JConcepts 11mm Offset 12mm Aluminum Hex Adaptors are a machined aluminum option for JConcepts Tribute wheels. These are a great upgrade for high-power monster trucks, and allow racers to power up and race worry free. The precision machined hexes are light weight, feature black anodizing with laser engraved offset markings. The hex adaptors bolt-up with existing hardware from the #3377 wheels in a 6-lug pattern and include flanged nylon insert lock nuts for bolt-on security.
