  • 1st. Select Mounting position which is designated by the 1st letter in the 3 letter alpha-suffix:

For driveshaft mounted covers you'll need to measure your driveshaft tube diameter and select the corresponding part number. Next, you'll need to know the approximate u-joint cross diameter, Under 7" or Over 7"

Example: 4625DSK fits a 4-5/8" driveshaft tube with "Standard" u-joints (under 7") such as SPL250

Example: 4625DLK fits a 4-5/8" driveshaft tube with "Large" u-joints (over 7") such as 1810

​​

 

 

Slip-Yoke and Yoke Shaft mounted covers are "Multi-Fit" so there's no need to measure the shaft diameter, just determine the u-joint / yoke cross diameter, Under 7" or Over 7".

  • 2nd. Select U-Joint size which is is designated by the 2nd letter in the alpha-suffix.
