Review ACURA Rear Control Arm Left/right Oem fits RDX 2019–2020

The **Acura 52340-TJB-A00 (2019-2020 RDX Rear Control Arm, Left/Right)** and the **A911 (2019) Rear Control Arm** are precision-engineered suspension components designed to deliver superior handling, stability, and durability for Acura s flagship luxury SUVs and high-performance models. These control arms are integral to the vehicle s rear-wheel steering and adaptive suspension systems, ensuring optimal weight distribution, reduced body roll, and enhanced cornering precision. Crafted from high-grade, heat-treated steel, these arms feature a robust, powder-coated finish that resists corrosion and wear, even under demanding driving conditions, including off-road excursions or aggressive on-road performance. The **52340-TJB-A00** is specifically tailored for the **2019-2020 Acura RDX**, a vehicle renowned for its refined yet dynamic ride, where the rear control arms play a critical role in maintaining the RDX s signature balance between comfort and sportiness. Meanwhile, the **A911** is engineered for the **2019 Audi A9 (Quattro)**, a grand touring sedan where precision suspension geometry is paramount for delivering the seamless blend of luxury and performance that Audi enthusiasts expect. Both components incorporate **ball joints with sealed bearings**, ensuring smooth articulation and longevity while minimizing maintenance requirements. The **TJB-A00** variant for the RDX includes reinforced bushings optimized for the SUV s higher ground clearance and variable suspension travel, while the **A911** reflects Audi s engineering focus on low unsprung weight and minimal steering effort, contributing to the A9 s effortless handling. Whether installed in a high-mileage RDX undergoing a full suspension refresh or in a meticulously restored A9 seeking OEM-level accuracy, these control arms are designed to restore factory specifications with minimal deviation, ensuring that drivers experience the intended responsiveness and refinement for which these vehicles are celebrated. Their compatibility with aftermarket performance upgrades such as stiffer springs, adaptive dampers, or limited-slip differentials further underscores their versatility, making them a staple for both restoration projects and performance-oriented modifications.

### **Pros and Cons of buying a Specified OEM Acura/Infiniti Rear Control Arm (Part Numbers: 52340-TJB-A00 for 2019-2020 RDX and A911 for 2019)**

1. **Direct Fitment and Reliability** These are genuine OEM parts designed specifically for the 2019-2020 Acura RDX (RDX) and 2019 Infiniti QX60 (A911). They are engineered to match the factory specifications, ensuring proper fitment, alignment, and performance without compromising handling or suspension integrity.

2. **Durability and Longevity** OEM parts are built to withstand the demands of daily driving, including rough roads, aggressive cornering, and varying load conditions. They are typically made from high-quality materials, such as forged steel or heat-treated components, which resist wear and deformation better than aftermarket alternatives.

3. **Warranty Coverage** Purchasing from an authorized dealer or a reputable online retailer (e.g., RockAuto, PartsGeek, or a dealership) often includes a warranty, usually ranging from 12 months to a lifetime limited warranty for certain components. This provides peace of mind against premature failure.

4. **Compatibility with Factory Systems** The control arms are designed to work seamlessly with the rest of the suspension system, including bushings, ball joints, and sway bar links. This reduces the risk of premature wear on related components due to misalignment or improper fitment.

5. **Resale Value and Ownership Confidence** Using OEM parts when performing repairs or maintenance can enhance the vehicle s resale value and demonstrate to potential buyers that the car was well-maintained. It also reduces the likelihood of future issues stemming from inferior aftermarket parts.

6. **Access to Technical Support** OEM parts suppliers often provide detailed installation guides, torque specifications, and customer support for installation-related questions. This is particularly useful for DIYers or mechanics unfamiliar with the specific model.

7. **Consistency Across Models** The 2019-2020 RDX and 2019 QX60 share many suspension components, so purchasing the correct part ensures compatibility without cross-model confusion.

---

1. **Higher Cost** OEM parts are significantly more expensive than aftermarket alternatives. For example, a single rear control arm (left or right) for these models can cost between **$200 $400 per unit**, depending on the retailer. This can be a substantial investment, especially if multiple parts are needed.

2. **Longer Lead Times** OEM parts may not be immediately available, particularly if ordering from a dealer or specialized supplier. Lead times can range from a few days to several weeks, which may delay repairs if you re in a hurry.

3. **Potential for Overkill** If the control arm is only showing minor wear or is failing due to a single bushing, replacing the entire arm may be excessive. In such cases, aftermarket or remanufactured parts could be a more cost-effective solution.

4. **Limited Customization** Unlike aftermarket parts, OEM control arms do not offer performance upgrades (e.g., stiffer bushings, adjustable geometry). If you re looking to enhance handling or off-road capability, aftermarket options may provide better flexibility.

5. **Disposal of Old Parts** If you re replacing the control arm yourself, you ll need to properly dispose of the old part. Some auto shops or recycling centers may charge fees for scrap metal, adding to the overall cost.

6. **Potential for Counterfeit Parts** When purchasing from third-party sellers (e.g., eBay, Amazon, or unverified online marketplaces), there is a risk of receiving counterfeit or salvaged parts. Always verify the seller s reputation and part authenticity to avoid receiving substandard components.

7. **Installation Complexity** While not inherently difficult, replacing a rear control arm requires lifting the vehicle, removing the wheel, and often disconnecting the driveshaft or brake components. If you re not experienced with suspension work, this job may be better left to a professional mechanic.

The **2019-2020 Acura RDX (52340-TJB-A00) and 2019 Infiniti QX60 (A911) rear control arms** are high-quality OEM components that offer reliability, durability, and proper fitment. They are ideal for owners who prioritize **long-term performance, warranty coverage, and peace of mind**, especially if the vehicle is still under warranty or if you plan to keep it for an extended period.

However, the **higher cost and potential lead times** make them less ideal for budget-conscious buyers or those who need a quick repair. If the control arm is only partially worn or if you re open to aftermarket options, alternatives like **remanufactured parts (e.g., from Dorman or Febi) or performance-oriented bushings** could provide a more affordable solution without sacrificing quality.

---

- You want the best possible fitment and longevity.

- The vehicle is still under warranty, and you want to avoid voiding it (though replacing suspension parts typically doesn t void the powertrain warranty).

- You re performing a full suspension refresh or restoring the car to factory specifications.

- You have access to a warranty and are willing to pay the premium for reliability.

- You re on a tight budget and the control arm is only showing minor wear.

- You re open to performance upgrades (e.g., stiffer bushings for better handling).

- You can find a reputable remanufactured part (e.g., from **Dorman, Febi, or ACDelco**) that offers similar durability at a lower cost.

- You re comfortable with installation and want to save labor costs.

- **Authorized Dealers:** Most reliable but expensive (e.g., Acura/Infiniti dealership parts departments).

- **Online Retailers:** **RockAuto, PartsGeek, or Amazon** (verify seller ratings and part authenticity).

- **Remanufacturers:** **Dorman, Febi, or ACDelco** for high-quality aftermarket alternatives.

- **Salvage Yards:** Only if you re certain the part is undamaged (risky for safety-critical components).

- If you re experienced with suspension work, DIY installation is feasible.

- If not, consult a **suspension specialist or dealership** to ensure proper alignment and torque specifications are met.

**Final Verdict:** For most owners, the **OEM part is the best choice** for long-term reliability, especially on a luxury SUV like the RDX or QX60. However, weigh the cost against your budget and needs before purchasing. Always cross-reference part numbers and consult your vehicle s service manual for exact specifications.
