This guide will provide a step-by-step process for servicing your Float DPS Performance rear shock without the need for a professional mechanic. Whether you’re a seasoned rider or a beginner, the following instructions will help you perform essential tasks such as cleaning, lubing, and basic maintenance to keep your rear shock in top condition.

Tools Required

Before you begin servicing your Float DPS Performance rear shock, make sure you have the following tools:

  • Fox Float DPS Performance Service Kit (includes seals and oil)
  • Shock pump
  • 5mm, 6mm, and 8mm Allen wrenches [paid link]
  • 10mm spanner wrench
  • Oil syringe
  • Torque wrench [paid link]
  • Clean rags or cloths
  • Isopropyl alcohol or suspension cleaner
  • Latex gloves
  • Suspension fluid (e.g., 10wt or 5wt oil, depending on your shock specifications)
  • Rubber mallet (optional)

Preparation: Safety and Setup

Before diving into the maintenance process, it’s important to ensure you’re working safely and effectively.

  1. Place the bike in a stable position: Use a work stand or place the bike securely on the ground to ensure it remains steady during the service.
  2. Wear gloves: Gloves will protect your hands from oils and dirt.
  3. Clean the shock and surrounding area: Use a clean cloth and suspension cleaner to wipe away any dirt or debris around the shock. This prevents contaminants from entering the shock when it’s disassembled.

Disassembly of the Float DPS Performance Rear Shock

To service your Float DPS Performance rear shock, you’ll first need to remove it from the bike.

  1. Remove the rear shock from the bike:
    • Use the appropriate Allen wrenches [paid link] (usually 5mm or 6mm) to remove the bolts securing the shock to the frame.
    • Keep track of any washers or spacers that might be part of the mounting setup.
    • Carefully slide the shock off the mounting hardware.
  2. Remove the air canister:
    • Use a 10mm spanner wrench to remove the air canister from the shock body.
    • If the air canister is stuck, tap it gently with a rubber mallet to loosen it.
    • Set the air canister aside carefully, as it houses the positive air chamber.

Cleaning and Inspection

Once you have the shock disassembled, it’s time to clean it thoroughly and inspect for any damage.

  1. Clean the shock body:
    • Wipe the shock body with a clean rag soaked in isopropyl alcohol or suspension cleaner. Remove any dirt, grease, or oil build-up from the shock’s exterior.
  2. Inspect the shock components:
    • Check the shock body and the air canister for any visible damage or wear.
    • Inspect the seals in both the air canister and the shock body. If you notice any cracks, tears, or deformities in the seals, these will need to be replaced during reassembly.
  3. Clean the damper shaft and other internal parts:
    • Use a clean rag to wipe the damper shaft. Avoid using any solvents that might damage the internal components.

Replacing the Seals and Reassembling the Shock

Now that your shock is clean and all components have been inspected, it’s time to replace the seals and reassemble the shock.

  1. Replace the air canister seals:
    • Carefully remove the old seals from the air canister. This is typically done by prying them off with a flat tool or your hands, depending on their tightness.
    • Install the new seals from your Fox Float DPS Performance Service Kit. Ensure they are seated properly to avoid leaks during reassembly.
  2. Replace the seals in the shock body:
    • Remove the seals from the shock body, using a similar method to the air canister seals.
    • Install the new seals carefully, ensuring they fit snugly and correctly.
  3. Lubricate the shock:
    • Apply a thin layer of suspension fluid to the damper shaft and other moving parts to reduce friction.
    • Be careful not to over-lubricate, as excess oil can lead to leaks.
  4. Reinstall the air canister:
    • Carefully slide the air canister back into the shock body and tighten it using your spanner wrench.
    • Make sure the air canister is seated properly and securely.

Reinstalling the Shock on the Bike

With the shock reassembled, it’s time to reinstall it onto your bike.

  1. Mount the shock:
    • Slide the shock back into its mounting position on the frame.
    • Reattach the bolts securing the shock to the frame using your Allen wrenches.
    • Tighten each bolt to the manufacturer’s recommended torque specifications to prevent loosening during rides.
  2. Check for proper alignment:
    • Ensure that the shock is aligned properly within the frame and is not rubbing against any components. Misalignment can affect performance and cause wear on the shock or the frame.

Setting the Correct Air Pressure

Once the shock is reinstalled, it’s crucial to set the correct air pressure to ensure proper performance.

  1. Use a shock pump:
    • Attach a shock pump to the valve on the air canister.
    • Inflate the shock to the recommended pressure, which will vary depending on your weight, riding style, and shock model. Check the Float DPS manual or online specifications for the correct pressure range.
    • Make sure the shock holds the pressure after inflating. If it doesn’t, check for leaks in the seals or air canister.

Troubleshooting Common Issues

If you’re encountering issues with your Float DPS Performance rear shock, here are some troubleshooting tips:

  1. Shock is not holding air:
    • This is often due to damaged seals. Inspect and replace the seals, ensuring that they’re properly installed and lubricated.
  2. Suspension feels too soft or too firm:
    • Check the air pressure and adjust it based on your body weight and riding style.
    • If the suspension is still not performing correctly after adjusting air pressure, it may require a more thorough inspection or service, such as a damper rebuild.
  3. Suspension feels spongy or has a delayed response:
    • This could indicate internal fluid contamination or damage. Open the shock and inspect for issues such as dirty or low-quality oil. Refill and replace fluid as necessary.

Final Tips for Maintaining Your Float DPS Performance Rear Shock

  • Regular cleaning: After every ride, wipe down your shock to remove dirt and grime that can cause wear over time.
  • Check air pressure regularly: This is crucial for maintaining proper shock performance. Even slight changes in pressure can affect ride quality.
  • Follow the service schedule: Fox recommends servicing your Float DPS Performance rear shock at regular intervals, depending on the amount of riding you do. Typically, servicing every 50-100 hours of riding is a good benchmark.
  • Monitor for leaks: Always keep an eye on any potential leaks after servicing your shock. Small leaks can be a sign that seals were not installed properly or have worn out.

Servicing your Float DPS Performance rear shock at home is entirely feasible with the right tools and knowledge. By following these detailed steps, you’ll ensure your shock performs at its best, saving you money on professional services and extending the life of your bike’s suspension system.
