  • What Is The Difference Between Aluminum And Steel?

The main difference between aluminum and steel is the weight difference which affects the rotating mass. Tensile strength for our billet 6061 t-6 aluminum is 45,000 PSI and for steel is 53,700 PSI. Our Billet Adapters are 2X thicker than steel, thus making them almost double on combined PSI. A 1.5" Aluminum Adapter weighs about 20 LBS, and a 1.5" Steel Adapter weighs close to 100 lbs. This extra rotating mass is unnecessary. Below is a side-by-side comparison of the 1.5" Aluminum and 0.75" Steel, which are the standard sizes we sell. The wheels you are going to be installing will most likely be made out of aluminum. In fact, Big Rigs that carry 70,000+ lbs. come with aluminum wheels. We sell both steel and aluminum adapters, and at the end of the day it's what makes you comfortable and works for your application.

  • Why Is The 1.5" Thick Adapters The Most Standard Size In Aluminum?

This 1.5" is the most standard because if we were to make them any smaller, you will either have to notch your wheel, and/or use the reverse studs method. Both methods are complex, so a 1.5" Thick adapters will avoid both issues. The bolt pattern is 225 MM and the wheel's hub bore is 220.1 MM. Anything smaller than 1.25" will not clear the wheel. 

  • What Is The Maximum Towing Capacity?

The maximum towing capacity we have tested on our adapters is 36,000 lbs. We tested this on a 2020 Ram 3500 Diesel which is rated to tow 32,000 lbs. with zero issues.
