As long as you install them properly, high-quality 1 inch spacers are safe for cars, trucks, ATVs, and UTVs. But not all wheel spacers are created equal. If you want maximum safety and performance benefits from tire spacers, quality should be the top priority. Installing 1-inch wheel spacers is not a difficult task, but it requires some tools and skills.

You need to follow the instructions from the manufacturer and use a torque wrench to tighten the lug nuts to the specified torque values. Here is the REFERENCE torque spec on 1-inch wheel spacers:

  • M14 bolts or wheel nuts: 103.5 lb-ft (140 Nm).
  • M12 bolts or wheel nuts: 83.3 lb-ft (113 Nm).

For some wheels or applications, you may need more or less tightening torque. So, it’s best to consult a tire specialist to ensure the exact torque spec before operating.

Top 5 Factors to Choose the Best 1 Inch Spacers

  1. Quality Material
    Not all 1-inch wheel spacers are created equally. Always choose genuine brand wheel spacers that are made of forged 6061-T6 or 7075-T6 aluminum alloy.
  2. Precise Hub-centric
    For the best performance and safety, it is recommended to use hub-centric wheel spacers. Hub-centric spacers are better at keeping the wheel centered on the vehicle hub just like the OEM wheels.
  3. Wheel Stud Strength
    After installing, the 1 inch spacers become the important parts that connect the wheels and hub assembly. High-strength wheel lugs are necessary. Before shopping for wheel spacers, always check whether they are strong enough first.
  4. SGS TÜV Certification
    The SGS and TÜV offer a comprehensive range of specialist safety and quality tests. High-quality spacers should come with proper SGS TÜV performance test reports.
  5. Warranty
    Most genuine brand wheel spacers usually come with a warranty. The longer the warranty, the better.

Who Makes the Best 1 Inch Spacers for Sale?

Brand manufacturers focus on quality and performance. Before leaving the factory, BONOSS’s tech staff will do a series of inspections on the finished 1 inch spacers to check for any defects. They measure the individual aspects of the spacers to make sure that they meet the design specifications. BONOSS offers several key advantages that make their spacers a top choice.

1. Active Cooling for Better Braking

BONOSS forged active cooling 1 inch spacers come with petal-shaped grooves. The grooves allow the external cold air to flow continuously inside the spacer when it rotates. The air takes away the heat, actively dissipating heat for the braking system. This is good for performance brakes.

2. Precise Hub-centric for Zero Vibration

BONOSS forged active cooling 1-inch aluminum spacers are designed with better multi-stage hub-centric lips. The hub-centric metal ring is machined to be multi-layers, and the bevels fit the corresponding hub flange, which eliminates any kind of vibrations.

3. Full-cone Lug Seat for Improved Stability

What’s better, BONOSS forged 1 inch hub centric spacers come with full-cone lug seats. Full-cone seat design allows the studs and nuts to apply enough clamping force to lock the spacers, avoiding any potential loosening risks.

Frequently Asked FAQ

Q: Can you put spacers on spacers?
A: It is NOT recommended to put spacers on spacers. Using a single 2-inch wheel spacer instead of stacking 2 pcs of 1-inch spacers is the best way to ensure safety.

Q: How often should I torque 1 inch spacers on a truck?
A: It is crucial to re-torque your new wheel spacers after the first 50 to 100 driving miles. Then, just re-torque them every routine tire maintenance.

Q: Should I put anti-seize on 1-inch spacers?
A: It is optional to use anti-seize on wheel spacers. High-quality 1 inch spacers (like BONOSS spacers) won’t easily corrode or get stuck on your vehicle hub.
