These wheel adapters are designed to convert your truck's 8x210 mm bolt pattern to the medium-duty 8x275 mm bolt pattern. Common 8x275 wheels include 19.5" and 22.5" options from Kodiak, Top Kick, GM Silverado 4500/5500, International 4300, Freightliner M2, and certain Ford F-650 trucks, as well as aftermarket wheels with the same bolt pattern.
Important Note These adapters have M22x1.5 studs. If your wheels need M20x1.5 due to smaller holes, you may need to enlarge them. Most wheels fit M22x1.5, but we can accommodate M20x1.5 with limited stud length.

Frequently Asked Questions
What Is the Difference Between Aluminum and Steel?
Steel is prone to corrosion, while aluminum resists it. The key difference between the two is weight, which significantly impacts rotating mass. Here's a detailed comparison:
-
Tensile Strength:
- Billet 6061 T-6 Aluminum:45,000 PSI
- Steel: 53,700 PSI
- Thickness: Our aluminum adapters are twice as thick as steel, offering nearly double the combined PSI.
-
Weight:
- 1.5" Aluminum Adapter: 25 lbs
- 1.5" Steel Adapter: 48 lbs
Why Are 1.5" Aluminum Adapters the Most Popular Size?
The 1.5" thickness is widely preferred because it provides clearance for tires up to 13.5" wide in the front and improves the truck's stance.
What Is the Maximum Towing Capacity?
Our adapters have been tested to tow up to 36,000 lbs. This was successfully demonstrated using a 2022 Ford F-550 without any issues.
