1. Zoffado 8×6.5 to 8×170 Wheel Adapters: Best Overall
In our evaluation, the Zoffado adapters stand out due to their use of 7075-T6 aluminum, which offers a higher tensile strength than the more common 6061 alloy found in many competitor models. We compared the spec sheets and found the heat treated studs meet or exceed OEM standards, providing crucial peace of mind for heavy truck applications. Based on owner feedback, these adapters maintain structural integrity even when subjected to significant towing stress and off road impacts.
However, buyers should be aware that the premium materials come with a higher price point. We determined that if you are using your vehicle for light duty or strictly highway driving, you might not strictly need the enhanced strength of 7075 aluminum. Budget conscious shoppers who do not push their vehicle to the limit might find a more affordable option sufficient.

We researched their manufacturing process and confirmed they utilize solid 6061-T6 aluminum blocks, which provides a good balance of ductility and strength. Owner feedback highlights the hub centric design as a major benefit, noting a significant reduction in highway vibrations compared to cheaper lug centric alternatives.
One limitation we observed involves the included lug nuts. Some owners report that the thin wall design of the lug nuts requires a specific socket that may not be in every standard tool kit. We recommend skipping this set if you do not want to buy specialty tools, or if you prefer a different style of lug nut for ease of maintenance.
- ISO 9001 certified manufacturing
- True hub centric design reduces vibration
- Includes open ended lug nuts
Pros: Excellent fitment accuracy reduces wheel wobble; High quality anodizing prevents rust
Cons: Lug nuts can be difficult to torque with standard sockets
3. Wheel Adapter USA 8×6.5 to 8×170: Best for Custom Builds
We found that Wheel Adapter USA offers a distinct advantage for builders who prioritize domestic manufacturing and quality control. Our research indicates they use high grade 6061-T6 aluminum sourced from US suppliers. The machining quality is evident when comparing the surface finish and stud alignment to imported alternatives, making them a reliable choice for custom restorations or unique fitments.
The main drawback we identified is the availability. Unlike mass produced brands found on Amazon with Prime shipping, these adapters are often made to order. Based on our evaluation of shipping times, you should skip this option if you need adapters immediately for a time sensitive repair or installation project.
- Manufactured in the United States
- Customizable thickness options available
- High precision CNC machining
Pros: Superior build quality and material traceability; Excellent customer service for fitment questions

Frequently Asked Questions
Are 8×6.5 to 8×170 adapters safe to use?
Yes, they are safe when manufactured from high quality materials like 6061-T6 or 7075-T6 aluminum and installed correctly. We researched safety standards and found that hub centric designs which center on the axle hub rather than the lug nuts are significantly safer. You must also ensure the studs are torqued to the manufacturer specifications and re checked after a short drive.
What is the difference between hub centric and lug centric adapters?
Hub centric adapters have a lip that fits perfectly over the vehicle’s hub, centering the wheel and reducing vibration. Lug centric adapters rely on the lug nuts to center the wheel, which can lead to vibration at high speeds. In our evaluation, hub centric adapters are preferred for heavier trucks and SUVs to ensure stability and safety.
Do I need longer lug nuts for these adapters?
Most adapters come with their own studs pressed into the spacer, so you use the lug nuts provided or your wheel’s lug nuts to secure the wheel to the adapter. However, you still need your original lug nuts to secure the adapter to your vehicle hub. We compared included contents and found most top brands provide the necessary hardware for the wheel side.
Will these adapters push my wheels out?
Yes, wheel adapters add thickness which pushes the wheel outward from the hub. This is necessary to clear brake calipers or suspension components and to achieve the correct bolt pattern. We compared various thicknesses and recommend checking your local laws regarding how far the wheels can protrude past the fenders.
How often should I retorque the adapter nuts?
It is critical to retorque the nuts holding the adapter to the hub after the first 50 to 100 miles of driving. Based on our research of mechanical standards, new studs can settle and loosen slightly initially. After the initial retorque, regular checks during routine maintenance are recommended to ensure safety.
Our Verdict
Based on our research and comparison of specs and owner feedback, the Zoffado 8×6.5 to 8×170 Wheel Adapters are the top pick for their superior 7075-T6 material strength and safety. The Orion Motor Tech 8×6.5 to 8×170 adapters are the runner up, offering excellent value and precision for most daily driving needs.
