This wheel centering sleeve set is for use on steer and drive wheels as well as most trailers. These sleeves stay on the wheel stud permanently and are used at the 12, 4 and 8 o’clock positions.

(Use three sleeves per wheel) We offer many sizes to fit most wheel configurations. Read the description and the product specifications below to see which sleeve meets your needs.
