This guide will walk you through the steps needed to keep your rear shock in top shape.

Tools Required

  • 8mm hex wrench
  • 10mm socket wrench
  • Torque wrench [paid link]
  • Shock pump
  • DVO Jade Coil service kit
  • Seal press tool
  • Cleaning brush
  • Isopropyl alcohol
  • Silicone grease
  • Clean rags or towels
  • Latex gloves

Servicing the Jade Coil Rear Shock: A Step-by-Step Guide

1. Preparation

Before you begin any work on your Jade Coil rear shock, ensure that the bike is stable and properly secured. If necessary, remove the rear shock from the bike by using an 8mm hex wrench to detach it from the frame. You can also use a shock pump to reduce the air pressure before starting any disassembly.

2. Disassemble the Shock

  • Remove the Spring: Using your 10mm socket wrench, carefully unscrew the preload adjuster to release the tension on the coil spring. Slide the spring off the shock body.
  • Remove the Eyelet and Shaft: After removing the spring, you will need to take out the eyelet at the shock’s shaft. Use the appropriate tools from your service kit to carefully remove this piece without damaging the shock.

3. Clean the Shock

  • Use a cleaning brush and isopropyl alcohol to wipe down the shock body, eyelet, and shaft. Remove all dirt, debris, and old oil that may have accumulated. Pay special attention to the shock’s seals, as dirt can quickly degrade their performance.
  • Once cleaned, dry the components using a rag. It’s essential to avoid leaving any moisture on the parts before reassembly.

4. Replace Seals and Oil

  • Disassemble the Internals: To access the internal components, use the seal press tool from the service kit to remove the old seals carefully. Replace them with fresh seals, ensuring they are properly seated and free from any contaminants.
  • Add New Oil: Check the oil level inside the shock. Use the correct oil recommended by DVO for the Jade Coil, and fill the shock with the appropriate amount. When refilling the oil, make sure to follow the manufacturer’s guidelines for the oil type and quantity.

5. Reassemble the Shock

  • Once the seals and oil have been replaced, carefully reassemble the shock. Start by inserting the shaft and eyelet back into place, ensuring all parts are properly aligned.
  • Slide the coil spring back into place, tightening the preload adjuster to the desired setting. Use the torque wrench [paid link] to ensure proper tightening without over-tightening.

6. Reinstall the Shock on the Bike

  • Reattach the rear shock to the bike frame using the correct fasteners. Be sure to torque all bolts to the recommended values in the user manual.
  • Once installed, use a shock pump to re-pressurize the shock to your preferred settings, taking care not to exceed the maximum pressure limits.

7. Final Checks

After servicing and reinstalling the shock, perform a few checks:

  • Test the Functionality: Compress the shock by hand and observe if the suspension moves smoothly without any strange noises. If you hear any squeaks or notice resistance, double-check the assembly for any parts that may not be properly seated.
  • Check for Leaks: Ensure there are no oil leaks from the shock. If you see any leaks, carefully remove the shock and inspect the seals again.

Troubleshooting Common Jade Coil Rear Shock Issues

1. Excessive Rebound or Compression

If your Jade Coil shock feels too stiff or unresponsive, it could be due to incorrect rebound or compression adjustments. Adjust the rebound and compression dials slowly to find the ideal setting. If the shock still feels off after adjusting these, it may need a deeper inspection, such as a check of the oil levels or the seals.

2. Oil Leaks

Oil leaks from the shock can occur when the seals wear down or if the shock was overfilled during maintenance. Inspect all seals thoroughly when servicing the shock and replace them if necessary. If oil continues to leak, the shock might require more extensive servicing from a professional.

3. Noisy Shock

A noisy shock can result from dirt or debris getting caught in the seals. Ensure you clean the shock thoroughly during maintenance and lubricate the seals with a light coat of silicone grease to reduce friction and noise. If the noise persists, check the spring for any loose or damaged parts.

Customization and Optimization for Better Performance

To achieve the best performance from your Jade Coil rear shock, consider customizing it to match your riding style and terrain. Here are some options for optimization:

1. Spring Rate Adjustment

One of the key factors influencing your ride is the spring rate. Choose a coil spring with the right rate for your weight and riding style. A heavier rider will need a stiffer spring, while a lighter rider may prefer a softer one. By customizing the spring rate, you can achieve better control and comfort.

2. Rebound and Compression Settings

Tuning the rebound and compression settings allows you to adjust the shock’s responsiveness. Rebound controls how quickly the shock returns to its original position after compression, while compression controls how the shock reacts to bumps and impacts. Fine-tuning these settings will help you achieve a smoother, more controlled ride.

3. Adjusting Air Pressure

If your rear shock is air-sprung, adjusting the air pressure can improve performance. Higher pressure will result in a firmer shock, while lower pressure will make it softer. For riders seeking more plushness, lowering the air pressure can provide a more forgiving ride.

Compatibility with Other Drivetrain Components

The Jade Coil rear shock is compatible with a variety of mountain bike frames and suspension designs, but it’s essential to ensure that it’s matched to the other drivetrain components. For instance, check that your shock’s mounting hardware fits your frame’s rear shock mounts. Additionally, ensure that the shock’s travel and stroke are appropriate for your bike’s geometry. You should also verify that the spring rate and damping adjustments are suitable for your riding style and terrain.

Comparison with Similar Models

When choosing a rear shock, it’s useful to compare the Jade Coil with other models to understand its unique features and advantages.

1. DVO Jade X

The Jade X is a more premium version of the Jade Coil, offering enhanced damping options and increased adjustability. It features a higher level of customization for riders looking to fine-tune their suspension for competitive riding or specific terrain types. While the Jade X is more expensive, it offers more options for performance tuning.

2. Fox DHX2

The Fox DHX2 is another coil shock that competes with the Jade Coil in terms of performance. The DHX2 is known for its smoothness and consistency over rough terrain. However, the Jade Coil is often preferred for its simplicity and more straightforward tuning process, making it a good choice for riders looking for a reliable, easy-to-maintain shock.

3. RockShox Super Deluxe Coil

The RockShox Super Deluxe Coil is similar to the Jade Coil in terms of overall design and performance. It’s known for its lightweight design and excellent mid-range performance. However, the Jade Coil is often seen as having a slightly more tunable feel, particularly in the low-speed compression adjustments.

Conclusion

Servicing your DVO Jade Coil rear shock without a mechanic is entirely feasible with the right tools, proper techniques, and careful attention to detail. Regular maintenance, including cleaning, oil changes, and seal replacement, will ensure that your shock continues to provide the smooth, controlled ride it was designed for. By following the steps outlined in this guide, you can keep your Jade Coil rear shock in peak [paid link] condition, saving you both time and money while improving your overall riding experience.
