reliability, and custom setups suited to all driving styles.

Essential Components for Gearboxes and Differentials

Our lineup brings together all the essential precision parts needed to maximize power transfer to the road:

  • Clutches & Flywheels – Reinforced clutch kits, single-mass race flywheels, and high-friction materials built to handle high torque output.
  • LSDs & Differentials – Limited-slip differentials designed to eliminate wheelspin and maximize exit traction.
  • Shifters & Short Shifters – Precision short-throw shifters delivering crisp, rapid gear engagements.
  • Final Drive Gears – Shorter ring and pinion gear sets providing explosive acceleration and mid-range response.
  • Gearbox Oils & Bearings – High-performance synthetic gear oils and heavy-duty bearings engineered to protect gears under load.

We work with the most respected motorsport manufacturers in the industry: CAE Racing, Sadev, Quaife, 4Tech Shifter, Helix, SACHS Performance, and TTV Racing. We also stock OEM factory parts to cover all your routine maintenance, servicing, and drivetrain overhauls.
