7886 X-Series Overdrive Gear Set

This product is an overdrive gear set for X‑Series transmissions, designed to change the gear ratio to deliver higher top‑end speed or altered power delivery characteristics. The precision‑machined gears are built to handle increased loads while maintaining smooth engagement and efficient drivetrain operation. Using this gear set shifts the drive ratio compared to stock gearing, which can improve acceleration or speed depending on the specific X‑Series vehicle application. It is compatible with Traxxas X‑Series models that use this overdrive gear design, and serves as a direct replacement or upgrade to tailor performance and restore drivetrain reliability.
