Description
The Redcat Racing RER39670 is a high-torque internal gear upgrade specifically designed for 1/18 scale crawlers. This set provides a massive 20.52:1 gear reduction, significantly lowering the vehicle’s top speed in exchange for extreme low-end torque and precision control. Made from hardened steel, these gears are built to replace the stock plastic or lower-grade metal internals, making your drivetrain much more resilient to the stresses of technical rock crawling and high-power brushless systems.
