Technical Performance
These washers represent the quality and engineering that ARRMA is known for throughout the RC hobby community. The 12x15.5x0.2mm dimensions have been specifically engineered to work seamlessly with ARRMA's drivetrain and mechanical assemblies found across their entire range of brushless and brushed RC trucks and buggies. The steel construction provides the strength needed to maintain proper spacing and alignment in critical areas like differential assemblies and gear mesh adjustments, which are absolutely crucial for optimal performance of your RC vehicle. Whether you're working with 1/10 scale monster trucks like the Granite or Big Rock, 1/10 scale short course trucks like the Senton, or 1/8 scale buggies and street bash trucks like the Typhon and Infraction, these washers deliver the precision fit and durability required for professional-quality maintenance. The 0.2mm thickness is thin enough for precise fine-tuning of gear mesh but substantial enough to maintain structural integrity under the loads experienced during high-speed racing or aggressive bashing. Each washer has been precision-manufactured to ensure consistent thickness and dimensional accuracy, eliminating the frustration of loose tolerances that can compromise performance.
