• Coil Spring Wrench
• Shock Pump
• Torque Wrench [paid link]
• 13mm Socket Wrench
• Grease
• Rubber Mallet
• Set of Allen Keys [paid link]
• Shock Eyelet Bushing Press
• Seal Driver Tool
• Cleaning Supplies (rags, degreaser)

Installation of the Deluxe Coil Ultimate Rear Shock

Installing the RockShox Deluxe Coil Ultimate rear shock is straightforward but requires precision. Follow these steps to ensure correct installation:

1. Preparing the Bike

Before you install the shock, remove the rear wheel and any other components that might obstruct your work area. This includes unhooking any cables or mounts that may be attached to the frame near the shock. Make sure you clean the shock mounting points on the frame to avoid introducing dirt or debris into the shock.

2. Installing the Shock

• Insert the shock into the shock mounts on the frame. Make sure the shock is oriented correctly and that the eyelet bushings align with the frame’s mounting holes.
• Secure the shock using the provided bolts. Tighten the bolts using a torque wrench [paid link] to the manufacturer’s recommended settings. This ensures that the shock is securely fixed without over-tightening, which could cause damage.
• Install the coil spring by placing it over the shock body, ensuring it sits firmly in place. Use the coil spring wrench to tighten the spring according to the manufacturer’s instructions.

3. Setting the Sag

Once the shock is installed, use a shock pump to adjust the air pressure to the recommended levels. Setting the proper sag is crucial for achieving optimal performance. Check the owner’s manual for the exact sag range for your rider weight.

4. Recheck and Test Ride

After installation, perform a test ride to check if the shock is functioning smoothly. Pay attention to any unusual noises or signs of excessive compression or rebound. If any problems arise, troubleshoot by double-checking the installation steps and settings.

Adjusting the Deluxe Coil Ultimate Rear Shock

The Deluxe Coil Ultimate rear shock offers several adjustments to help you fine-tune your ride. These include rebound, compression, and coil preload. Adjusting each of these settings properly will provide a personalized ride experience suited to your needs.

Rebound Adjustment

Rebound damping controls how quickly the shock returns to its original position after compression. If the shock is returning too quickly, the ride will feel harsh. If it’s too slow, it can result in a sluggish response.

• Turn the rebound knob counterclockwise to slow the rebound (slower return).
• Turn the knob clockwise to speed up the rebound (faster return).

Start with the factory setting and make small adjustments based on your preference and riding conditions. Keep in mind that your shock’s rebound needs might vary depending on the terrain you are riding.

Compression Adjustment

Compression damping regulates the shock’s resistance to compression during impacts. Adjusting the compression settings can provide more control on rough trails.

• The Deluxe Coil Ultimate features both low-speed and high-speed compression adjustments. Low-speed compression affects the shock’s response to slow compressions like pedaling forces, while high-speed compression affects the shock’s response to big hits.
• Use the dedicated knobs to adjust each setting. Begin with the factory default and make incremental changes. For smoother terrain, a softer compression setting may be ideal, while a firmer setting is better for rough, technical trails.

Coil Preload

Preload affects the initial compression of the coil spring. Increasing preload can stiffen the suspension, while reducing it allows for more initial sag and a softer feel.

• To adjust the preload, use the coil spring wrench to rotate the preload collar. Keep in mind that too much preload can result in a harsh ride, while too little can make the shock too soft for aggressive riding.

Maintenance and Servicing

Regular maintenance is key to keeping your Deluxe Coil Ultimate shock performing at its best. Follow these steps for proper upkeep.

Cleaning the Shock

Clean your shock after every ride, especially if you’ve been on muddy or wet trails. Dirt and grime can cause wear on the shock seals and other components. Use a clean rag to wipe down the shock body, paying particular attention to the air can, seals, and any areas where dirt may accumulate.

Checking the Coil Spring

Inspect the coil spring periodically for signs of wear or damage. If the spring becomes deformed, it can affect shock performance. Make sure the spring is seated properly and has no loose connections or cracks.

Inspecting the Seals

Inspect the seals on the shock every 20-30 hours of riding. If the seals are damaged or worn out, replace them to prevent air or oil leakage, which can significantly affect performance.

Changing the Oil

Changing the oil in the shock is crucial for maintaining optimal performance. Over time, the oil can degrade, reducing damping performance. Follow these steps:

• Remove the shock from the bike, and using a set of Allen keys [paid link], disassemble the shock.
• Drain the old oil and replace it with fresh suspension oil, following the manufacturer’s specifications.
• Reassemble the shock, making sure to replace any worn seals.

Spring and Seal Replacement

If you notice a significant decrease in performance, you may need to replace the spring or seals. Follow the manufacturer’s instructions for replacing these components and ensure that all parts are properly lubricated during reassembly.

Troubleshooting Common Set-Up Issues

If your Deluxe Coil Ultimate rear shock is not performing as expected, there may be a few common issues to troubleshoot:

1. Loss of Rebound or Compression Damping

If you notice a lack of rebound or compression damping, it could be due to air or oil leakage. Inspect the seals and look for signs of wear. If necessary, replace the seals or top up the oil.

2. Excessive Bottoming Out

If your shock is bottoming out on big hits, it could indicate insufficient air pressure or incorrect preload settings. Adjust the preload and check the air pressure with a shock pump. If the coil is too soft, consider using a stiffer spring.

3. Noisy Shock

A noisy shock can be caused by dirt buildup or improper lubrication. Clean the shock and check the coil for any signs of damage. Lubricate moving parts to reduce friction.

4. Poor Ride Quality

If the ride feels harsh or unresponsive, try adjusting the rebound and compression settings. If the shock continues to feel off, it may need a full service to replace worn parts.

Comparison with Similar Models

When considering suspension upgrades or replacements, it’s helpful to compare the Deluxe Coil Ultimate with other similar shocks. Compared to air shocks, the Deluxe Coil Ultimate provides a more consistent and plush ride, especially for riders who prefer coil-based systems. While air shocks are lighter and adjustable to a greater extent, the Deluxe Coil Ultimate offers superior small bump sensitivity and is ideal for riders who prioritize comfort on aggressive trails.

Understanding Compatibility with Other Drivetrain Components

The Deluxe Coil Ultimate is designed to work seamlessly with a variety of drivetrain components, particularly on full-suspension bikes. However, when replacing or upgrading your rear shock, ensure that the shock’s eyelet size, stroke length, and mounting hardware are compatible with your frame. If necessary, consult with a professional mechanic to confirm compatibility.

By keeping your shock properly maintained and adjusted, you will ensure that the Deluxe Coil Ultimate performs at its best, delivering a smooth and controlled ride for years to come.
