Alum Driveshaft 38in Long

The Alum Driveshaft 38in Long from Precision Shaft Technologies is designed for builders and enthusiasts who require lightweight, high-strength driveline components. This aluminum construction driveshaft replaces heavier steel factory units, reducing unsprung weight and enhancing acceleration response without compromising torsional rigidity. Ideal for performance street machines, drag racing platforms, or custom hot rods, this driveshaft offers a balance of durability and weight savings that serious mechanics expect.

Manufactured from aerospace-grade aluminum, this driveshaft significantly reduces drivetrain rotational mass compared to traditional steel designs, resulting in quicker engine revving and improved weight distribution on the chassis. Weighing 9.85 pounds, it maintains critical stiffness while eliminating unnecessary bulk—a key advantage for tuning suspension geometry or maximizing acceleration.

The 38-inch length is suitable for mid-length applications commonly found in street rods, custom chassis builds, and performance modifications that require updating OEM driveshaft geometry or accommodating custom wheelbase changes. This Precision Shaft Technologies unit is perfect for builders working on independent rear suspension conversions, custom frame builds, or performance upgrades where both weight reduction and vibration damping are essential.
