- Bed load hauling - Adapter dually wheels increase stability. If you are hauling a big load in the pickup box and wondering every time the weight shifts whether that single tire might blow out, then you need the greater stability of dually wheels.
- Campers - In addition, pickup campers are often top-heavy. If you want to use your pickup camper regularly and do so in comfort, then a set of dually wheels is the right choice for you. It is the optimum way to haul any load. It makes a world of difference when you are behind the wheel.
- Trailers - Dually adapters allow the pickup to pull heavy trailers. Crosswinds and semi winds make pulling a trailer tough. Pulling a heavy trailer is easier with the stability of dually wheels.
rim adapters extend the wheel enough to create a wider area to accept a second tire rim and wheel. Take a moment and study a dually wheel hub. A dually axle extends out several inches from the rotor to accommodate a second tire and wheel. Single mount wheel hubs extend out from the rotor only a fraction of an inch. An adapter supplies the same extension found on factory dually hubs. Most pickup trucks are going to require 8 lug wheel adapters for conversion.
The process of using wheel adapters to convert a single to a dually for an eight-lug pickup truck wheel is easy to understand.
1. Research your wheel hub and find an adapter with eight holes. Order the appropriate adapter. Also consider the construction of the wheel adapter. If you’re going to be carrying heavy loads, the wheel adapter will be stressed. Look for extruded billet material that’s designed to support hefty loads.
2. Jack up the truck as if to change the tire. Remove the single wheel and expose the wheel hub.
3. Be certain the studs are flush on the wheel hub surface.
4. Place the adapter over the studs so that the end of the stud is slightly inside the holes on the adapter ring. The idea is to provide the adapter with a completely flat surface. Tighten the adapter with lug nuts provided with the adapter. A conventional socket may not tighten the lug nuts in many adapters. You are recommended to use a thin walled long socket of either 3/4" or 13/16" hex, and apply with a torque wrench, tightening the adapter down to the torque designated by the instructions. Your inside dually wheel will now work fine with the adapter in place.
5. Pick out a set of dually wheel rims that match the stud hole number. Go for six-inch rims. For tires, use the same height tire you removed from the truck.
6. With the new adapter ready to take the wheels, put the rims and tires on, one at a time. Tighten down the lugs on the new adapter studs. With the two wheels on tight, you are ready to repeat the process on the other side.
7. It is important to break the adapter and rims in. The lug nuts can come loose in the first few miles. After driving the initial mile, get out and check the lug nuts. Do not take any long trips until you are confident the lug nuts are holding.
8. You must encase wheels in fenders. Your pickup’s conventional fender doesn’t accommodate two wheels, so you can either add aftermarket fenders, buy a new dually pickup bed or find a dually bed for your truck in a scrap yard.
