3-40-1911 Spline Stub 1310-1410 Series 1.5" x 16 Splines fits 3.0" x .083 Tubing

Aftermarket spline stub like the 3-40-1911 fills the gap when factory driveline parts just don’t cut it — whether you’re repairing a worn PTO shaft, fabricating a custom driveline, or needing heavy-duty performance in agricultural or industrial gear. This aftermarket spline stub delivers precision fit and rugged durability, solving the weak-link issues many builders face.

This aftermarket spline stub brings serious specs: 1.5-inch major diameter with 16 splines, engineered to mate with 3.0-inch diameter tubing with a .083-inch wall thickness. That means a snug, secure fit that holds under high torque without the slop or vibration that kills components or loads.

With this part, you get more than just size matches — you get confidence. The spline stub is made from high-grade steel, precision‐machined, and finish coated so it resists corrosion and wear. It’s a dependable solution for agricultural, industrial, and automotive builds.

Features & Benefits

  • High Torque Strength – Handles demanding loads in automotive, industrial, and agricultural driven systems.

  • Precision Fit – 16 splines and exact dimensions ensure minimal backlash, smooth engagement, reduced wear.

  • Compatible with Common Tube Sizes – Fits 3.0″ OD tube with .083″ wall.

  • Corrosion & Wear Resistance – Hardened steel with treated finish for durability.

  • Reliable Warranty – Covered with a 1-year warranty.

Level Up Your Drive System

Say goodbye to weak joints, sloppy fits, and premature driveline failures. This aftermarket spline stub gives you a rock-solid connection so you can haul, tow, plow, or push with confidence.

Just installed the 3-40-1911 in my PTO drive on the farm unit in Des Moines — solid upgrade. Fit was perfect, no wobble even under full load. Feels built tough, worth every dollar.

Got this for my custom off-road build in Reno. Aftermarket spline stub is beefy, and welded nicely. No slop, no surprises. Looks like it’ll last through multiple seasons.
