Utility Vehicle Wheel Spacers are made in a variety of patterns and widths. Here is a pair made in a 5" width. See the next photo down for what they would look like in a 3" width.

Each spacer is custom made from 1/4" plate steel and welded fabrication. The photo shows 3" wide spacers (but they can also be made in other wider widths if you prefer). $215/pair (add $12.50/half inch for widths over 2.5") (includes a set of lug bolts) plus $15 US shipping, $50 to Canada.

4 Bolt Front Spacers for the Kubota BX Series are custom designed with 9/16" threading and the proper 60 degree taper that matches the OEM lugs and are priced at $190 per pair.

Also available is a variant of this same pattern that fits the Kubota BX 1500 and 1800 models that have an even smaller diameter front rim and tire than the rest of the BX Series. The bolt pattern and lug bolts are identical but both the inside and outside diameters of the spacers are just a bit smaller to fit into the unique curvature of the front rim. Same Pricing.
