3 fit very well, 1 need 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 great and fits my motorhome when the tire shop couldn't find the right ones. 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 a thin lip so they didn't work without repositioning the axle nuts but did fit quite a few other drive axles with flat type axle nuts. Eaton rear wheels require a thicker lip or axle nuts with turned-out corners.
