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.

Overall Assessment

Customers appreciate our product for its small size which provides necessary clearance for header applications. The product stands out for its excellent build quality, ease of installation and great fit. Despite facing issues with compatibility in specific scenarios, such as Flaming River Steering Column, customers laud the fact that it performs on par, if not better, than more expensive alternatives in the market. This affirms that our product not only fulfills its purpose effectively but also delivers superior value for money.

The 1" -48 spline end does not fit a Flaming River Steering Column (FR30002BK) shaft that is advertised by Flaming River as having a 1"-48 SHAFT. The U-Joint is too small. Not sure if this is an error on Flaming River or U-joint maker. The FR Steering column was for 68-72 GM A body. Device does look to be good quality though.
