The Fox DHX2 Performance Elite [paid link] rear shock is a high-performance suspension component designed to provide superior control, comfort, and durability for aggressive riders. It is ideal for mountain bikers looking to enhance their bike’s performance on rough terrains. This article will cover the installation, maintenance, troubleshooting, and customization of the DHX2 Performance Elite [paid link], while also comparing it to similar models to help you make an informed decision.

Installation of the DHX2 Performance Elite Rear Shock

Installing the Fox DHX2 Performance Elite rear shock is straightforward but requires attention to detail. This shock comes with a coil spring, making it ideal for riders seeking a plush feel and consistent performance on challenging trails.

Tools Required:

• Torque wrench [paid link]
• 8mm Allen wrench [paid link]
• Shock pump
• Appropriate mounting hardware (compatible with your bike frame)
• Clean cloths

Step-by-Step Installation:

1. Prepare the Bike: Ensure your bike is securely positioned on a bike stand [paid link]. Remove the old shock if replacing one, and clean the shock mount areas to prevent dirt or grime from interfering with installation.
2. Check Compatibility: Confirm that the DHX2 Performance Elite shock is compatible with your bike’s frame. This includes ensuring the eyelet sizes, mounting positions, and shock length are suitable.
3. Install the Shock: Place the DHX2 shock into the rear triangle of your frame. The shock’s eyelets should line up with the mounting positions. If necessary, use the correct hardware provided by Fox or your bike manufacturer.
4. Tighten the Bolts: Use the torque wrench [paid link] to tighten the mounting bolts. Ensure each bolt is tightened to the manufacturer’s specified torque setting to avoid damaging the shock or bike frame.
5. Set the Sag: The sag is the amount the shock compresses under the rider’s weight. Using the shock pump, set the correct air pressure to achieve 30% of travel sag, which ensures the best performance and comfort.
6. Final Check: Ensure all bolts are securely tightened, and double-check the shock’s position. Perform a quick compression test by pushing down on the rear of the bike to ensure smooth operation.

Adjusting the DHX2 Performance Elite Rear Shock

The DHX2 Performance Elite shock offers extensive adjustment capabilities to tailor your ride to your specific needs. It features separate compression, rebound, and preload adjustments for ultimate customization.

Compression Adjustment:

• Low-Speed Compression: Adjusts how the shock behaves under slow movements, such as while pedaling or braking. A higher setting will make the bike feel firmer, which is ideal for rougher terrain. A softer setting improves comfort on smoother trails.
• High-Speed Compression: Affects how the shock reacts to sudden, hard impacts. If you regularly ride over drops or aggressive trails, a firmer high-speed compression setting will prevent bottoming out.

Rebound Adjustment:

• Rebound controls how quickly the shock extends after compressing. If the rebound is too fast, the bike will feel bouncy. Too slow, and the shock will not return quickly enough, affecting handling. A balanced setting allows for a smoother ride.

Preload Adjustment:

• This adjusts the coil’s initial resistance. A higher preload setting increases the amount of sag before the shock compresses, making the ride firmer. For a softer, more responsive ride, reduce the preload setting.

Maintaining the DHX2 Performance Elite Rear Shock

Proper maintenance is crucial for keeping your DHX2 Performance Elite shock performing at its best. Follow these steps to extend the life of your shock:

1. Regular Cleaning: After every ride, wipe down the shock with a clean cloth to remove any dirt or grime. This will prevent contaminants from wearing down the components and damaging seals.
2. Inspect the Shock: Check for any signs of damage or wear, including leaks around the seals. If you notice oil or dirt buildup, it may indicate a need for service.
3. Lubricate the Shock: Every few rides, apply a small amount of shock-specific lubricant to the shock’s shaft. This helps maintain smooth movement and reduces wear on the shock seals.
4. Service Intervals: Fox recommends servicing the DHX2 Performance Elite every 50-100 hours of riding or at least once a year, whichever comes first. During servicing, the internal oil and seals should be inspected and replaced if necessary.

Troubleshooting Common Setup Issues

Even though the DHX2 Performance Elite rear shock is designed for high performance, you may encounter a few common issues. Here’s how to troubleshoot them:

Problem: Shock Bottoming Out

• Solution: If the shock is bottoming out during aggressive riding, increase the high-speed compression or the preload setting. You may also need to increase the air pressure or switch to a stiffer coil spring if the current one is too soft.

Problem: Bouncy Ride

• Solution: If the rear suspension feels overly bouncy, adjust the rebound damping to slow down the extension of the shock. You may also need to reduce the low-speed compression to firm up the ride.

Problem: Leaking Oil

• Solution: Leaks typically indicate an issue with the shock’s seals. If you see oil around the seals or on the shaft, it may be time to replace the seals or service the shock.

Customizing the DHX2 Performance Elite Rear Shock for Better Performance

The DHX2 Performance Elite shock is highly customizable. To get the most out of this shock, consider the following performance-enhancing adjustments:

1. Coil Spring Customization: Fox offers a variety of coil springs with different spring rates. If you are consistently riding on challenging, rocky terrain, consider upgrading to a stiffer coil for added stability. For lighter riders or smoother trails, a softer coil will provide a more compliant ride.
2. Compression Settings: Adjust the low-speed and high-speed compression based on the type of terrain you ride most often. Softer compression settings are better for smooth trails and long climbs, while firmer settings are better suited for technical downhills and aggressive descents.
3. Tune for Riding Style: Riders who prefer a more aggressive, downhill-oriented setup may benefit from stiffer compression settings and more rebound damping to prevent the shock from being too active. Riders who prioritize comfort might opt for a softer setup with more plush suspension.

Comparison with Similar Models

When comparing the Fox DHX2 Performance Elite rear shock to similar models like the RockShox Super Deluxe Coil or the Öhlins TTX Air, the DHX2 stands out in several areas:

• Customization: The DHX2 offers extensive customization options for both compression and rebound, which is ideal for riders who prefer fine-tuning their suspension settings.
• Durability: Fox’s DHX2 is known for its durability and high-quality materials, offering a long lifespan with proper maintenance.
• Coil vs. Air: The DHX2 uses a coil spring, which provides a more consistent feel and better small bump sensitivity than air shocks. However, air shocks tend to be lighter and more adjustable in terms of air pressure.

If you are looking for a rear shock that can handle aggressive downhill riding and offers the option for fine-tuning suspension settings, the DHX2 Performance Elite is an excellent choice. However, if weight is a critical factor for you, or if you prefer air shocks, the RockShox Super Deluxe or Öhlins TTX Air may be better alternatives.

Compatibility with Other Drivetrain Components

The DHX2 Performance Elite rear shock is compatible with a wide range of mountain bike frames and drivetrain systems. However, it’s essential to ensure that your bike’s geometry and rear triangle are suited to the dimensions of the shock. When choosing a shock, you should also take into account the type of suspension system on your bike. While the DHX2 works well with most modern designs, some frames may require additional adaptors or custom mounts.
