Limited Slip Differential for Tesla Model S/X Large Drive Unit 2013-2024

Upgrade your Tesla Model S/X with the Action Clutch ACEV-LDU Helical LSD, designed as a direct replacement for the factory open differential.

Unlike traditional limited slip differentials that use clutch plates, the Action Clutch ACEV-LDU differential features a helical gear design for smoother, more consistent performance. This design ensures that power is automatically shifted away from the slipping wheel to the one with better traction, without harsh locking or set pre-load.
With the ACEV-LDU differential, you’ll experience improved traction, minimized wheelspin, and reduced torque steer, especially in front-wheel-drive configurations. The system operates maintenance-free and uses the standard oil lubrication, ensuring long-lasting reliability.

Proven on the track, drag strip, and everyday driving, the Action Clutch ACEV-LDU differential is precision-engineered from Corus steel billets, designed with advanced CAD technology, and manufactured to ISO 9001-2008 standards for exceptional durability and performance.

KEY BENEFITS
Enhanced Driving Experience

Whether you’re on the track, at the drag strip, or enjoying everyday driving, the ACEV-LDU differential delivers:

• Maximized traction and minimized wheel spin
• Reduced torque steer for more controlled handling, especially in front-wheel-drive configurations
• Improved stability during cornering and acceleration

Maintenance-Free Reliability

The ACEV-LDU differential is built for long-lasting durability, featuring a maintenance-free design that works with your Tesla’s standard oil lubrication system. Say goodbye to frequent differential servicing and enjoy peace of mind on the road.

Helical Gear Design

Unlike traditional limited slip differentials that rely on clutch plates, the ACEV-LDU uses a gear-based system for smoother and more consistent performance. This advanced design ensures seamless torque transfer from the slipping wheel to the one with better traction, without harsh locking or the need for a set pre-load.
