3326-306A – Weld Yokes – 1330 Series – Butt Dia 2.757″ – Tube Dia Wall 3.000X0.125

Building or rebuilding a 1330 series driveshaft means getting the weld yoke right first. The 3326-306A weld yoke is machined for one tube diameter and one series — those two specs are non-negotiable. Get the butt diameter wrong and the weld joint is already compromised before you strike the arc.

3326-306A Weld Yoke — Tube Fit & Aluminum Specs

The 1330 series covers light-to-medium duty trucks and GM half-ton platforms. The 3326-306A weld yoke specs: fits 3.000X0.125 tube | 2.757" butt dia | 2.500"" center-to-weld. Aluminum T6061 — roughly 60% lighter than steel equivalent, corrosion resistant, correct for high-RPM builds where rotating mass matters. Center-to-weld dimension is critical for total shaft length calculations — it's the distance consumed by this yoke on that end of the tube.

Measure your tube OD before cutting and welding the 3326-306A weld yoke. Tack it in place first, check runout is within 0.005" before committing to full weld. A slight off-angle tack that gets welded solid will show up as vibration at 50+ mph that no balancer can fully correct.

Key Features

• Series: 1330 — light-to-medium duty trucks and GM half-ton platforms
• Tube fit: 3.000X0.125 — butt diameter is machined specifically for this OD
