Fitment of Drive Shaft Mounted Covers

Heavy truck drive lines are specified according to engine torque & intended use. Unlike autos, Year Make Model is irrelevant. To make part selection easy, Protector U-Joint Covers are separated into kits by driveshaft diameter, then U-Joint size (series).

Step 1.

Measure the drive shaft outside diameter (O.D.) with a diameter tape measure or deep jaw calipers. Drive shaft mounted cover kits are part numbered according to (a) Shaft Diameter (b) Standard or Large U-joints (DS or DL respectively). *Tip: you can also use a C-Clamp & measure between..

Example; 4625DSK fits a 4.625" (4-5/8") O.D. drive shaft with Standard U-Joints.

Step 2.

Determine the U-Joint size. Heavy duty U-Joints are separated into 2 size ranges; 1710 (approx. 6.4" to 6.9" u-joint cross) & 1810 (approx. 7.0" to 8.2" u-joint cross). The part number alpha suffix identifies the U-Joint series covered:

  • DSK = Drive shaft mounted, Standard U-Joint, Kit.

  • DLKDrive shaft mounted, Large U-Joint, Kit.

Ever heard someone say; "don't use greaseable u-joints, they break".. ? Most likely, the u-joints were 'clocked' incorrectly. Here's a visual guide to help.
