    Venomous Style. Add some wild, inspired style to your Silverado with the Mamba Black 6-Lug Wheel measuring 20x9. Featuring 8 uniquely shaped, flared spokes with machined beadlock accents and inner silver accent lining, this wheel emanates the Black Mamba snake's own aggressive and dramatic features. 

    Satin Black Powdercoat. The Black Mamba's satin black powdercoat finish and machined silver beadlock accents perfectly capture the stealthy, sleek and dangerous palette of its namesake. A powdercoat finish lasts through road debris, poor weather conditions and extreme temperatures, making sure the Mamba looks just as good after 10,000 miles as when you installed them.

    One-Piece Aluminum. The Mamba's lightweight-but-tough characteristics come from its innovative one-piece cast aluminum design. Gracing the scales at just 38.4 lbs, the Mamba can hold up to 2,500 lbs. per wheel, making it perfect for your heavy-duty truck's new, beefy tires.

    Offset. The Raceline Mamba Black 6-Lug Wheel comes available with an offset of +25mm, +18mm, or 0mm. A high positive offset moves the inner wheel hub further to the outside, bringing your wheel closer to the fender well. A 0mm offset brings the inner wheel hub further to the inside, bringing your wheel further out from inside the fender well for a wider stance.

    Application. The Raceline Mamba Black 6-Lug Wheel measures 20x9 and comes available for any 2014-2018 Chevy Silverado.
