Q & A

What's in the Box

Don't jeopardize your safety with inferior quality steering components. Speedway offers only the finest steering U-joints available. Made by Sweet Manufacturing. These steering universal joints have a 3/4" round weld-on end.

  • Full compliment bearings
  • Forged Vanadium steel yokes and u-joint
  • Highest quality for racing or street
  • Features needle bearing u-joints
Learn more about u-joints and steering systems by reading our tech article. U-Joint Selection and Design.

Note: GM columns measure slightly less than 1" while IDIDIT and Flaming River columns measure a true 1".  DO NOT interchange these u-joints.

Application

When purchasing U-Joints, 3 easy steps will help ensure that they will be correct for your application.

STEP 1
Be sure to measure the diameter of the shaft and count the number of splines on the shaft. Some shafts have a blank spot ground on one side. To get the correct number of splines, use a flat edge and cover the blank half of the shaft through the diameter and count the splines on the other half. Multiply that number by 2, thus giving you the total number of splines on the full circumference of the shaft.

STEP 2

Choose which shaft type best suits your application: 3/4" weld on, 3/4" DD or 1" DD.

STEP 3
With these two pieces of information at hand, refer to our chart to find the appropriate part number of the ujoint for your specific application.

Notes

Tech Tip #1: When using more than two universal joints in a system, a support heim must be used.

Tech Tip #2: Increasing a U-Joint's angle of operation beyond 30° dramatically increases the stress on the joint, weakening the whole steering mechanism. If a greater angle is needed, add another u-joint.

The 1” double D end fits the bottom of most of the Ididit steering columns. The opposite end of the u-joint fits a piece of ¾” diameter round shaft. The end going to the ¾” round shaft is typically welded to the shaft or cross-drilled and pinned with a couple of roll pins.

GM columns measure slightly less than 1" while Ididit and Flaming River columns measure a true 1".

These polished stainless steel U-joints look great and use a pinch bolt on each end for easy installation.

This is a size that is used on some large GM steering columns. This specific steering universal joint uses a pinch bolt fastener on the 3/4"DD side and a set screw on the 1"DD side, due to the large size

NOTE:  These u-joints contain a safety feature that requires the DD steering shaft to be notched for pinch bolt clearance. Once notched, the pinch bolt MUST be torqued to 45 ft/lbs to ensure a tight fit.
