Review MAZDA Rx-7 Fc Rear Sway Bar End Link fits 1989–1991

The **Mazda FC01-28-170 Rear Sway Bar End Link** from the **1989 1991 RX-7 FC (Frotter)** era is a precision-crafted suspension component designed to enhance handling, stability, and overall driving dynamics for this iconic rotary-powered sports car. This end link, part of the rear sway bar assembly, plays a critical role in reducing body roll during cornering by transferring lateral forces between the left and right sides of the rear axle, thereby improving traction and responsiveness. Engineered to fit the RX-7 s unique **FC chassis**, this end link is constructed from high-quality **steel**, heat-treated for durability and resistance to wear, ensuring long-lasting performance even under aggressive driving conditions. Its **ball-joint design** allows for smooth articulation, accommodating the natural movement of the rear suspension while maintaining consistent tension on the sway bar, which is essential for optimal weight transfer and tire grip. The **1989 1991 model-specific fitment** ensures compatibility with the RX-7 s suspension geometry, including the **live rear axle** and **multi-link setup**, making it a direct replacement for OEM parts that may degrade over time due to rust, fatigue, or wear. Whether restoring an original FC model or upgrading an existing setup, this end link is a vital component for maintaining the RX-7 s legendary **lightweight agility and precise handling**, which were hallmarks of Mazda s rotary engineering in the late 1980s. For enthusiasts seeking to preserve or refine their FC s performance, this part represents a straightforward yet essential upgrade that bridges the gap between stock reliability and enhanced driving dynamics.

**Pros and Cons of Buying a Mazda FC01-28-170 (1989 1991 RX-7 FC Rear Sway Bar End Link)**

The rear sway bar end link for a 1989 1991 Mazda RX-7 FC is a relatively straightforward and affordable part to source, especially if you're restoring or modifying your car. Here are the key advantages:

1. **Common Part** The FC01-28-170 is a widely available aftermarket and OEM part, meaning you won t struggle to find replacements. Many online marketplaces, auto parts stores, and Mazda specialty shops stock it.

2. **Easy Installation** Unlike some suspension components, this end link is designed for relatively simple installation. It typically requires basic tools (socket wrench, torque wrench, and possibly a pry bar) and doesn t require specialized equipment.

3. **Affordable Cost** Compared to other suspension upgrades or high-performance parts, a sway bar end link is inexpensive, usually costing between $20 and $60 depending on whether it s OEM, aftermarket, or upgraded (e.g., billet or reinforced versions).

4. **Improves Handling (If Upgraded)** While stock end links are functional, aftermarket versions (e.g., stiffer or adjustable links) can enhance cornering stability, reduce body roll, and improve overall driving dynamics especially if you re running a tuned suspension setup.

5. **Prevents Wear on Other Components** A failing sway bar end link can cause excessive stress on bushings, ball joints, and control arms. Replacing it proactively can extend the life of other suspension parts.

6. **DIY-Friendly** If you re comfortable with basic mechanical work, replacing this part yourself saves labor costs. Many tutorials and step-by-step guides are available online.

7. **Compatibility with Mods** If you ve already modified your RX-7 (e.g., lowered suspension, stiffer springs, or sway bars), upgrading the end links can help balance the changes and prevent binding or premature failure.

---

1. **Potential for Counterfeit Parts** Due to the part s popularity, there s a risk of purchasing low-quality or counterfeit aftermarket links. Cheap knockoffs may fail prematurely or lack proper heat treatment, leading to cracking or breakage under stress.

2. **Installation Challenges (If Rusty or Seized)** If the old link is corroded or seized to the sway bar or subframe, removal can be difficult. You may need penetrating oil, a torque wrench, or even a press to free it without damaging the threads or mounting points.

3. **Misalignment Risks** If not installed correctly (e.g., improper torque, misaligned with the sway bar), the new link could cause uneven wear on tires or suspension components. Double-checking alignment and torque specs is crucial.

4. **Limited Performance Gain (Stock Links)** If you re using stock or basic aftermarket links without further suspension tuning, the improvement in handling may be minimal. For noticeable differences, you d likely need to pair it with other upgrades (e.g., stiffer sway bars, adjusted camber, or better bushings).

5. **OEM Parts May Be Hard to Find** While aftermarket options abound, genuine OEM links can be scarce, especially for older RX-7 models. If you prefer OEM quality, you may need to source from a specialty dealer or salvage yard.

6. **Compatibility with Aftermarket Sway Bars** Some aftermarket sway bars (especially those designed for lowered or high-performance setups) may require specific end links. Using the wrong link could lead to binding or improper function.

7. **Time-Consuming for Beginners** While the job itself isn t complex, if you re new to suspension work, you might spend extra time researching the correct part numbers, torque values, and installation steps to avoid mistakes.

The **Mazda FC01-28-170 rear sway bar end link** is a practical and cost-effective part to maintain or upgrade your 1989 1991 RX-7 FC. It s an accessible DIY project that can prevent bigger suspension issues and, when upgraded, enhance handling. However, the key to success lies in sourcing a high-quality part, ensuring proper installation, and considering whether the upgrade aligns with your overall suspension goals.

If you re restoring the car to stock condition, an OEM or reputable aftermarket link will suffice. If you re tuning the suspension for better performance, investing in a stiffer or billet link (e.g., from brands like **Motegi, JE, or Koni**) could justify the extra cost. Always verify compatibility with your sway bar setup and follow torque specifications to avoid premature failure.

---

- **For Stock or Basic Maintenance:** Purchase a **reputable aftermarket link** (e.g., **Motegi, JE, or a trusted eBay seller**) or an **OEM replacement** if available. Ensure it matches the **FC01-28-170 spec** (or equivalent, such as **FC01-28-171** for some variants).

- **For Performance Tuning:** If you re running a **lowered suspension, stiffer sway bars, or aggressive camber**, opt for a **billet or reinforced end link** (e.g., **Motegi s billet links or Koni s performance links**) to handle increased stress.

- Use **penetrating oil** (PB Blaster, WD-40) if the old link is seized.

- **Torque to spec** (typically **30 40 ft-lbs** for the nut, but check your manual).

- **Inspect bushings** if they re worn, replace them alongside the link.

- **Check for binding** after installation by moving the sway bar manually to ensure smooth operation.

- **Online:** eBay, RockAuto, MazdaParts24, or specialty RX-7 forums (e.g., **RX-7.net, MazdaSpeed.com**).

- **Local:** Mazda specialty shops, auto parts stores (AutoZone, NAPA), or salvage yards.

- **Avoid:** Cheap no-name parts from unknown sellers, as they may fail under load. Always read reviews or ask for verification if buying from an individual.

**Final Verdict:** This is a **low-risk, high-reward** upgrade for any RX-7 FC owner. Prioritize quality over price, and treat it as part of a broader suspension maintenance or tuning plan for the best results.
