### Pros and Cons of Buying a Toyota 3712022860 JZX90 Driveshaft (JDM)
#### **Pros:**The Toyota 3712022860 driveshaft, commonly used in JDM (Japanese Domestic Market) models like the Toyota Supra (A80/A90) and early Celica GT-Four, has several advantages:
1. **Compatibility and Fitment** This driveshaft is designed specifically for the JZ engine family (3.0L V6) in Toyota s JZX90 platform, ensuring a precise fit without modifications. It is widely used in Supra (MKIII and early MKIV) and Celica GT-Four WR300/WR301 applications.
2. **Durability and Build Quality** Toyota driveshafts are known for their robust construction, often featuring heavy-duty materials like forged steel or high-strength steel tubing. The 3712022860 is no exception, making it suitable for both daily driving and light performance applications.
3. **Aftermarket Support** Due to its popularity, this driveshaft is well-documented in tuning communities. Replacement parts, balancing services, and universal joints (UJs) are readily available, making maintenance and upgrades easier.
4. **Reliability in Stock Form** In stock form, this driveshaft is designed to handle the power output of naturally aspirated JZ engines (around 200 250 hp) without excessive stress. It can also support mild turbocharged setups if properly supported by the rest of the drivetrain.
5. **Cost-Effective Replacement** Compared to aftermarket driveshafts, the genuine Toyota part is often more affordable than high-end custom builds, especially when sourced from reputable JDM parts suppliers or salvage yards.
6. **Universal Joint (UJ) Options** The driveshaft can be paired with high-quality aftermarket UJs (such as Quaife, Lamo, or Toyo Riken) to improve durability and reduce vibration, especially in high-performance applications.

#### **Cons:** While the 3712022860 driveshaft has many strengths, there are some drawbacks to consider:1. **Limited Power Handling in Stock Form** The stock driveshaft is not designed for extreme power outputs (e.g., 400 hp naturally aspirated or heavily turbocharged engines). Without reinforcement or a custom build, it may fail prematurely under heavy loads, particularly in aggressive driving or drifting applications.
2. **Weight Considerations** Like many stock Toyota driveshafts, this part can be heavier than aftermarket alternatives, which may slightly reduce acceleration and fuel efficiency in high-performance setups.
3. **Availability and Sourcing Challenges** Genuine Toyota driveshafts can be difficult to source, especially in regions outside Japan. Buyers may need to rely on salvage yards, online marketplaces (e.g., eBay, Facebook Marketplace), or JDM importers, which can introduce risks of counterfeit or damaged parts.
4. **Balancing Requirements** Driveshafts can develop an imbalance over time due to wear on the UJs or CV joints. This requires periodic balancing, which adds maintenance cost and effort. Aftermarket driveshafts often come pre-balanced, but stock parts may need this service.
5. **Compatibility with Modified Suspensions** If the vehicle has been modified with lowered suspension, wider tires, or drivetrain changes, the stock driveshaft angle may cause binding or premature wear. In such cases, a custom driveshaft or reinforced version may be necessary.
6. **Potential for Counterfeit Parts** Due to the driveshaft s popularity, there is a risk of purchasing counterfeit or low-quality replicas, particularly from untrusted sellers. Always verify the part s authenticity (e.g., check the OEM number, material, and supplier reputation).
7. **Limited Customization** Unlike aftermarket driveshafts, the stock 3712022860 offers little flexibility in terms of length, material, or joint selection. Custom builds require additional welding or machining, which can be costly.

### **Conclusion:**The Toyota 3712022860 driveshaft is a **solid, reliable choice** for JDM JZX90 applications (Supra, Celica GT-Four) in stock or mildly modified form. It offers a good balance of durability, fitment, and cost-effectiveness for daily drivers or lightly tuned vehicles. However, it is **not suitable for high-power applications** without reinforcement or a custom build.
For **naturally aspirated JZ engines (250 hp or less)** or **mildly turbocharged setups (up to 300 hp)**, the stock driveshaft can work well with proper maintenance (e.g., UJ upgrades, balancing). For **high-performance or drifting applications (350 hp)**, a reinforced or aftermarket driveshaft is strongly recommended to prevent failure.
---
### **Recommendation:**- **If your vehicle is stock or lightly modified (under 300 hp):** The 3712022860 driveshaft is a **good, budget-friendly option**, provided you source it from a reputable supplier and perform regular maintenance (UJ checks, balancing).
- **If your vehicle is heavily modified (turbocharged, high horsepower, or aggressive driving):** Invest in a **reinforced or aftermarket driveshaft** (e.g., from companies like **Dynalite, Toyo Riken, or custom fabricators**) to ensure longevity and safety.
- **For sourcing:** Purchase from **verified JDM suppliers, salvage yards with inspection services, or trusted online marketplaces** to avoid counterfeit parts. Always verify the part number and condition before buying.
- **For long-term reliability:** Consider upgrading the **universal joints (UJs)** to high-quality aftermarket units (e.g., Quaife, Lamo) and **balance the driveshaft** every 10,000 15,000 miles to prevent vibration-related wear.
**Final Verdict:** The 3712022860 is a **practical and cost-effective solution for stock-to-mildly-modified JZX90 applications**, but it is not a "one-size-fits-all" part for high-performance builds. Evaluate your power output and driving style before committing to purchase.
Little surface rust from some rain that came after we pulled it but in great shape. Can use this for half shaft jz swap or stock application back into oem Mark II.
