( Manufacturer Part Number: 55226AL500 ), ( Part Type: Suspension Bolt ), ( Country Of Origin: Japan )
The **Infiniti G35 (350Z) Rear Suspension Lower Link Bolt (Part Number: 55226-AL500, Model Years: 2003 2007)** is a precision-engineered component designed to maintain the structural integrity and handling dynamics of one of the most iconic rear-wheel-drive sports sedans of its era. This bolt serves as a critical linkage in the vehicle s multi-link rear suspension system, anchoring the lower control arm to the subframe while allowing for controlled articulation under load. Crafted from high-grade, heat-treated steel, it is engineered to withstand the rigors of daily driving, aggressive cornering, and off-road excursions, ensuring consistent alignment and minimizing unwanted movement that could compromise ride quality or tire wear. The bolt features a **12mm hex head** with a **fine-threaded design**, optimized for secure fastening with the appropriate torque specification typically around **80 100 ft-lbs** to prevent loosening during dynamic driving conditions. Its robust construction also includes a **smooth, corrosion-resistant finish**, protecting against environmental elements like road salt, moisture, and debris that could accelerate wear or compromise structural integrity over time. Whether replacing a worn-out bolt due to fatigue, addressing a suspension noise issue, or upgrading for enhanced durability, this part is a direct fit for the G35 s rear suspension, ensuring proper function of the lower control arm and maintaining the vehicle s sport-tuned balance. For enthusiasts and mechanics alike, sourcing an OEM-quality bolt guarantees compatibility with the factory suspension geometry, preserving the handling precision and driving dynamics that made the G35 a standout in its class.
### **Pros and Cons of Buying a Used Infiniti G35 (2003-2007) Rear Suspension Lower Link Bolt (Part # 55226AL500)**
#### **Pros:**1. **Direct Fitment** This bolt is designed specifically for the 2003-2007 Infiniti G35 (and related models like the Nissan 350Z), ensuring compatibility without modification.
2. **Common Failure Point** Lower link bolts are a known wear item in these vehicles, especially in high-mileage or aggressive driving conditions. Replacing them early can prevent more costly suspension damage.
3. **Prevents Excessive Wear** A failing lower link bolt can cause uneven tire wear, poor handling, or even suspension failure. Replacing it proactively maintains ride quality and safety.
4. **Easily Replaceable** The part is straightforward to install, requiring basic tools and minimal mechanical skill. Many owners or mechanics can handle the job without professional help.
5. **Cost-Effective** Compared to full suspension rebuilds or alignment issues caused by worn suspension components, this bolt is relatively inexpensive.
6. **Improves Driving Feel** A properly functioning lower link ensures better weight distribution, reducing body roll and improving responsiveness, especially in sport-tuned vehicles.
7. **Prevents Secondary Damage** Ignoring a failing lower link bolt can lead to damage to the lower control arm, bushings, or even the subframe. Replacing it early avoids cascading repairs.
---
#### **Cons:**1. **Potential for Counterfeit Parts** Some aftermarket or eBay sellers may offer low-quality or fake bolts that fail prematurely. Buying from a reputable supplier (e.g., RockAuto, Dorman, or a trusted local parts store) reduces this risk.
2. **May Require Additional Work** If the bolt is seized or the threads are stripped, additional lubrication (PB Blaster, penetrating oil) or thread repair (Helicoil) may be needed before installation.
3. **Not a Permanent Fix for All Issues** If the lower control arm or bushings are already worn, replacing just the bolt may not fully resolve handling problems. A full suspension inspection is recommended.
4. **Installation Challenges** Some owners report difficulty accessing the bolt due to tight clearance or interference with other components. A jack and proper support may be necessary.
5. **Mixed Quality in Aftermarket Parts** While OEM or high-quality aftermarket bolts (e.g., Dorman, Fel-Pro) are reliable, cheaper alternatives may corrode or break over time.
6. **Time-Consuming for DIYers** If the vehicle has rusted or seized components, removing the old bolt could take longer than expected, especially in older cars.
7. **No Warranty on Used Parts** If purchasing from a private seller, there s no guarantee of the part s condition or authenticity, unlike buying from a dealer or online retailer with return policies.

### **Conclusion:**Buying a **2003-2007 Infiniti G35/Nissan 350Z rear suspension lower link bolt (55226AL500)** is a **smart, cost-effective preventive maintenance step** for vehicles with high mileage or signs of suspension wear. The bolt is a **common failure point** that, if neglected, can lead to more expensive repairs. The **pros far outweigh the cons**, especially when purchasing from a trusted source and addressing any related suspension issues simultaneously.
However, **potential cons** such as counterfeit parts, installation difficulties, or underlying suspension problems can be mitigated by:- **Buying from a reputable supplier** (e.g., RockAuto, Dorman, or a local parts store with return policies).
- **Inspecting the old bolt** for wear or corrosion before purchasing.
- **Checking for accompanying suspension wear** (e.g., bushings, control arms) and addressing them if needed.
- **Using proper lubrication** (e.g., anti-seize compound) during installation to prevent future seizing.
If the vehicle shows **clunking noises, uneven tire wear, or poor handling**, replacing the lower link bolt is a **practical and necessary repair** to maintain safety and performance.

### **Recommendation:****Purchase the bolt from a trusted online retailer (e.g., RockAuto, Dorman, or Amazon) or a local parts store with a return policy.** If possible, **inspect the old bolt** before buying to confirm it s the correct part and in poor condition. **Replace it as part of a broader suspension check**, including the **lower control arm bushings and ball joints**, if they show signs of wear. For DIYers, **follow a step-by-step guide** (e.g., from Haynes Manual or YouTube) and **use penetrating oil** if the bolt is seized. If unsure about installation, consult a mechanic to avoid damaging other components.
**Final Verdict:** **Worth buying and replacing** if the vehicle shows suspension issues, as it s an **affordable fix** that prevents more serious problems. Always prioritize **quality parts and proper installation** for long-term reliability.
