IMPORTANT – Must check before purchasing
– SAFETY / INSTALL WARNING: Do NOT install wheel spacer if your wheel studs or lug nuts make contact with the back of your wheels.
– Wheel Stud Length: Your vehicle’s wheel studs need to be less than 2.0″ (50mm). If not, the back of your wheels need pockets long/wide enough for your studs.
– Fender Gap: Measure your wheel gap for clearance. You will need at least 2.0″ (50mm) of fender clearance to prevent the wheel/tire from hitting the fenderliner.
– If your vehicle hub is smaller than 125mm, we recommend purchasing hubcentric rings to reduce the chance of vibrations.
– If your vehicle doesn’t come with 9/16″ threaded studs, additional hardware will be required. Message us for help.
– No Returns or Exchanges once installed.
