GLOCRORET 3/4"-36 Spline to 3/4" DD Steering Shaft U-Joint, 83mm Black, 4000 RPM, 35°

The GLOCRORET 3/4"-36 spline x 3/4" DD black single steering shaft universal u-joint is a heavy-duty, corrosion-resistant steering coupling designed to transmit torque smoothly at up to 4000 rpm and accommodate up to 35° of operating angle.

This single-joint steering shaft from GLOCRORET pairs a 3/4"-36 spline input with a 3/4" double-D (DD) output in a compact 83 mm (3-1/4") assembly finished in a protective black coating. Built from 40Cr alloy steel with precision needle roller bearings, it’s engineered for steering and light driveline tasks on street rods, sand rails, lifts, grinders and other automated equipment where a reliable, compact joint is needed.

How does this u-joint fit my steering system?

The joint mates a 3/4"-36 spline male shaft to a 3/4" double-D female receiver, so correct fit requires matching those dimensions. Measure the outer diameter of the round portion of your shaft and count spline teeth to confirm a 36-spline match.

• Input: 3/4"-36 spline interface for direct spline engagement.
• Output: 3/4" double-D (DD) flat-sided output for secure coupling.
• Total length: 83 mm (3-1/4"), compact for tight steering columns.
• Measurement tip: count spline teeth beginning at any tooth and include all around the circumference.

What performance limits and operating conditions should I expect?

This universal joint is rated for rotational speeds up to 4000 rpm and a maximum working angle of 35°. That makes it suitable for many steering and light power-transmission roles but not for high-speed drivetrain applications that exceed these limits.

• Maximum rotational/operating speed: 4000 rpm.
• Maximum working angle: 35° between connected shafts.
• Designed for intermittent and continuous steering loads at moderate speeds.
• Not intended for heavy-duty high-torque drivetrain use beyond specified ratings.

What materials and build quality features make this joint durable?

The GLOCRORET shaft uses 40Cr alloy steel and precision needle roller bearings for long wear life and consistent motion. A corrosion-resistant black coating protects the metal surface from moisture and environmental exposure.

• 40Cr alloy steel construction for strength and toughness.
• Premium needle roller bearings for smooth rotation and reduced play.
• Black protective coating to resist corrosion and surface wear.
• Compact design minimizes slack in steering linkages.

How do I maintain or replace this steering u-joint?

Routine inspection of the joint for looseness, binding, or visible corrosion will keep systems reliable. If play develops or bearings feel rough, replacement of the joint is recommended rather than attempting extensive field repairs.

• Inspect periodically for play and bearing noise under load.
• Keep connections clean and protected from debris and moisture.
• Replace if operating angle exceeds 35° or if speed/torque demands increase.
• GLOCRORET offers 12 months after-sales support for product issues.

Who is this for: This universal steering shaft is aimed at hobbyists and builders of street rods, sand rails, hot rods, custom steering columns, automated parking lifts and light industrial equipment that requires a compact, spline-to-DD coupling. Choose it if you need a precisely machined 3/4"-36 spline input, a 3/4" DD output, a short 83 mm profile, and durable alloy-steel construction rated for up to 4000 rpm and 35° of articulation.
