### Pros and Cons of buying a Suzuki 12353-33011 Crank Spacer for a 1972 1977 GT380

#### **Pros:**

1. **Compatibility and Fitment** This part is specifically designed for the 1972 1977 Suzuki GT380 engine, ensuring a proper fit without modification. It is a direct replacement for the original crankshaft spacer, which may have worn out or been damaged over time.

2. **Performance Benefits** A worn or incorrect crankshaft spacer can lead to excessive crankshaft endplay, causing noise, vibration, and potential damage to the engine components. Replacing it with an OEM or high-quality aftermarket part can restore proper crankshaft alignment, reducing wear on bearings, seals, and the crankshaft itself.

3. **Prevents Engine Damage** If the crankshaft is moving excessively due to a missing or improper spacer, it can lead to catastrophic failure, such as bearing seizure or damage to the oil pump. Installing this part helps maintain engine integrity.

4. **Ease of Installation** The spacer is a straightforward component to replace, requiring basic tools and mechanical knowledge. It typically involves removing the oil pump, flywheel (or clutch), and crankshaft pulley to access and replace the spacer.

5. **Cost-Effective Solution** Compared to major engine repairs, replacing a crankshaft spacer is relatively inexpensive. It is a preventative measure that can save money in the long run by avoiding more severe engine issues.

6. **Availability of Genuine and Aftermarket Options** While the Suzuki OEM part (12353-33011) is reliable, there are also reputable aftermarket alternatives that offer similar quality at a lower cost. Brands like Fel-Pro, Moroso, or other performance-oriented suppliers provide durable options.

7. **Improved Reliability** For classic or high-mileage GT380 engines, this part can extend the life of the crankshaft and related components, making the engine more reliable for continued use.

#### **Cons:**

1. **Potential for Counterfeit Parts** Purchasing from untrusted sellers (especially online marketplaces) may result in counterfeit or low-quality replicas. Always buy from reputable suppliers or dealerships to ensure authenticity.

2. **Installation Challenges** While the job is manageable for experienced DIYers, it requires careful attention to torque specifications and alignment. Improper installation (e.g., overtightening or misalignment) can cause issues like warped components or premature wear.

3. **Limited Longevity in Harsh Conditions** If the engine is subjected to extreme heat, poor lubrication, or heavy loads, the spacer may still wear out over time. Regular maintenance (oil changes, inspections) is essential.

4. **Cost of Associated Labor** If you re not comfortable performing the installation yourself, labor costs at a shop can add up, especially for classic cars where mechanics may charge premium rates.

5. **Mixed Quality of Aftermarket Parts** While some aftermarket spacers are high-quality, others may be made from inferior materials. Researching the brand and reading reviews can help mitigate this risk.

6. **Risk of Overlooking Underlying Issues** If the crankshaft or bearings are already worn, replacing just the spacer may not fully resolve the problem. A thorough inspection (or even an engine rebuild) might be necessary for long-term reliability.

7. **Limited Availability of OEM Parts** Suzuki no longer produces this part, so sourcing the genuine 12353-33011 may require searching used markets, eBay, or specialty suppliers. Aftermarket parts are often the only viable option.

### **Conclusion:**

The Suzuki 12353-33011 crankshaft spacer (or a high-quality aftermarket equivalent) is a practical and necessary upgrade for a 1972 1977 GT380 engine experiencing crankshaft endplay or noise. It is a cost-effective way to prevent further damage, improve reliability, and extend the engine s lifespan. However, the success of the installation depends on sourcing a genuine or reputable aftermarket part and ensuring proper installation techniques.

For most owners, the benefits outweigh the drawbacks, especially if the engine shows signs of crankshaft-related issues. If you re unsure about DIY installation, consulting a mechanic experienced with classic Suzuki engines is advisable.

### **Recommendation:**

- **Buy from a trusted source:** Purchase the OEM part (12353-33011) from a reputable dealer, eBay seller with positive feedback, or a classic parts supplier. If opting for aftermarket, choose a well-reviewed brand like Fel-Pro or Moroso.

- **Inspect the engine beforehand:** Check for worn bearings, cracks in the crankshaft, or other issues that may require additional attention.

- **Follow torque specifications:** Use a torque wrench and adhere to the manufacturer s recommended tightness for the flywheel, oil pump, and related components.

- **Consider professional help if needed:** If you lack experience with engine disassembly, a mechanic familiar with classic Suzukis can ensure a clean installation.

- **Maintain the engine afterward:** Regular oil changes and inspections will help ensure the spacer and crankshaft remain in good condition.

**Final Verdict:** This is a worthwhile upgrade for any GT380 with crankshaft concerns, provided you take care in sourcing and installing the part correctly.
