Wavetrac Differential Porsche 901 1965-1968

Enhance your vintage Porsche’s performance with the Wavetrac Differential, specifically engineered for early 901 transmissions used in 1965–1968 911 models. This modern differential brings cutting-edge traction technology to classic cars, offering both improved handling and durability.

Built from scratch, the Wavetrac design features optimized gear tooth profiles for superior strength and better oil retention. Its compact gearset reduces rotating mass without compromising durability. Reinforced material in the side gear and axle interface ensures the unit holds up under high power loads — making it ideal for both stock and performance builds.

The key innovation is Wavetrac’s patented internal cam system, which activates under zero axle load to maintain drive to the wheel with grip — a major advantage over traditional torque-biasing differentials that effectively become open diffs in those conditions.

Manufactured in the USA by Autotech Driveline, each differential includes:

• 9310 alloy steel gears

• Case-hardened billet steel housings

• High-strength ARP fasteners

• A transferable Limited Lifetime Warranty

Ideal for early 911 owners who want modern traction and performance in a factory-compatible package.
