Steel Driveshaft 55in Long 3in Dia.

The Steel Driveshaft 55in Long 3in Dia. is a heavy-duty transmission shaft designed for custom automotive builds, restorations, and high-performance vehicle modifications where OEM driveshafts require replacement or lengthening. This component transfers rotational power from the transmission to the rear differential, making it critical for any vehicle experiencing driveline work.

Constructed from high-strength steel tubing, this 55-inch driveshaft with a 3-inch diameter provides the structural rigidity needed to handle torque loads without deflection or premature failure. The steel construction ensures durability in demanding applications where aluminum alternatives may flex under sustained acceleration or towing loads. At 20.3 pounds, the shaft strikes a balance between weight and strength, making it suitable for street, strip, and off-road environments.

This driveshaft is ideal for mechanics and fabricators working on vehicles with modified frame lengths, extended suspensions, or non-standard drivetrain configurations. The 55-inch length suits mid-size platform vehicles, particularly those requiring custom driveline kits. Its compatibility with standard U-joint yokes makes it a versatile choice for various applications.
