      FREQUENTLY ASKED QUESTIONS
      • 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 size became popular because it cleared tires that are 13.5" wide up front and will give you a better stance on your truck. We can also make them as narrow as 1 inch for this specific size.

      • 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.

      • Will These Work On Single Rear Wheel Trucks?

      Front Wheels: For the front, you will need a factory hub extension which is about 3" long in order to properly sit any dually wheel. Then you can install this 8 to 10 lug wheel adapters. If you don't have that factory hub extension, or cannot source one we can make you a 3" wheel adapter for the front. This will compensate for the hub extension.

      Rear Wheels: For the rear, the 1.5" thick will have enough clearance to mount dually wheels and clear the leaf springs.

      • My Stud Got Damaged, Can I Buy Replacement Studs?

      If for any reason you need to get replacement studs, we also carry them. Please look at the Lug Nuts & Spacers tab for more info.
