For you scale heads looking to do a work truck project, this is an Adjustable Hardened Steel Dually Adapter for 5 Lug Beadlock Wheel. Use true beadlock wheels for dually setup instead of glued on wheels that don't work well.
This adapter allows you to adjust the width in between the tires from 8.5mm to 14.5mm, meaning you can choose different tire widths. Any tires between this width range (24mm/0.94" to 33mm/1.3") will work and leave just the right amount of gap in between the tires.
Using the tires we recommend here below, you will be able to see a gap in between the dually tires for realism.
We recommend these tires: 1.55" SP Road Tracker #BRTR15501 1.55" Baby Hustler #BRTR15502
