BONOSS WHEEL SPACERS
AND WHEEL ADAPTERS

ALL ABOUT THE DIFFERENCE OF THEM

Wheel spacers and wheel adapters? You may think that they are identical
objects. As a matter of fact, they are two distinct things.

The Differences

Wheel Spacers vs. Adapters

  • Mostly, wheel spacers would only create the necessary distance on the inner portion of the wheel for clearance to solve the clearance problem of brakes, tie rods and other suspension components. If you plan to keep your current wheels and increase the offset of your car for enhancing the handling performance or exterior looks, then wheel spacers will be your ideal choice. The thickness is usually less than 4/5″. In summary, wheel spacers are only used to give a slight clearance for improving the overall handling and looks.
  • On the other hand, wheel adapters can not only do what spacers do but also can change the bolt pattern (and possibly center bore) to allow you to mount wheels that are not made for your car. If you intend to convert PCD/CB for fitting the wheels, then you should make a selection of wheel adapters. One of the common uses for wheel adapters is PCD conversion such as 5 lug to 6 lug adapters, 5×4.5″ to 5×5.5″ wheel adapters, 6 lug to 5 lug adapters. Two sets of bolts pattern hold the adapter in place. The adapters are usually made to offer space greater than 20mm (0.8 inches).

Super Fast

BONOSS design department and professional production line are able to complete your custom size wheel spacers in only 1-3 days.

BONOSS provide non-normal thickness’s customized service, 3mm-160mm thick, 130mm-350mm dimension is available, OEM/ODM is available. Before ordering, we need to know the thickness you want and the intended PCD conversion. Measuring the wheel gap is the most basic beginning of determining the thickness. Too thick, your tire may impact the fender. Do some measuring will help you find the proper thickness. What size of spacers do I need?

The other crucial thing is the bolt pattern. If you would like to convert the bolt pattern, then you need to figure out the bolt pattern of the wheels you attempt to add.
How to measure the bolt pattern?

How to measure BONOSS 4 lug wheel spacers bolt pattern

A 4 lug bolt pattern means that the wheel has 4 lug holes spaced evenly on a circle. Measure center to center of two holes directly across from each other.

How to measure BONOSS 5 lug wheel spacers bolt pattern

In a 5-lug wheel, measure from the back of a hole to the center of the second hole. The measurement method is a bit different from the 4 lug wheel’s.

How to measure BONOSS 6 lug wheel spacers bolt pattern

To measure a 6 bolt wheel, you need to measure center to center of two holes directly across from each other. It is the same as 4 lug bolt pattern.
