US Wheel Adapters

A guide to wheel adapters, wheel spacers, and hub centric rings


What are wheel adapters?Us Wheel Adapters

Wheel adapters are used when installing a wheel  that has a different bolt pattern than the vehicle.  Adapters are commonly used to change the bolt pattern in order to properly fit wheels from one vehicle to the hub of a different vehicle.  eg  “6×5″ to 6×5.5″”  or  “14×1.5 Studs to 9/16 Studs”.  They can also be used to properly fit aftermarket wheels.  Wheel adapters are available in hub/lug centric designs. (bolt-on/slip-on)

What are wheel spacers?

Wheel spacers widen the stance of a vehicle using the factory wheels.  Wheel spacers will keep the same bolt pattern as the vehicle.  Spacers are available in two main designs, hub centric and lug centric. US Wheel Adapters manufactures bolt-on and slip-on style wheel spacers.  Slip on style spacers slide over the existing studs, so it is important to make sure that there will be enough thread left past the wheel spacer to securely install the wheel.  Bolt on wheel spacers bolt to the hub of the vehicle using the factory studs and provided lug nuts.  You can then secure the wheels to the studs of the wheel spacers using the factory lug nuts already on hand.

Do I need slip on spacers or bolt on?

Slip on*

US Wheel Adapters manufactures slip on spacers for cars, trucks, and SUVs. These  style spacers are generally lower priced due to a lesser amount of material being needed.  Slip on spacers are bought when a user needs more clearance from the hub of their vehicle usually due to brake calipers being too close.  Using slip on style means that a portion of your wheel studs will be covered by the spacer. Thus it is important to make sure there is enough thread left past the spacer to properly secure the wheel.  Otherwise extended wheel studs will need to be installed as well.

Bolt on*

Bolt on wheel spacers and adapters are available in hub and lug centric style. They will bolt onto the existing bolt pattern of the vehicle and mimic this pattern on the face side of the spacer.  This style wheel spacer or adapter comes in a minimum of 1″ thick to allow for a flush fit with wheel studs.  This means a flush fit is necessary so the wheel studs don’t prevent the wheels from sitting flat against the face of the spacer or adapter.  Bolt on spacers offer a more secure way of spacing your wheels for aesthetic or track widing purposes. This is the prefered style for off-road use and Truck/SUV applications.  However, bolt on wheel spacers are necessary if wanting to safely space wheels further than 3/4″ away from the hub.

Hub Centric vs Lug Centric.

The terms Hub centric and Lug Centric refer to the way in which wheel adapters or wheel spacers center onto the vehicle.  Lug centered wheel spacers and adapters are usually less expensive then their hub centric counterparts.  These designs use less material during the machining.  Lug Centric wheel spacers/wheel adapters are fine when installed and maintained correctly.  However these style products can cause vibration issues when under heavy haul load, or used for extended highway driving.  For this reason the hub centric design is suggested and prefered for long or heavy hauling,  highway use, and performance applications.  While we have a wide selection of lug centric designs, most of our hub centric designs are going to be a high quality custom build.    

What are Hub Centric Rings?

A hub centric ring is a plastic or aluminum ring used to resolve vibration issues caused by a difference in size between the Hub Diameter of the vehicle and the Center Bore of the Wheel. You would need a set of hub centric rings if your aftermarket wheels contain a center bore larger than your vehicle.  Aftermarket wheels will cause vibration issues if no hub ring is used.  Hub centric rings can also be used to bring the center bore size up to the center bore of another factory wheel.  Hub rings can be used in combination with hub centric adapters and wheel spacers if the center bore is not large enough for your application.  We at US Wheel Adapters stock Pre-built common sizes.  We also build custom hub rings using all American Material and machines.
