Review SUBARU Crosstrek Rear Sway Bar Stabilizer Oem fits XV 2013–2017

The **Subaru 13-14-15-16-17 637362 (2013-2017) XV Crosstrek Rear Sway Bar Stabilizer (16mm)** is a precision-engineered suspension component designed to enhance the handling, stability, and overall driving dynamics of your Subaru XV Crosstrek. This high-quality rear sway bar is specifically tailored to fit the 2013 through 2017 model years of the XV Crosstrek, ensuring a perfect match with the vehicle s suspension geometry and mounting points. Crafted from durable, high-grade steel, the sway bar is built to withstand the rigors of daily driving, off-road adventures, or spirited on-road performance, delivering consistent performance over an extended period. The **16mm diameter** design provides an optimal balance between stiffness and compliance, reducing body roll during cornering and improving traction by minimizing uneven tire loading. This stabilizer works in tandem with the front sway bar to create a more composed and predictable ride, particularly in tight turns, aggressive maneuvers, or when carrying additional weight. Whether you re navigating winding mountain roads, tackling rough terrain, or simply seeking a more engaging driving experience, this sway bar helps maintain lateral stability while reducing excessive lean. Its robust construction and precise fitment ensure long-lasting durability, making it an ideal upgrade for those looking to refine their Crosstrek s suspension characteristics without compromising reliability. Installing this sway bar is a straightforward process, often requiring minimal tools, and it can be easily integrated into routine maintenance or suspension tuning projects. By reinforcing the rear axle s resistance to roll, this component not only elevates the driving experience but also contributes to safer handling in various driving conditions.

Buying a **Subaru 13-14 15-16 17 637362 (2013-2017 XV Crosstrek) rear sway bar stabilizer (16mm)** can be a practical upgrade for improving handling, but it comes with both advantages and drawbacks. Below is a detailed breakdown:

### **Pros of Upgrading the Rear Sway Bar**

1. **Improved Handling and Stability** A stiffer sway bar reduces body roll during cornering, making the Crosstrek feel more planted and responsive, especially on twisty roads or aggressive driving.

2. **Better Weight Distribution** The stock sway bar is relatively soft, which can lead to excessive body lean in turns. A stiffer bar helps counteract this, improving traction and reducing understeer.

3. **Enhanced Off-Road Capability** On rough terrain, a stiffer sway bar can reduce excessive movement, helping maintain tire contact with the ground and improving stability over uneven surfaces.

4. **Compatibility with Other Modifications** If you ve already upgraded suspension components (e.g., coilovers, lower springs), a stiffer sway bar can complement those changes for a more balanced setup.

5. **Easy Installation** The sway bar is a relatively straightforward bolt-on part, requiring minimal tools and time to install, especially if you have basic mechanical experience.

6. **Cost-Effective Upgrade** Compared to full suspension overhauls, a sway bar upgrade is inexpensive and provides noticeable improvements without requiring major modifications.

### **Cons of Upgrading the Rear Sway Bar**

1. **Potential Over-Steer Risk** A stiffer sway bar can make the rear end feel too tight, leading to oversteer (rear-wheel slide) in aggressive driving situations, particularly if the front suspension isn t properly balanced.

2. **Ride Comfort Sacrifice** Stiffer sway bars can make the ride feel harsher, especially on rough roads or over speed bumps, as they reduce some of the suspension s natural damping.

3. **Stock Fitment Limitations** The 16mm sway bar may not be a direct drop-in replacement for all years/models in the 2013-2017 Crosstrek range. Some versions may require slight adjustments or additional hardware (e.g., spacers, extended arms).

4. **Possible Noise or Rattles** If the sway bar isn t properly torqued or if there are loose components in the suspension, it could introduce clunks or rattles, especially over bumps.

5. **Limited Performance Gain for Casual Drivers** If you primarily drive on smooth roads or highways, the benefits of a stiffer sway bar may be minimal compared to the stock setup.

6. **Compatibility with Stock Bushings** If the sway bar arms or bushings are worn, upgrading just the bar may not fully address handling issues. Replacing bushings or arms simultaneously could be necessary for optimal results.

### **Conclusion**

Upgrading the rear sway bar on your **2013-2017 Subaru XV Crosstrek** is a worthwhile modification for drivers who prioritize handling, off-road stability, or plan to pair it with other suspension upgrades. The benefits in cornering feel and traction are real, but the trade-off in ride comfort and potential oversteer risk should be considered. If you re already running a firmer suspension setup (e.g., coilovers, lower springs), the sway bar upgrade will complement those changes effectively.

- **Check compatibility** Ensure the 16mm sway bar is a direct fit or requires minimal adjustments for your specific year/model.

- **Pair with other upgrades** If you notice excessive body roll, consider upgrading front sway bars or bushings as well.

- **Test before committing** If possible, borrow or rent a similar sway bar to test its effect on your driving style before purchasing.

- **Maintain proper torque specs** Ensure all bolts are tightened to manufacturer specifications to avoid rattles or premature wear.

### **Recommendation**

If you re looking to **enhance handling without a full suspension rebuild**, the **16mm rear sway bar upgrade is a solid choice**, especially if you enjoy spirited driving or off-roading. However, if you value a plush, comfortable ride, the stock sway bar may suffice. For the best balance, consider:

- **A 16-18mm sway bar** (if available for your model) for a slightly softer but still stiffer feel.

- **Upgrading bushings** alongside the sway bar to reduce noise and improve longevity.

- **Testing on a track or rough terrain** to confirm the sway bar s effect matches your expectations.

Ultimately, this is a low-risk, high-reward modification that can significantly improve your Crosstrek s performance with minimal effort.
