MANUFACTURING & DESIGN

Raw Materials
Constructed using aerospace grade aluminum, our raw materials are carefully curated and all of which undergoes a stringent inbound quality control process.
 

Perfectly Hubcentric
Designed to fit perfectly over your wheel hub, virtually eliminating the possibility of high speed vibrations. Wheel spacers also feature a hubcentric lip to help your wheel center properly.
 

CNC Machined
Our manufacturing facility utilizes the newest, state-of-the-art machinery. Spacers are crafted to exacting specifications and meticulously checked prior to leaving the facility.
 




 



 

Universal VS Hubcentric with Lip

Hubcentric spacers are designed to fit snugly over your vehicle's center hub, allowing your wheel/tire to center properly, preventing vibrations and premature wear of wheel/tire components. This also gives improved safety over universal spacers by reducing the chance of lug nut/bolts sheering off during events such as driving through a deep pothole or wheels making a hard impact against objects such as curbs and other road hazards.
Non-hubcentric Spacer
Will not properly center around your vehicle's hub. This causes it to rotate unevenly during driving, which is one of the main causes for steering wheel vibrations
Hubcentric Spacer with Lip
The 70.5mm centerbore of these spacers will properly center around your vehicle's hub.  In addition, the 70.5mm diameter lip allows you to center your wheel.

Important Notes




 Important Safety Advisory
As with any component you purchase for your vehicle, installation should be done by a qualified technician. We've provided the following information as a general reference for purchasing and installing these spacers/adapters. The following list isn't all-inclusive and may be different depending on the vehicle you drive, type of wheels you have, and ideal setup you're trying to achieve. Failure to install properly may cause your lug nuts/wheel studs/spacers to loosen or break while driving. If you are not confident or familiar with the installation, please ask a trained professional for help.

Before Purchasing
- Measure your wheel gap for clearance. You will need at least 3/4" (20mm) of clearance to prevent the wheel/tire from hitting the fender or fenderliner.
- The vehicle’s wheel studs need to be measured. If the studs are longer than 3/4" (20mm), it will extend past the spacer's surface.  It may not be possible to bolt the wheel safely onto the spacer, depending on whether your wheels have pockets/cavities around the mounting pad.
- If your vehicle does not have 12x1.5 threaded wheel studs, you would need to purchase the correct threaded lug nuts for proper installation.

WARNING: The included lug nuts extend past the face of the spacers. IT IS REQUIRED that the back of your wheels have small cavities (at least 2" width and 1/4" deep) in the mounting pad for installation of these spacers. These cavities are NEEDED so that the lug nuts and wheel studs can sit in this pocket.  Verify this before purchasing.



Before Installation
Check compatibility of spacer-to-hub, spacer-to-wheel, and lug nuts (thread pitch & seat type)

During Installation
- Installation should be performed by a trained professional using proper tools.
- Avoid using an impact wrench or any pneumatic tools; improper usage may cause damage to components.
- Ensure proper thread engagement. Typically, its a minimum of 5-8 turns before the lug nut tightens, however, it varies depending on thread pitch and type of vehicle.
- ALL Lug Nuts (on the spacers and the wheels) MUST be torqued to manufacture specifications.

After Installation
- Test drive your vehicle to ensure the hardware is installed properly. Pay close attention for any noises, vibrations, or compatibility issues (such as fender rubbing).
- Inspect and re-torque ALL lug nuts after 25-50 miles of driving. This requires you to take off the wheels to tighten the lug nuts holding the spacers to your vehicle.


Note: No returns or exchanges once product has been installed on the vehicle.
