Q & A

What's in the Box

Dont 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 are CNC machined from aircraft steel to precision tolerances. The sealed needle bearing design will last ten times longer than a standard pin and block universal joint. The unique nickel plating prevents rust without the hassle of painting.

  • 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.

Item Details

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

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.

Will this tilt column fit a 1973 Javelin, with floor shift?

The p/n 91032401 referenced in your request is a steering u-joint use for mating a 1"DD Ididit column to a 3/4" DD shaft and not a tilt steering column. Assuming your request is in regards to an Ididit tilt column, the answer is yes, if your willing to wire to a 69-94 GM column wire harness. Almost all aftermarket full columns are patterned after the 69-94 GM in style and wiring.

Sorry the picture is not of this particular 3/4" DD X 1" DD joint, it's a generic picture of some other combination. This joint will have a set screw on both ends so that it can be installed without welding. All of our DD U joints and splined U joints have set screws for that reason. The round (or smooth bore) U-joints are intended to be welded on so they do not have set screws.

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.
