New 3/4-36 Spline 3/4 DD U-Joint For Chevy Ford Universal Steering Shaft Coupler

3/4-36 Spline to 3/4 DD U-Joint for Chevy and Ford Universal Steering Shaft Coupler

This steering shaft U-joint couples a 3/4-36 spline input to a 3/4 inch double-D shaft, letting you connect a steering column to a steering box or rack on custom and retrofit builds for Chevy and Ford applications.

Overview

This universal steering shaft coupler joins a 3/4-36 spline shaft to a 3/4 inch DD shaft, making it a practical link for custom steering setups. The U-joint allows angular misalignment between the column and the steering gear, which helps on lifted, swapped, or fabricated vehicles. It suits builders working on Chevy and Ford projects who need a reliable spline-to-DD connection.

Built For Performance

• 3/4-36 spline bore on one end for a matched steering box or column shaft
• 3/4 inch double-D bore on the other end for DD steering shafting
• U-joint design accommodates angular offset between column and gear
• Steel construction suited to steering torque loads
• Universal fitment aimed at custom and retrofit steering assemblies

Fits These Machines

• for Chevy custom steering column and box builds with 3/4-36 spline
• for Ford custom steering column and box builds with 3/4-36 spline
• Universal applications pairing a 3/4-36 spline shaft with a 3/4 inch DD shaft

On-The-Job Use

• Connecting a steering column to a steering box on custom builds
• Linking steering components on lifted or modified trucks
• Engine swap and drivetrain retrofit steering assemblies
• Fabricated off-road and hot rod steering linkage

Specs At A Glance

Good To Know

Q: How do I confirm the spline end will fit my steering box? A: Count the spline teeth and measure the shaft diameter, then match them to the 3/4-36 spec before ordering. Spline counts and diameters vary, so verify against your exact component.

Q: Will this work with my existing DD steering shaft? A: It fits a 3/4 inch double-D shaft, so measure the flat-to-flat dimension and confirm the D profile matches. If the shaft is a different size or shape, a different coupler is needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
