Alum Driveshaft 38in Long

The Alum Driveshaft 38in Long is a universal driveshaft engineered for light-duty to mid-range vehicle applications requiring reliable torque transmission between the transmission and rear axle assembly. This aluminum construction shaft is designed for operators seeking weight savings without sacrificing durability, making it ideal for off-road builds, restoration projects, and performance-oriented platforms where reducing rotating mass improves acceleration and fuel efficiency.

Built by Precision Shaft Technologies, this 38-inch driveshaft features aluminum construction that delivers significant weight reduction compared to steel alternatives while maintaining adequate strength for standard driving conditions. The shaft incorporates 1310-series universal joints at both ends, a proven standard that accommodates drivetrain angles and suspension articulation common in street and light off-road use. The 3-inch outer diameter profile provides the rigidity needed to handle consistent power delivery, and the natural aluminum finish resists corrosion while allowing for custom powder coating if desired. At 9.85 lbs, this shaft meaningfully reduces unsprung weight in the drivetrain—a critical factor for vehicles prioritizing efficiency and handling.

This universal driveshaft suits vehicle builders, restoration shops, and enthusiasts working on rear-wheel-drive platforms with standard flanged connections. The 1310 U-joint design ensures broad compatibility across common pickup trucks, muscle cars, hot rods, and custom builds. Installation requires proper alignment and balance; verify center bearing support and flange coupling sizes against your specific vehicle before ordering. For maximum service life, maintain driveshaft balance and inspect U-joints periodically during routine maintenance.
