This hardened steel front slipper cup is engineered as a direct replacement or upgrade for the Kyosho Lazer ZX7 1/10th scale 4WD competition buggy. It serves as a critical component in the vehicle's drivetrain, specifically linking the slipper clutch to the front center driveshaft, ensuring robust and consistent power delivery to the front differential. Constructed from durable steel, this cup significantly enhances wear resistance and overall longevity compared to softer materials, making it an essential upgrade for competitive racing where reliability and minimal maintenance are paramount for peak performance.
