TU395 – Tubing – Tube Dia 3.000″ – Tube Length 72″ – Tube Wall 0.095 DOM Tube

The TU395 driveshaft tube is the raw tube stock for custom or replacement driveshaft fabrication. It's steel DOM — 3.000" OD x 0.095"" wall — sold per foot and cut to your specification. The TU395 driveshaft tube is the starting material for a build; the yokes, u-joints, and balance work come after you've verified this tube diameter is correct for your application's torque load and critical speed.

Tu395 Driveshaft Tube — Steel DOM Specifications

The TU395 driveshaft tube specs: 3.000" OD x 0.095"" wall. SOLD AS A WHOLE STICK: Approx 72 inches long. Steel DOM (drawn over mandrel) — consistent wall thickness all the way through, no seam weld, no weak point. The correct material specification for driveshaft applications. Wall thickness determines torque capacity and critical speed rating. Thicker wall handles more torque but adds rotating weight — rotating weight matters more for RPM limits than static weight does, because it affects the critical speed calculation directly.

Before cutting the TU395 driveshaft tube to length, confirm the butt diameter of your weld yoke matches the tube OD. The yoke butt slides into or over the tube end — a loose fit here produces a concentric weld joint only if you're lucky. Measure both, cut clean, tack before full weld.
