Review MERCEDES benz 2012 2020 Hood Support Strut Pair Oem fits SL55 SL63 SLC SLK AMG 2022–2023

The **Mercedes-Benz 1729800064 (2012 2020 SLK 200/230/350/55 AMG) and 2022 2023 SL55/SL63 AMG Hood Strut** is a precision-engineered suspension component designed to elevate the driving dynamics, aesthetic appeal, and long-term reliability of Mercedes-Benz roadsters and high-performance AMG models. Crafted from high-grade materials and engineered to exacting specifications, this strut is a direct replacement for the original equipment part, ensuring seamless integration with the vehicle s chassis while maintaining the iconic balance of sporty agility and refined comfort that Mercedes-Benz is renowned for. The 1729800064 strut is meticulously calibrated to support the SLK s lightweight, two-seater architecture, where precision suspension tuning is critical for both handling responsiveness and passenger comfort during spirited maneuvers or daily commutes. For the more powerful AMG variants such as the SL55 (with its 5.5-liter supercharged V8) and SL63 (powered by a twin-turbocharged 6.2-liter V8) this strut is reinforced to handle the increased load and dynamic forces generated by these high-performance engines, ensuring optimal ride quality and stability even at high speeds or during aggressive cornering.

Beyond its functional superiority, this hood strut also plays a pivotal role in the vehicle s visual identity. The SLK and SL series are celebrated for their sleek, aerodynamic profiles, and the hood strut often a prominent feature contributes to the car s aerodynamic efficiency and aerodynamic styling cues. The 2022 2023 SL55 and SL63 AMG models, in particular, feature a more aggressive and muscular design language, and the updated strut is designed to complement this evolution, maintaining the brand s signature blend of luxury and performance. Constructed with durability in mind, the strut is built to withstand environmental stressors, including UV exposure, road debris, and temperature fluctuations, which can degrade plastic and rubber components over time. This ensures that the hood remains securely latched, reducing the risk of accidental openings during high-speed driving or sharp turns a critical safety consideration for roadsters where the windshield and hood play a vital role in aerodynamic stability.

For enthusiasts and mechanics alike, the 1729800064 strut represents a straightforward yet impactful upgrade or replacement option. Its compatibility spans multiple model years, making it a versatile choice for owners looking to restore their SLK or SL AMG to factory specifications or enhance its performance. The installation process is designed to be efficient, with clear alignment guides and mounting points that align with Mercedes-Benz s engineering standards, minimizing the risk of misalignment or improper fitment. Whether used in a routine maintenance service, a restoration project, or as part of a performance tuning package, this strut exemplifies Mercedes-Benz s commitment to quality and precision, ensuring that every detail from the suspension to the styling contributes to the ultimate driving experience.

### **Pros and Cons of Buying a Mercedes-Benz SLK (2012 2020) and SL55/SL63 AMG (2022 2023) with a Hood Strut Issue**

---

### **Mercedes-Benz SLK (2012 2020) Overview**

1. **Sporty Two-Seater Design** The SLK is a lightweight, open-top roadster with a sleek, aggressive stance that appeals to enthusiasts who prioritize driving dynamics over practicality.

2. **Comfortable Ride** The suspension is well-tuned for both city and highway comfort, with adaptive damping (on later models) that adjusts to road conditions.

3. **Powerful Engines (Pre-AMG)**

- The **M176 (3.5L V6)** in the SLK 350 (2012 2016) produces **306 hp** and offers smooth, torquey performance.

- The **M272 (3.0L V6 Turbo)** in the SLK 550 (2017 2020) delivers **405 hp**, making it quicker and more spirited.

- The **M276 (4.0L V8)** in the SLK 63 AMG (2017 2020) generates **455 hp**, offering near-supercar-like acceleration (0 60 mph in 4.3 seconds).

5. **Convertible Convenience** The **electronic soft-top** is quick to deploy and provides good weather protection, though it s not as weather-sealed as a hardtop.

6. **Luxury Interior** High-quality materials, ambient lighting, and advanced infotainment (especially on later models with MBUX) enhance the driving experience.

7. **Resale Value (AMG Models)** The SLK 63 AMG holds value better than base models due to its performance credentials.

8. **Driving Enjoyment** The steering is precise, the chassis is nimble, and the AMG models feel more engaged than most modern roadsters.

- Symptoms include the hood **dropping suddenly**, **not staying open**, or **requiring constant adjustment**.

- **Repair cost**: $500 $1,200 depending on whether parts or labor are included.

- **Workaround**: Some owners modify the strut with **3D-printed parts** or **aftermarket solutions**, but this is not a permanent fix.

5. **Limited Practicality**

6. **Electrical Issues**

- Older SLK models (pre-2017) have **known electrical quirks**, such as **infotainment glitches, sensor failures, or starter relay issues**.

- AMG models are more refined but still not immune to **software bugs** (e.g., MBUX touchscreen freezes).

7. **Discontinued Model**

- The SLK was **discontinued in 2020**, meaning **longer wait times for parts** and **fewer dealership technicians** familiar with the platform.

8. **Depreciation**

- The SLK has **declined significantly in value**, especially compared to rivals like the Porsche Boxster or BMW Z4.

- **AMG models hold value better**, but even they depreciate faster than a used Porsche or Audi TT.

1. **Supercar-Level Performance**

- The **SL63 AMG (2022 2023)** comes with a **4.0L V8 (M177) producing 557 hp** and **516 lb-ft of torque**, paired with a **9-speed AMG SPEEDSHIFT DCT**.

5. **AMG Exclusivity**

- The **SL63 AMG** is one of the **fastest production coupes** in its class, rivaling the Porsche 911 Turbo S.

3. **Depreciation**

- **Rear-wheel bias** means **understeer can be an issue** at high speeds.

5. **Convertible Alternative Missing**

6. **Fuel Consumption**

- The **V8 SL63 gets 12 14 MPG city / 18 20 MPG highway**, making it **less efficient than a hybrid or electric sports car**.

7. **Resale Market Uncertainty**

- The **SL-Class is being phased out** (Mercedes is focusing on electric models like the EQS).

- Future **parts availability** may become an issue as production ends.
