When fitting the 3R25-20, verify the 3R shaft stud measures 0.5" and the housing recess accepts the 1.24" seal OD. The product notes confirm this kit is the standard fitment across all 3R shaft configurations, making it the default choice for 3R CV ball replacement.

The 3R25-20 shares its 0.5" stud bore and 1.24" seal OD with the 2-9302 and 2-9301 kits, but those are listed as 3R series kits with a 0.91" ball diameter — confirming these serve different 3R CV configurations. The 3R25-20 is the broadly applicable 3R kit; verify the specific 3R shaft variant before ordering if the shaft has had any modifications.
