Generally, there are two types of half inch wheel spacers: universal spacers and vehicle-specific spacers. Generally, vehicle-specific spacers are considered safer and more reliable than those universal types. They are machined to your vehicle specification, which ensures perfect fitment. A vehicle-specific spacer is often hub-centric.
Hub-centric half inch wheel spacers are machined to fit the specific vehicle hub, reducing wheel vibration issues. On the other hand, universal wheel spacers come with larger hub bore diameters so that the spacer can fit a wider array of vehicles. It is not a good idea to use universal half inch wheel spacers.
How Many mm is a Half Inch Wheel Spacer?
A half inch spacer is approximately 13mm. A 1/2-inch spacer moves the wheel about 13mm outward, effectively reducing wheel offset. Giving an example, if you get a +45mm offset rim, then 1/2-inch wheel spacers change the offset to be 32mm (45mm–13mm=32mm). This gives your vehicle a wider wheel stance.
Top Picks of Half Inch Wheel Spacers
In the market, the wheel spacers may look the same, but not all 1/2” wheel spacers are created equal. There are several key factors to use half inch spacers safely.
1. Bolt Pattern (PCD):
To ensure a safe fit, the spacer bolt pattern must be the same as the vehicle lug pattern. Double-check the vehicle bolt pattern in your owner’s manual before buying a set.
2. Torque Specs:
The REFERENCE torque spec for half inch wheel spacers can be 83.3 ft-lbs for M12 bolts and 103.5 ft-lbs for M14 bolts. Remember that this is just a reference to the possible torque. It is always recommended to ask a tire professional for help.
3. Quality Material:
The best half inch spacers are made of high-strength materials like forged 7075-T6 aluminum alloys. These materials offer superior strength and resistance to the harsh conditions encountered during passionate driving.
4. Extended Wheel Bolts:
High-strength extended wheel bolts are necessary if you add 1/2-inch wheel spacers. For example, if the OEM bolt length is 30mm, then you need 43mm wheel bolts to safely secure a half inch wheel spacer.
5. Hub-centric Design:
Hub-centric spacers can create a firm and stable wheel connection. If you often take your car to the track or off-roading adventures, you will eventually need wheel spacers with integrated hub-centric rings to ensure safety.
Who Makes the Best Half Inch Wheel Spacers?
Brand manufacturers focus on quality and performance. Before leaving the factory, BONOSS’s tech staff will do a series of inspections on the finished 1/2-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. Lightweight for Better Performance
These BONOSS forged lightweight plus 1/2-inch wheel spacers are machined with “Hollow Carved” holes. Due to these hollow holes, the average weight of each spacer is over 20% lighter than the previous-gen product. Adding such a small, lightweight component won’t affect the speed or hurt the suspension parts.
2. Precise Hub-centric for Zero Vibration
BONOSS forged lightweight plus half 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. ISO Grade 12.9 Bolts for Improved Stability
High-strength wheel bolts ensure a strong wheel-spacer-hub connection. BONOSS provides ISO grade 12.9 wheel bolts for safely securing your 1/2” spacers. These wheel bolts are made of high-strength forged SCM440 alloy steel. They perform well in many tests: tensile strength≥1,282 MPa, ultimate tensile load≥152,000 N, and NSS≥192H.
Final Summary: Elevate Your Wheel Style with BONOSS
With attention to innovative engineering and a relentless pursuit of quality manufacturing, BONOSS forged half inch wheel spacers surely give you the perfect wheel style and fitment along with confidence for years of rugged use. Choose BONOSS and experience the difference—engineered for those who demand the best.
