Instantly improve the rigidity and appearance of your RC10B6.3 or RC10B6.3D servo mount with the 1up Racing HD Carbon Fiber Servo Mount Brace! These are milled from high-quality 3mm thick glossy carbon fiber then finished with chamfers and a beautifully engraved 1up logo on the top side. A direct replacement for the stock piece, this bolts in place using your kit’s hardware, or upgrade to our UltraLite Perfect Center Screws to truly 1up your car’s looks!
