GPMMAG012-R Diff Housing ARRMA 3S/4S

GPMMAG012‑R Diff Housing ARRMA 3S/4S

The GPMMAG012‑R Diff Housing is a reinforced drivetrain upgrade designed for ARRMA 3S and 4S vehicles. Precision‑engineered from high‑quality materials, this differential housing replaces the stock unit to provide increased strength, rigidity, and durability, helping your vehicle handle aggressive driving, high torque loads, and rough terrain with confidence.

The robust construction protects internal gears and drivetrain components from impacts and wear while maintaining proper gear alignment under load. This results in smoother power transfer, improved reliability, and reduced risk of drivetrain failures during high‑stress use. The red anodized finish adds corrosion resistance and a bold custom look that complements other upgraded components on your ARRMA.
