#### **Cons**

1. **Higher Cost Compared to Plastic or Basic Metal Parts** Premium swing arms like this one are more expensive than standard plastic or low-grade metal alternatives, which may be a barrier for budget-conscious hobbyists.

2. **Requires Proper Installation Knowledge** While installation is generally straightforward, improper alignment or mounting can lead to premature wear or failure. Users without mechanical experience may need guidance.

3. **Weight Consideration** Even though it s durable, the added weight of a high-quality swing arm may slightly reduce the vehicle s overall speed or agility, especially in lightweight or high-performance setups.
