How does the anodised aluminium housing improve performance?
The Arrma Z-ARA220050 with anodised aluminium housing and steel face plate features a diff case body crafted from lightweight aluminium that’s anodised for added strength and corrosion resistance. This material choice reduces weight while maintaining rigidity, allowing the differential to withstand high torque loads and rough terrain. The precision manufacturing ensures a snug fit with internal gears and seals, reducing vibration and wear during operation. For RC enthusiasts pushing their vehicles to the limit, this aluminium upgrade offers a dependable foundation.
What makes the steel face plate a critical upgrade?
The hardened steel face plate included in the Arrma Z-ARA220050 Metal Diff Case Upgrade Aluminium/Steel adds a layer of protection to the differential assembly. Designed to resist deformation under pressure, the steel plate maintains gear alignment and prevents casing flex during acceleration and impact. This results in smoother power delivery and extended gear life. When paired with the aluminium housing, the steel face plate creates a robust enclosure that’s ideal for high-performance RC applications.
Is the rebuild process simplified with this upgrade set?
Absolutely. The Arrma Z-ARA220050 with gear shims and diff gaskets included comes as a complete rebuild kit, making it easy to service or upgrade your differential. The set includes two diff gaskets for sealing, four gear shims for spacing and alignment, and eight M3 x 8 mm button head screws for secure assembly. These components are precision matched to the diff case and compatible gear sets, ensuring a hassle-free installation. Whether you're converting from plastic or refreshing worn parts, this kit streamlines the process.
