Rikavim Differentials Editorial Review
The Steel Differential Gear Set is a robust upgrade for ARRMA 1/10 models such as the Big Rock, Granite, Vorteks, Senton 3S BLX, and Kraton/Outcast 4S BLX. Customers have praised the quality of the gear set, highlighting the use of hardened steel that promises durability and longevity. Many users report that the installation process is straightforward, and the fitment aligns seamlessly with the existing components of their RC vehicles. Some users, however, noted an initial period where the gears felt tight and produced grinding noises, suggesting a break-in period is necessary. Once past this stage, many users found the gears to perform excellently, especially under higher electrical loads, such as 100C 3S batteries. While the majority are satisfied with the performance of the differential gear set, some concerns were raised regarding the vulnerability of the screws, as they strip easily during assembly, and the set does not include all internal components for a complete differential, which customers should be aware of prior to purchase. Nevertheless, for those looking to restore or upgrade their ARRMA vehicles, many agree that this gear set represents an improvement over the stock alternatives. **
