Steel Driveshaft 46in Long 2.5in Dia.

The Steel Driveshaft 46in Long 2.5in Dia. from Precision Shaft Technologies is a heavy-duty drivetrain component designed for custom vehicle builds, high-performance modifications, and specialty automotive applications. This solid steel driveshaft serves as the critical rotating link between your transmission output and rear differential, transferring engine torque while maintaining rotational balance under load.

Built from solid steel construction, this 2.5-inch diameter shaft delivers the strength needed to handle significant torque loads without flex or runout. The 46-inch length makes it suitable for mid-wheelbase applications, custom frame rails, and non-standard drivetrain layouts where factory-length shafts won't fit. Precision Shaft Technologies manufactures this component to exacting concentricity standards, reducing vibration and extending differential bearing life by ensuring minimal runout during rotation.

Mechanics and fabricators working on tube-frame racers, vintage restorations, and adaptive drivetrains will find this driveshaft ideal for one-off configurations where a properly sized driveshaft is essential for safe power delivery and drivetrain longevity. The weight of the driveshaft, at approximately 14.45 lbs, contributes to overall vehicle mass and rotational inertia calculations, which are critical factors when tuning suspension geometry or planning weight distribution.
