3 fits very well, 1 needs to tighten the nuts for a tighter fit. Manufactured from thicker metal (SS) than most 2006 International 7600 "Chrome" caps with a Meritor/Rockwell rear differential.
Looks good and fits my RV when the tire salesman couldn't find one. Secure. I've just come back from 3500 miles on some pretty horrible roads and all four are still there. Thank you Great General!
They had thin lugs so they wouldn't work without repositioning the axle nuts but would fit snugly on some other drive axles with flat type axle nuts. Eaton rear wheels require a thicker lip or axle nuts with turned-out corners.
