The WK2 wheel spacers are wheel accessories for style and performance upgrades. By pushing the wheels and tires outward, they enlarge the track width. A wider track provides better handling and stability especially when cornering. The enhanced stability means better rollover resistance when driving in unfavorable conditions, reducing risks.
This also increase the inner wheel clearance which keep bigger brake calipers from rubbing against wheel spokes. High-quality WK2 wheel spacers are good to make your car look cooler and more aggressive. There are some factors to help you select the best wheel spacers and make them safe. In this article, our expert will explain the top 5 factors of selecting the safest WK2 wheel spacers.
Top 5 Factors of WK2 Wheel Spacers Fitment & Safety
Correct Sizes:
A vehicle-specific spacer is designed to fit your vehicle and only your vehicle. Specific wheel spacers for specific wheel hub. This provides a stable connection between the axle and the wheel. Precise bolt pattern (PCD) and center bore (CB) diameter are necessary. For example, Jeep Grand Cherokee WK2 (2010-2023): PCD=5x127mm, CB=71.6mm, Thread=M14x1.5mm.
Quality Material:
Forged aluminum WK2 wheel spacers are light in weight meanwhile strong, effortlessly withstanding heat and force, and are generally better in rust resistance. Poor-quality spacers may compromise safety. So, always choose genuine brand wheel spacers, which are crafted from forged 6061-T6 or 7075-T6 aluminum alloys.
Hub-centric Types:
Make sure they are hub-centric spacers instead of lug-centric spacers. Hub-centric wheel spacers can create a firm and stable wheel connection. This reducing the chance of wheel vibration. Thus, it is important to get hub-centric wheel spacers for the best handling and your own safety.
Wheel Studs:
For wheel spacer safety, the wheel studs must be strong enough to provide a proper clamping force. Higher-strength wheel studs provide a stronger load-bearing capacity. Experts recommend using WK2 wheel spacers with high-strength ISO grade 12.9 wheel studs.
SGS TÜV Certification:
The SGS and TÜV offer a comprehensive range of specialist safety and quality tests. High-quality WK2 wheel spacers should come with proper SGS TÜV performance test reports.
Why BONOSS WK2 Wheel Spacers Stands Out?
When selecting the best wheel spacers for Jeep Grand Cherokee WK2, BONOSS excels in safety and performance. With the advanced technology and unmatched quality, BONOSS offers several key advantages that make their spacers a top choice.
1. Useful Active Cooling Function
With the same price as most rim spacers, BONOSS forged active cooling WK2 wheel spacers provide an active cooling function. Distributed in petal shape, these grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates.
The air takes away the heat to actively dissipate heat for the brakes. Such BONOSS forged active cooling WK2 spacers improve the cooling efficiency, reducing brake thermal decay, and improving road safety.
2. Aerospace-grade Aluminum Materials
All BONOSS forged active cooling WK2 wheel spacers are made of forged 6061-T6 or 7075-T6 billet aluminum alloy. The tensile strength is up to 572 MPa and the yield strength is up to 503 MPa (as strong as aviation aircraft). High tensile strength gives it strong resistance to being pulled apart, making it resistant to bending and breaking.
3. High-strength Fasteners for Improved Safety
Make sure the provided wheel studs are strong enough. BONOSS forged active cooling WK2 wheel spacers come with ISO grade 12.9 wheel studs. These wheel studs are approved by SGS and TÜV: tensile strength≥1,220 MPa, proof load≥121,000 N. Arguably, a stronger retention power on the wheel is necessary to properly secure the spacer and wheel in place.
Final Verdict: Upgrade Your Car with BONOSS
From innovative active cooling benefits to certified materials and precise manufacturing, BONOSS forged active cooling WK2 wheel spacers are engineered to enhance your driving experience with safety, strength, and reliability. Discover the difference with BONOSS—built for drivers who demand excellence.
