The Exotek Grom/NASCAR Aluminum Lightweight Spur Gear is a high-performance upgrade designed for the Arrma Grom and Losi NASCAR series. Crafted from hard-anodized 7075 aluminum, this spur gear is significantly lighter than the stock steel counterpart, weighing only 5 grams compared to 12 grams. This reduction in weight allows for higher motor RPMs and cooler operating temperatures, enhancing overall drivetrain performance. Its precision-engineered design ensures a perfect fit and smooth power transfer, while its wear-resistant construction provides durability for long-lasting performance. By minimizing rotational mass, the Exotek spur gear reduces drivetrain stress, leading to improved acceleration and responsiveness. This makes it an excellent choice for racers seeking to optimize their vehicle's performance and reliability.
