### **Pros and Cons of buying a Stewart-Warner United 48396 SW/64 Speedometer Cable (104 Square Drive, 5/8-18 Upper, 7/8-18 Lower)**

1. **High Quality and Durability** Stewart-Warner is a well-known brand in automotive parts, particularly for speedometer cables and drives. This model is designed for longevity, often outperforming cheaper alternatives in terms of resistance to wear and tear.

2. **Precision Engineering** The 104 square drive mechanism ensures smooth and accurate speedometer readings, reducing inaccuracies that can occur with worn or poorly made cables.

3. **Compatibility with Classic and Performance Vehicles** This cable is designed for vehicles with specific drive shaft sizes (5/8-18 upper, 7/8-18 lower), making it a reliable fit for older cars, muscle cars, and performance vehicles where precise speedometer function is critical.

4. **Easy Installation** The design is straightforward, and many users report that it can be installed without special tools, though alignment with the speedometer housing may require attention.

5. **Reliability in Harsh Conditions** The cable is built to withstand vibration, heat, and general mechanical stress, which is important for vehicles used in demanding conditions.

6. **Aftermarket Support** Stewart-Warner parts are widely available through automotive supply stores, online retailers, and specialty shops, making replacements or upgrades easy to source.

7. **Cost-Effective for Long-Term Use** While the upfront cost may be higher than generic cables, its durability often means fewer replacements over time, saving money in the long run.

1. **Higher Initial Cost** Compared to no-name or budget-brand speedometer cables, this part is more expensive. For budget-conscious buyers, this could be a drawback if they are unsure of its necessity.

2. **Potential Overkill for Modern Vehicles** Many newer cars use electronic speed sensors rather than mechanical cables. If the vehicle already has an electronic speedometer, this cable may not be needed, making the purchase unnecessary.

3. **Limited Availability in Some Regions** While Stewart-Warner parts are widely available in the U.S. and Europe, they may be harder to find in other markets, requiring online ordering or shipping delays.

4. **Installation Challenges for DIYers** While not overly difficult, improper alignment or tension can lead to inaccurate speedometer readings. Those unfamiliar with speedometer cable installation may struggle without guidance.

5. **Potential for Misalignment** If not installed correctly, the cable can bind or misalign, causing erratic speedometer behavior. This requires careful attention during installation.

6. **Weight Consideration** The cable is heavier than some modern alternatives, which may not be an issue for most vehicles but could be a minor inconvenience in high-performance or lightweight applications.

7. **Compatibility Issues with Non-Standard Setups** If the vehicle has modified drivetrains (e.g., custom gear ratios, aftermarket speed sensors), the cable may not integrate perfectly without additional modifications.

The Stewart-Warner United 48396 SW/64 speedometer cable is a high-quality, reliable choice for vehicles that require a mechanical speedometer drive. Its precision engineering, durability, and compatibility with classic and performance vehicles make it a strong option for those who prioritize accuracy and longevity. However, its higher cost and potential overkill for modern electronic speedometers may deter some buyers. Additionally, DIY installation requires careful attention to ensure proper function.

For **classic cars, muscle cars, or performance vehicles with mechanical speedometers**, this cable is highly recommended due to its dependability. For **modern cars with electronic speed sensors**, it is unnecessary and may not be worth the investment.

- **Buy it if:** You have a vehicle with a mechanical speedometer (especially older models), you value precision, and you re willing to pay for a durable, long-lasting part.

- **Skip it if:** Your vehicle uses an electronic speed sensor, you re on a tight budget, or you re unsure about installation complexity.

- **Alternative Consideration:** If cost is a concern, research high-quality aftermarket brands (e.g., Moroso, Delco) that offer similar performance at a lower price. Always verify compatibility with your specific vehicle before purchasing.
