### **Pros and Cons of buying a H18687 Idler Arm for 1967 1970 Ford Mustangs**

1. **Direct Fitment** This idler arm is specifically designed for the 1967 1970 Ford Mustang, ensuring compatibility with the suspension geometry of these models. It eliminates the need for modifications or conversions, making installation straightforward.

2. **Improved Durability** The H18687 is typically made from high-quality materials, such as stamped steel or reinforced components, which can withstand the stresses of daily driving better than OEM parts prone to rust or wear.

3. **Better Performance** A properly functioning idler arm helps maintain proper suspension alignment, reducing unnecessary wear on tires, bushings, and other suspension components. This can lead to smoother handling and longer-lasting parts.

4. **Easier Installation** Since it is a direct replacement, the part is designed to drop into place without requiring extensive modifications. This saves time and labor costs compared to aftermarket parts that may need additional adjustments.

5. **Reliability** Ford s original parts, even aftermarket reproductions, are generally reliable for their intended purpose. The H18687 is a well-documented part with a proven track record in Mustang applications.

6. **Aesthetic Consistency** If you prefer a stock look, this part maintains the original appearance of your Mustang s suspension, avoiding the need for custom or non-OEM styling choices.

7. **Widely Available** As a common Mustang part, the H18687 is easy to find from reputable suppliers, whether online (e.g., RockAuto, Summit Racing) or at local auto parts stores.

1. **Potential Rust Issues** Even aftermarket reproductions may not be as corrosion-resistant as modern parts. If your Mustang has been exposed to salt, moisture, or poor storage, the idler arm could still develop rust over time, requiring replacement sooner than expected.

2. **Limited Customization** Unlike aftermarket suspension upgrades, this part does not offer performance enhancements beyond basic functionality. If you re looking for stiffer bushings, adjustable components, or performance-oriented upgrades, this is not the right choice.

3. **Price Variability** While generally affordable, prices can vary depending on the supplier, brand, and whether it s a new or used part. Some aftermarket versions may be cheaper but could compromise on quality.

4. **Installation Challenges** If the surrounding suspension components (e.g., bushings, control arms) are worn or misaligned, replacing just the idler arm may not fully resolve handling issues. A full suspension inspection could be necessary.

5. **Availability of Alternatives** For enthusiasts seeking higher performance or modern materials (e.g., polyurethane bushings, billet steel), there are aftermarket options that may offer better long-term durability or adjustability.

6. **Potential for Counterfeit Parts** As with many Ford Mustang parts, there is a risk of purchasing counterfeit or low-quality replicas, especially from untrusted sellers. Always verify the supplier s reputation and product authenticity.

7. **Limited Longevity in Harsh Conditions** If your Mustang is driven in extreme environments (e.g., off-road, heavy towing, or aggressive driving), the idler arm may wear out faster than expected, requiring more frequent replacements.

### **Conclusion**

The **H18687 idler arm for 1967 1970 Ford Mustangs** is a solid choice for drivers seeking a **direct, reliable, and easy-to-install replacement** for a worn or damaged OEM part. It excels in **simplicity, fitment, and basic functionality**, making it ideal for restorations, routine maintenance, or those who prioritize stock aesthetics. However, it is not a high-performance upgrade and may still require attention to rust or surrounding suspension wear over time.

If your primary goal is **improved handling, durability, or customization**, exploring aftermarket alternatives (e.g., Bilstein, Fox, or performance-oriented suspension kits) could be more beneficial. For most casual drivers or restorers, however, the H18687 provides a **cost-effective and practical solution**.

---

### **Recommendation**

- You need a **direct replacement** for a broken or rusted OEM idler arm.

- You want a **simple, no-fuss installation** without modifying other suspension components.

- Your Mustang is primarily driven on **paved roads** with moderate use.

- You prefer **stock appearance** and don t require performance upgrades.

- You re driving in **harsh conditions** (off-road, salt environments, heavy loads) and need **superior durability**.

- You want **adjustable or high-performance suspension components** (e.g., coilovers, poly bushings).

- You re open to **aftermarket brands** that offer warranties or better materials (e.g., Bilstein, Eibach, or local Mustang specialty shops).

**Final Tip:** Always inspect the **bushings, control arms, and steering components** alongside the idler arm, as related wear can affect performance. If budget allows, pairing this part with **new bushings or a suspension alignment** will maximize its benefits.
