This high-quality kit is crafted to replace the stock idler arms, which are notorious for wear, rust, and premature failure common issues in these vintage vehicles due to their age and exposure to harsh driving conditions. The AA-15 kit features precision-machined components, including a **heavy-duty idler arm assembly** with a reinforced pivot bushings or bearings (depending on the specific variant), ensuring smooth articulation and reduced binding. The idler arms are fabricated from **high-strength steel**, heat-treated for durability, and designed to maintain proper alignment of the steering linkage, critical for accurate wheel tracking and responsive handling.

Perfect for both restoration projects and modernized builds, the AA-15 idler arm kit bridges the gap between classic charm and contemporary durability, ensuring your Tri-Five turns heads on the road while delivering the smooth, predictable handling it deserves.

### Pros and Cons of Buying an AA-15 Idler Arm Kit for a 1955-57 Chevrolet Tri-Five (NOS)

1. **Improved Handling and Ride Quality** A properly functioning idler arm ensures even tire wear and better alignment, leading to a smoother, more responsive ride. Worn or broken idler arms can cause uneven tire wear, excessive vibration, and poor steering feel.

2. **Prevents Further Damage** If the idler arm is cracked, bent, or seized, it can force the steering linkage out of alignment, leading to more expensive repairs down the line. Replacing it early avoids compounding issues.

3. **Restores Originality (If NOS)** A new-old-stock (NOS) idler arm kit ensures you re not using a reproduction part that may not match the original fit, finish, or materials. This is particularly important for enthusiasts who prioritize authenticity in a classic car.

4. **Durability and Performance** High-quality idler arms (even NOS) are built to last, reducing the likelihood of premature failure. This is especially beneficial in a daily driver or a car that sees regular use.

5. **Easier Installation** Since NOS parts are designed for the specific model, they typically fit without extensive modification, making the installation process cleaner and more straightforward compared to aftermarket alternatives.

6. **Aesthetic Consistency** If you re maintaining the car in showroom condition, NOS parts help preserve the original appearance without the need for aftermarket replacements that may not blend in.

7. **Peace of Mind** Knowing the part is new (even if NOS) eliminates concerns about hidden wear or failure, which can be a risk with used or salvaged components.

1. **Cost** NOS parts are often more expensive than aftermarket or reproduction alternatives. While they may be priced reasonably for a classic car, the cost can still be a significant investment, especially if you re restoring multiple components.

2. **Limited Availability** Finding NOS parts for older vehicles can be challenging, particularly if the manufacturer no longer produces them. This may require sourcing from specialty suppliers, which could involve shipping delays or higher prices.

3. **Potential for Overkill** If the idler arm is only slightly worn or the car is primarily a weekend project, replacing it with a NOS kit might be unnecessary. In such cases, a used or aftermarket part could suffice without the premium cost.

4. **Installation Complexity** While NOS parts fit well, some classic cars require careful alignment and adjustment after replacement. If you re not experienced with suspension work, you may need to pay a mechanic to ensure proper setup, adding to the cost.

5. **Mixed Quality in NOS Parts** Not all NOS parts are created equal. Some may have been stored improperly, leading to rust or degradation. Inspecting the parts upon receipt is crucial to ensure they meet your expectations.

6. **Time-Consuming Restoration** If you re restoring the car and replacing multiple NOS components, the process can take longer than using aftermarket parts, which are often quicker to install.

7. **Market Fluctuations** The price of NOS parts can vary based on demand and availability. If you re on a tight budget, prices might rise unexpectedly, making it harder to stick to your original plan.

### **Conclusion and Recommendation**

Buying an **AA-15 idler arm kit (NOS) for a 1955-57 Chevrolet Tri-Five** is a solid choice if you prioritize **authenticity, durability, and long-term reliability**. The benefits in terms of handling, ride quality, and preventing further damage outweigh the higher cost for most enthusiasts who own or restore classic cars. NOS parts ensure you re getting a genuine component that fits perfectly and maintains the car s original character.

However, if you re working with a limited budget or the car is primarily a project vehicle with occasional use, an **aftermarket or used replacement** could be a more practical alternative. Aftermarket kits are often more affordable and widely available, and a well-maintained used part can work just as well if inspected thoroughly.

- **If you value originality and don t mind the cost**, go with the **NOS AA-15 idler arm kit**. It s a worthwhile investment for a classic car, especially if you re restoring or maintaining it to showroom condition.

- **If budget or convenience is a concern**, consider a **high-quality aftermarket kit** (such as those from EBC, Moroso, or other reputable brands) that still provides reliable performance without the NOS premium.

Ultimately, the decision depends on your priorities whether you re aiming for perfection or practicality. For a Tri-Five, the NOS option is the best choice for those who appreciate the finer details of classic car restoration.
