From Gear Head RC:
Gear Head RC is proud to introduce the new 2.2 M-220 EZ-Loc aluminum beadlock wheel. Made in the U.S.A. from CNC-machined 6061-T6 aluminum, this new wheel adds a unique scale look to your 2.2 rock crawler, rock racer or desert race truck.
The EZ-Loc beadlock design makes mounting even the most difficult tires a breeze. The 2.2 M-220 EZ-Loc wheel is also reversible, so you have two offset options with the included hubs. Other offsets are available by using optional plus .250″, plus .375″ and plus .500″ hubs (sold separately).
Each set of wheels includes (4) billet aluminum wheels, (4) aluminum hubs, (8) aluminum EZ-Loc beadlock rings and #4-40 screws.
Wheels come in sets of four or as spares. Here are their specs:

Width: 1.54″ (39.4mm)
Offset: -.085″ OR -.275″ (-2.2mm OR -7.0mm)
Weight (each wheel): 5.3 oz. (151g)
