ARRMA Assembled Oil Filled Differential 30T 0.8Mod, 3000cSt Oil (2pcs) - GROM, ARA311193

The ARRMA Assembled Oil Filled Differential (30T 0.8Mod 3000cSt Oil) has garnered mixed feedback from customers, primarily centered around performance, quality, and price. Many users appreciate the high quality of the differentials, praising their robust metal components and effective oil filling, which significantly outperforms the stock plastic diffs that come standard with many models. This enhancement is particularly noticeable in high-power applications, where these differentials are said to provide better handling and longevity. However, the reviews also reveal a common concern regarding the price. Some customers feel that while the ARRMA diffs are top-notch, the cost may not justify their benefits when compared to more economical alternatives that offer similar performance. Users have suggested that for those on a budget, purchasing cheaper differentials along with upgraded drive cups and steel shafts could be a more cost-effective solution. Installation is generally reported as straightforward, which is a plus for hobbyists looking to upgrade their RC vehicles without technical difficulties. Despite some users noticing that the diffs are "lightly oiled" upon unpacking, they noted that adding personal choice fluids is essential for optimal performance, particularly under demanding conditions. In summary, while the ARRMA Assembled Oil Filled Differentials offer a notable upgrade in terms of quality and performance, their higher price point and the need for further lubrication tweaking may lead customers to seek alternative options if cost is a primary concern. **
