Alum Driveshaft 47in Long

The Precision Shaft Technologies Aluminum Driveshaft 47-inch (PST100470) is designed for high-performance vehicles and custom builds where weight reduction and rotational balance are essential. This driveshaft is particularly suited for mid-size to full-size platform applications, making it ideal for street performance builds, drag racing setups, and off-road vehicles.

Constructed from lightweight aluminum alloy, this driveshaft offers a significant weight savings compared to traditional steel alternatives while maintaining the necessary torsional rigidity for effective power transfer. Weighing 11.25 lbs, it effectively reduces rotational mass without compromising U-joint geometry or bearing preload characteristics. The precision engineering ensures proper driveline phasing, minimizing vibration issues that can arise from aftermarket installations.

This aluminum driveshaft is best suited for street rods, muscle cars, and late-model performance sedans, providing measurable gains in handling and throttle response. Precision Shaft Technologies designs each unit with tight tolerances to maintain OEM-level runout specifications, which is critical for eliminating driveline resonance across the RPM band.
