Check Your Vehicle Bolt Pattern/ PCD, Hub Bore Size, Thread Pitch, Vehicle fitment compatibility is only a guide.2. Measure the fender gap and stock bolt length to choose suitable thickness.3. PLEASE CONFIRM what you actuall need, wheel spacers or wheel adapters, they are different. Wheel Adapters are used to change bolt patterns in order to properly fit wheels from one vehicle to the hub of a different vehicle. 4. Do not use impact wrench.Please use hand wrench. Recommended to use threadlocker.5. Returns are only accepted if unused and not installed.(ReturnsARE NOT ACCEPTED IF SPACERS-ADAPTERS HAVE BEEN INSTALLED TO YOUR VEHICLE) What should I pay attention to during installation? 1) Check to make sure that the wheel spacer fits perfectly with the hub/axle stub and the inner mounting surface of the wheel.2) Make sure that the wheel bolts being used are of the appropriate length, not too long or too short.3) DO NOT proceed if both of the wheel spacer do not fit.4) Please be sure to clean the rust on the hub before starting the installation, otherwise it will affect the working life of the spacers.5) Make sure that you get 5-7 FULL TURNS of the lugs when installing. Torque them down to the manufacturers specs (up to and not greater than 110ft lbs).6) Avoid using an impact wrench because improper usage may cause the lug nuts/bolts to break or loosen while driving causing a potential injury or accident.7) All lug nuts, bolts and torque must be checked after driving the first 50 miles after installation. Afterwards, please check all lug nuts and bolts every 3,000-5,000 miles.8) Alignment is necessary after installation, this will prevent any wobble and vibration from occurring.
